If you’ve ever watched a municipal crew tap into a live water main without shutting off service to an entire neighborhood, you’ve seen saddleport technology at work — even if you didn’t know it by name. A saddleport, in the broadest sense, refers to a saddle-style pipe fitting that creates a new branch connection on an existing pipeline by clamping directly onto the outside of the pipe. It’s one of those quietly brilliant engineering solutions that most people never think about until they need one. Whether you’re a licensed plumber, a facilities manager, a civil engineer, or simply a homeowner trying to understand what’s happening beneath your lawn, this guide will walk you through everything you need to know — from how saddle fittings work to where and why they’re used across industries.

---

What Is a Saddleport and Why Does It Matter?

At its core, a saddleport is a pipe fitting designed to create a perpendicular outlet — or “port” — on an existing pipe without requiring you to cut out a section, install a tee from scratch, or interrupt the flow of whatever is running through the main line. The fitting literally saddles the host pipe, hugging its outer curve and locking into place via bolts, clamps, or a solvent-weld bond, depending on the materials involved.

The name itself is intuitive: just as a riding saddle drapes over the back of a horse and conforms to its shape, a saddle fitting wraps around the circumference of a pipe and conforms to its outer diameter.

The reason this matters is straightforward. In every one of these scenarios, engineers and tradespeople face the same challenge: how do you connect something new to something that already exists, often while it’s still in active use? The saddleport — and its many variants, including service saddles, tapping saddles, saddle tees, and saddle valves — is the answer that the industry has relied on for decades.

The Anatomy of a Saddle Fitting

Understanding how saddle fittings are constructed helps explain why they perform so reliably under demanding conditions. Most saddle fittings consist of a few core components, each serving a specific purpose in the overall assembly.

The saddle body itself is the curved main shell of the fitting.

The clamping mechanism varies by product type. Traditional service saddles use stainless steel or galvanized steel bolts and straps that wrap around the opposite side of the pipe, allowing the installer to apply even clamping pressure from both sides.

Finally, materials matter enormously. A stainless steel saddle is the go-to choice for aggressive or corrosive environments; bronze remains a time-tested standard for potable water applications; and PVC saddles dominate irrigation and drainage work because of their light weight, chemical resistance, and affordability.

---

Types of Saddle Fittings and Their Applications

The broad category of saddle-style fittings encompasses several distinct product types, each engineered for a specific range of tasks. Knowing which type to specify — or which one your contractor is using — can make the difference between a long-lasting installation and one that fails prematurely.

Service Saddles and Tapping Saddles

These are the workhorses of municipal water distribution. The AWWA M23 manual, which governs water main tapping practices in the United States, specifies that service saddles (also called service clamps) are appropriate for outlet sizes up to 2 inches; anything larger typically requires a tapping sleeve and valve.

The tapping saddle process is a variation on this theme. This is what enables the celebrated “wet tap” or “hot tap” technique: adding a new service connection to a pressurized, active water main without any interruption to existing customers.

Saddle Tees

Rather than opening up the structure and replacing a section of pipe with a factory tee, a plumber can drill or cut a hole, mount the saddle tee over it, and secure the fitting in place — sometimes with solvent cement, sometimes with clamps and bolts, depending on the specific product and application.

Saddle Valves

The saddle valve is a more controversial fitting that deserves honest treatment.

However, saddle valves have a well-documented reputation for leaking over time. The self-piercing needle creates a somewhat ragged hole rather than a clean, deburred opening, and the rubber sealing mechanism tends to degrade with age. Many local plumbing codes explicitly prohibit saddle valves, or restrict them to accessible locations only. Licensed plumbers frequently recommend against them, arguing that the time saved during installation rarely justifies the long-term leak risk. For low-volume appliance connections, a properly installed tee with a ball valve is the more reliable — and often code-compliant — alternative.

Schedule 80 PVC Saddles for Industrial Use

In chemical processing, water treatment, aquaculture, and manufacturing environments, the higher-pressure demands of the system call for fittings engineered to match. Schedule 80 PVC saddles offer significantly thicker walls than standard Schedule 40 fittings, giving them greater capacity to withstand elevated line pressure. Their resistance to a broad range of acids, bases, and industrial chemicals makes them a preferred choice wherever metal corrosion is a concern.

How to Install a Saddle Fitting: A Practical Walkthrough

Installation procedures vary by fitting type and material, but the core steps follow a consistent logic that applies to most saddle applications.

The first task is pipe preparation. Before the fitting goes on, the pipe surface at the intended installation point should be clean, dry, and free from burrs, scale, or surface damage. For underground work, that means removing any soil or debris from the pipe surface and inspecting for corrosion or structural irregularities that could compromise the seal. Manufacturers like JCM Industries explicitly state in their installation instructions that confirming the pipe’s outside diameter and surface condition is the installer’s responsibility before proceeding.

Next comes positioning.

The cutter is fed through the open valve into the pipe wall, cutting a clean hole and capturing the resulting “coupon” — the small disc of pipe material — so it doesn’t enter the flow stream downstream.

Torque matters more than most installers appreciate. Over-tightening bolts can deform the pipe, particularly on thin-walled or flexible polyethylene pipes. Under-tightening compromises the gasket seal. Professional contractors use calibrated torque wrenches for critical installations, and manufacturers typically specify torque ranges in their installation documentation.

---

Saddleport Technology in Municipal Water Infrastructure

The scale at which saddle fittings operate in municipal settings is genuinely impressive. A medium-sized city might have thousands of service connections tapped into its distribution mains, with each connection relying on a saddle-type fitting of some kind. Water utilities turn to these fittings not only for new service installations but also for system expansion projects, emergency repairs, and pressure monitoring point installations.

The AWWA (American Water Works Association) standards govern much of this work in the United States, providing guidance on appropriate tapping methods for different pipe materials including ductile iron, PVC, and HDPE.

Hot tapping, in particular, represents a significant operational advantage for utilities. In densely populated areas, where even a brief service interruption affects hospitals, restaurants, and thousands of households, this capability is not merely convenient — it’s essential.

The economic argument is equally compelling. Avoiding a planned shutdown means avoiding the cost of customer notifications, the operational complexity of valve sequencing, and the mandatory bacteriological testing and pressure testing that must follow any shutdown and restoration of a potable water main. Hot tapping, enabled by saddle fittings and tapping sleeves, eliminates all of these steps.

---

Choosing the Right Saddle Fitting for Your Application

Selecting the appropriate saddle fitting involves more than simply matching pipe diameter. Several variables should guide the decision, and getting them right from the outset will save time, money, and potential rework down the line.

The pipe material is the starting point. Ductile iron mains, which remain common in older municipal systems, pair well with brass, bronze, or stainless steel service saddles. PVC and HDPE pipes call for fittings that won’t damage the pipe wall during installation — saddles with smooth, contoured bearing surfaces rather than lugged designs that can bite into the plastic under clamping pressure. The AWWA M23 guidance specifically warns against saddle designs with lugs that ding the pipe, U-bolt straps that concentrate load over a narrow bearing area, or clamping arrangements that don’t conform to the pipe’s outer diameter.

The pipe’s Standard Dimension Ratio (SDR) — a measure of wall thickness relative to outside diameter — is especially important for HDPE pipe. Higher SDR numbers indicate thinner walls, which are more susceptible to deformation under saddle clamps. Extra care in hardware selection and torque management is essential for high-SDR polyethylene pipe.

System pressure is another critical factor. Pressure ratings vary significantly between product lines. Always verify that the fitting’s pressure rating exceeds the maximum operating pressure of the system, with a reasonable safety margin factored in.

Finally, consider the end-use environment. NSF/ANSI 61 certification is mandatory for any fitting that will contact potable water — this standard ensures that the fitting’s materials don’t leach contaminants into the water supply, and responsible contractors and utilities won’t specify fittings that lack it.

---

Common Mistakes and How to Avoid Them

Even experienced installers occasionally run into problems with saddle fittings, and most of them are preventable with a bit of care.

One of the most frequent errors is installing the saddle on a curved or irregular section of pipe, where the saddle body can’t achieve full contact around the circumference. Always choose a straight, smooth section of pipe, and inspect it thoroughly before proceeding.

Mismatched sizes are another common pitfall. Saddle fittings are sized by the outside diameter of the host pipe, not the nominal pipe size — and outside diameter and nominal size don’t always match. A 4-inch nominal PVC pipe has a different outside diameter than a 4-inch nominal ductile iron pipe, so the saddle specified must match the actual outside diameter of the specific pipe in the ground, not just its nominal designation.

Skipping the pressure test before drilling into a live main is a risk that can end catastrophically. Most installation procedures call for the assembled saddle to be tested with a hydrostatic pump before the tapping tool is engaged. This step confirms that the gasket is seated correctly and the bolts are torqued properly, so that when the hole is cut, the fitting holds.

Trends and Innovations in Saddle Fitting Technology

The saddle fitting industry, while not glamorous, has seen meaningful innovation over the past decade. Self-tapping saddle designs — like those produced by Blazing Products and similar manufacturers — eliminate the need for a separate drilling step entirely. A patented cutting tip on the fitting itself cuts cleanly through polyethylene pipe when the outlet is twisted into position, creating a hole and a seal simultaneously. These self-tapping saddles have become especially popular in drip and micro-irrigation applications, where dozens or hundreds of saddle connections might need to be made across a single field or landscape installation.

Smart integration is an emerging frontier. Some saddle-style fittings are now designed to accommodate inline sensors, pressure transducers, and flow measurement devices, essentially turning the saddle port into an instrumentation access point on an existing pipeline. This approach enables utilities and industrial operators to monitor system performance at specific locations without the cost of installing a full bypass or isolation spool.

Material science advances have also broadened the application envelope. High-performance thermoplastic compounds now allow saddle fittings to be specified for applications that once required metal hardware — reducing weight, eliminating corrosion concerns, and in some cases bringing down installed cost significantly. HDPE saddles with electrofusion outlets, for example, can be welded directly to an HDPE main, creating a monolithic, fully fused joint with no mechanical seal required — a connection that is arguably stronger than the pipe itself.

---

Conclusion: The Understated Importance of the Saddle Port

The saddleport may not be the most talked-about component in a plumbing or water distribution system, but its impact is felt every time someone opens a tap, runs a sprinkler, or benefits from a municipal infrastructure expansion that required zero service interruption. From the residential plumber adding a branch to an irrigation main, to the utility contractor tapping into a live 12-inch water main under city streets, saddle-style fittings are the connective tissue that makes modern pipe networks adaptable, expandable, and maintainable.

Choosing the right saddle fitting — the right material, the right pressure rating, the right design for the host pipe — is genuinely consequential work. A fitting that fails underground or inside a wall can cause extensive damage; one that’s correctly specified and carefully installed will quietly outlast the infrastructure around it. The key takeaway from this guide is that saddle fittings reward careful attention to detail: matching materials, confirming dimensions, respecting torque specifications, and verifying pressure ratings before the system goes live. Do those things well, and the saddleport will do its job without you ever thinking about it again — which is exactly how good infrastructure should work.

Introduction

If you’ve ever stared at a sprawling, multi-level spreadsheet and wondered how to bring everything into a single, usable format, you’re not alone. The need to flatten sheet is one of the most common — and most underestimated — tasks in data management. Whether you’re working in Microsoft Excel, Google Sheets, Power Query, or a database environment, knowing how to collapse nested structures, merge hierarchical data, and produce a clean, analysis-ready table can save hours of manual work. It also makes your data compatible with virtually every downstream tool, from pivot tables and dashboards to machine learning pipelines. This guide walks you through the concept, the methods, the real-world scenarios, and the modern best practices that turn flattening from a frustrating chore into a confident, repeatable skill.

What Does It Mean to Flatten Sheet?

At its core, flattening a sheet means taking data that is organized in a multi-dimensional, hierarchical, or nested structure and converting it into a single flat table — one where every piece of information lives in its own row and column, with no merged cells, no grouped rows, no sub-headers, and no collapsible sections.

Think of a typical sales report generated by accounting software. It might show regions as top-level headers, with product categories as sub-headers beneath them, and individual transactions nested under those. This structure looks attractive in a printed report, but it is essentially unworkable for any kind of data analysis. A pivot table cannot read it properly. A VLOOKUP will fail. An import into a CRM or database will produce errors or garbage output.

Flattening resolves this by bringing everything to the same level. Each row becomes a self-contained record, carrying all the context it needs — region, category, product, date, amount — in clearly labeled columns. This normalized format is the foundation of relational databases, and it is what every serious analytics tool expects.

There is also a slightly different meaning of the term in the context of Power Query and Excel’s data model: “flattening” can refer to removing the expand/collapse functionality from grouped rows, converting an outlined spreadsheet into a static, linear layout. Both meanings share the same underlying goal — clarity, simplicity, and compatibility.

Why Flattening Data Matters More Than Ever

The demand for clean, flat data has grown substantially as organizations increasingly rely on tools like Power BI, Tableau, Looker, and Python-based analytics libraries. These tools are built around the concept of tidy data — a term coined by statistician Hadley Wickham — where each variable forms a column, each observation forms a row, and each type of observational unit forms a table.

Hierarchical spreadsheets, crosstab reports, and pivot-style layouts violate these principles. They work beautifully for human eyes reading a printed page, but they become major obstacles the moment you try to automate, visualize, or analyze the underlying information.

Consider a real-world example from supply chain management. A warehouse team might maintain an Excel workbook where each product category has its own grouped section, with sub-rows for individual SKUs and summary rows at each level. When an analyst tries to load that data into a dashboard tool or feed it into an inventory forecasting model, the tool either crashes, misinterprets the hierarchy, or requires hours of manual cleanup. Flattening that sheet — even once — and maintaining the flat format going forward eliminates an entire category of data headaches.

Beyond analytics tools, flat data is also essential for data sharing. When you send a structured spreadsheet to a business partner, a government agency, or an API endpoint, they almost never want your formatting. They want rows and columns with consistent headers. Flattening before sharing is not just good practice; in many professional contexts, it is an expectation.

Common Structures That Need Flattening

Before diving into the methods, it helps to recognize what you’re dealing with. Several recurring data structures tend to require flattening.

Merged Cell Layouts

Merged cells are the single most common obstacle to working with spreadsheet data programmatically. A dataset where “Q1 2024” is merged across six columns might look tidy in print, but it means only one cell in that range actually contains a value. Every downstream operation — sorting, filtering, formula referencing, exporting — treats those blank-looking cells as genuinely empty, producing gaps, errors, and miscounts.

Unmerging and filling down the repeated values is one of the most basic forms of flattening. Excel’s built-in “Unmerge Cells” feature can unmerge them in one step, and a simple “Fill Down” or a Go-To Special selection of blank cells followed by a formula referencing the cell above can propagate the header values into every row where they belong.

Multi-Row Headers

Reports exported from enterprise systems — SAP, Oracle, QuickBooks, legacy ERP platforms — frequently come with two or three header rows stacked on top of each other. The first row might say “Revenue” spanning several columns, while the second row specifies “January,” “February,” “March,” and so on. This is a crosstab or matrix format, and while it looks organized, it requires concatenation and reshaping before it can be used analytically.

Flattening this type of structure typically involves combining the header rows into a single descriptive header (e.g., “Revenue_January,” “Revenue_February”) and then treating the data rows as individual records. This reshaping process is sometimes called “unpivoting” or “melting” the data.

Grouped and Outlined Rows

Excel’s grouping and outlining feature allows you to collapse and expand sections of a spreadsheet using the plus and minus buttons on the left margin. These are convenient for navigation but create structural complexity that can confuse exports and imports. Removing the grouping — through Data > Ungroup or by clearing the outline — produces a flat, linear list that is far more portable.

Nested JSON or XML Imported into Sheets

With the rise of API-driven workflows, many teams now receive data in JSON or XML format and import it into a spreadsheet. If the source data contains nested objects or arrays, the import often produces a multi-level column structure that mirrors the original nesting. Flattening this means expanding every nested level into its own column, a process that tools like Power Query handle particularly well through its “Expand” functionality.

How to Flatten a Sheet in Microsoft Excel

Excel offers several approaches depending on how your data is structured and how comfortable you are with its more advanced features.

Using Unmerge and Fill Down

The quickest manual method for dealing with merged cells involves selecting the entire dataset, going to Home > Merge & Center dropdown > Unmerge Cells, and then using Go-To Special (Ctrl+G > Special > Blanks) to select all the newly empty cells. With those cells selected, you type an equals sign followed by the address of the cell above (for example, =A2 if you’re in A3), and confirm with Ctrl+Enter to fill all selected blanks simultaneously. Converting the formulas to values immediately after prevents them from shifting if rows are later inserted or deleted.

This approach handles merged header columns quickly and reliably, and it works well even on large datasets where manual filling would be impractical.

Using Power Query for Structural Flattening

Power Query — accessible through the Data tab in Excel 2016 and later — is arguably the most powerful tool available for flattening complex data structures. It is especially useful when you’re dealing with multi-row headers, grouped data, or imported JSON.

To flatten a crosstab or pivot-style table, you load your data into Power Query, select the columns that should remain as identifiers, and use the “Unpivot Other Columns” option. This transforms each value in the pivoted columns into its own row, creating the normalized structure that analysis tools require. The result is a clean, long-format table where each row represents a single observation.

For nested data imported from JSON or XML, Power Query’s “Expand Column” button appears automatically when it detects list or record values in a cell. Clicking it — sometimes repeatedly for deeply nested structures — progressively flattens the hierarchy until every value occupies its own column.

One of Power Query’s most valuable characteristics in this context is that the transformation steps are recorded and reproducible. Once you’ve built the flattening logic, refreshing the query with new data applies all the same steps automatically. This makes it ideal for recurring reports that arrive in a messy format and need to be flattened on a regular basis.

Using VBA for Automated Flattening

For teams that work with highly specific or unusual data structures that Power Query cannot handle elegantly, a short VBA macro can automate the flattening process. A basic macro might loop through a range, detect merged cells, unmerge them, and fill down values — all in a few dozen lines of code. More sophisticated scripts can detect outline levels, remove groupings, and restructure multi-row headers by concatenating them.

VBA-based flattening is particularly useful in enterprise environments where the same messy report arrives weekly or monthly and the structure never changes, making automation worthwhile even if it requires some initial setup time.

---

How to Flatten a Sheet in Google Sheets

Google Sheets offers fewer native tools than Excel for deep structural flattening, but it handles the most common scenarios reasonably well.

For unmerging and filling, the process is similar to Excel: select the merged cells, go to Format > Merge Cells > Unmerge, and then use a formula-based approach to fill blank cells downward. The ArrayFormula function combined with conditional logic can automate this fill-down process across an entire column in a single formula, which is more elegant than the Excel equivalent.

Google Sheets does not have a native equivalent of Power Query, but it integrates well with Google Apps Script — the platform’s built-in JavaScript environment — for more complex transformations. Apps Script can loop through rows, detect structural patterns, and produce a flattened output sheet automatically. For teams that rely heavily on Google Workspace, writing a simple Apps Script to flatten incoming report data can dramatically reduce manual data preparation time.

There is also a growing ecosystem of third-party add-ons and integrations — including Coupler.io, Supermetrics, and various ETL connectors — that can pull data from external sources and deliver it in a pre-flattened format, bypassing the structural complexity entirely.

Flattening Data in Python: pandas and Beyond

For data professionals who work outside the spreadsheet interface — or who need to process very large datasets — Python’s pandas library provides the most flexible and scalable approach to flattening sheet-style data.

The pandas.read_excel() function can import Excel files directly, and the melt() function is the primary tool for converting wide, crosstab-style data into long, flat format. A typical workflow might load a report with multiple header rows using the header parameter to specify which rows to use, then rename the resulting multi-level column index into a flat set of descriptive labels, and finally call melt() to unpivot the value columns.

For JSON data, pandas.json_normalize() is specifically designed to handle nested structures. It traverses the hierarchy and produces a flat DataFrame where nested keys become column names joined by a separator — for example, a nested key like {"address": {"city": "Karachi"}} becomes a column named address.city. Additional arguments control how deeply the function recurls into the structure and which list fields to expand into separate rows.

The advantage of Python-based flattening over spreadsheet tools is not just scalability. It also enables unit testing, version control, and integration into automated data pipelines. A flattening script that runs reliably on a schedule, logs its operations, and raises alerts when the input structure changes unexpectedly is a far more robust solution than a human manually cleaning a spreadsheet each month.

---

Flattening Hierarchical Data in Databases

In SQL environments, the concept of flattening data takes on a specific technical meaning: converting a self-referencing table — where a column like parent_id creates a tree structure — into a flat result set where the hierarchy is resolved into columns or repeated rows.

A common example is an organizational chart stored as an employee table, where each row has a manager_id pointing to another row in the same table. Reporting tools often need this hierarchy “flattened” so that each employee’s row includes the names of their direct manager, skip-level manager, and department head — all in the same row, as separate columns.

Recursive Common Table Expressions (CTEs) in SQL are the standard mechanism for traversing these hierarchies. A recursive CTE starts at the root nodes, joins to their children, and continues joining to the next level until the entire tree is resolved. The result can then be joined back to the main table to produce a flat, denormalized view that downstream applications can consume without needing to understand the original tree structure.

This type of flattening is also common in product catalog management, where categories form multi-level trees, and in financial reporting, where cost centers and accounts are organized in hierarchical charts.

Best Practices for Maintaining Flat Data

Flattening a sheet is sometimes a one-time rescue operation, but ideally it becomes part of how your team designs and maintains data from the start. A few principles make this easier to sustain.

Establishing naming conventions for columns prevents ambiguity and makes flat tables self-documenting. Instead of importing a report with a column called “Jan” that appears in multiple contexts, a well-structured flat table uses a column like metric_name with the value “Revenue” and a separate month column with the value “January.” This may seem more verbose, but it makes filtering, aggregation, and interpretation dramatically more reliable.

Separating presentation from storage is the cultural shift that prevents the problem from recurring. Reports that are designed for human reading can be generated from flat source data using formatting tools — they do not need to be the storage format. Maintaining a clean, flat data file as the source of truth and generating pretty reports from it as needed is a far more durable workflow than trying to extract meaning from formatted reports later.

Automating the flattening step wherever possible — whether through Power Query, Apps Script, Python, or a proper ETL tool — removes human error and ensures that the process runs consistently. Documented, automated transformations are also far easier to audit, debug, and hand off to colleagues than undocumented manual processes.

Modern Tools and Trends in Data Flattening

The tooling landscape around data preparation and flattening has evolved significantly in recent years. Low-code platforms like dbt (data build tool) have brought software engineering practices — version control, testing, documentation — into the world of data transformation, making flattening operations in SQL environments more structured and maintainable than ever.

At the same time, tools like Trifacta (now Alteryx Designer Cloud), Talend, and Microsoft Fabric’s data pipeline features bring visual, point-and-click interfaces to complex flattening and reshaping operations, making these capabilities accessible to users who are not comfortable writing code.

Even spreadsheet tools themselves have become more capable. Excel’s newer array functions — such as TOCOL, TOROW, VSTACK, and HSTACK — introduced in recent versions, allow users to reshape and combine data ranges without leaving the spreadsheet environment or writing macros. These functions represent a significant step toward making structural transformations more accessible to everyday spreadsheet users.

AI-assisted data preparation is also emerging as a practical trend. Tools that use natural language interfaces — including some integrations with large language models — can recognize hierarchical patterns in uploaded data and suggest or apply appropriate flattening steps. While this technology is still maturing, it signals a future where the technical barrier to producing clean, analysis-ready data continues to lower.

Troubleshooting Common Flattening Problems

Even with the right tools, certain issues arise frequently when flattening spreadsheet data.

Duplicate rows after unpivoting are one of the most common surprises. They typically indicate that the original dataset had multiple rows with the same identifier values, or that the unpivot operation created cartesian combinations that weren’t intended. Reviewing the original structure carefully and ensuring that the identifier columns truly form a unique key for each record — before unpivoting — usually resolves this.

Missing or misaligned values after filling down merged cell headers often occur because the original merge spanned rows inconsistently, or because rows were hidden before the unmerge operation. Unhiding all rows and ensuring no filters are active before beginning the unmerge and fill-down process prevents most of these issues.

Performance problems when flattening very large files in Excel or Google Sheets can often be addressed by loading the data into Power Query (Excel) or a Python environment rather than working with it directly in the grid. These environments are optimized for data transformation in ways that the spreadsheet grid is not.

Conclusion

Learning to flatten a sheet is one of those foundational data skills that quietly multiplies your effectiveness across every other task you do with data. The ability to take a nested, hierarchical, or structurally complex spreadsheet and transform it into a clean, analysis-ready table opens the door to better reporting, more reliable automation, and smoother collaboration with tools and teammates that expect normalized data.

Whether you’re unmerging cells in Excel, unpivoting columns in Power Query, melting DataFrames in pandas, or resolving recursive hierarchies in SQL, the underlying principle is the same: make the structure serve the data, not the other way around. The insights you need are already in your spreadsheet. Flattening it is simply the act of making them accessible.
