Is Row Excel Open Source? Ownership and Alternatives

If you mean Row or Rows, the online spreadsheet often described as an Excel alternative, no: it is not an open-source version of Excel. It is proprietary software, as is Microsoft Excel, so neither product provides its full source code under an open-source license.

What does Row refer to?

The name can be confusing because “row” is also a basic spreadsheet term, and several products use similar names. In this question, Row usually means a web-based spreadsheet product positioned as a more collaborative, connected alternative to Excel. Rows, with an s, is another name readers may encounter for an online spreadsheet with a similar pitch. Those names do not refer to Microsoft Excel itself.

Check the exact product name, web address, and publisher before making a decision. A search result or comparison page may use “Row,” “Rows,” or “Excel alternative” loosely, even when it describes a different service. The answer about open-source status here concerns the commercial online spreadsheet commonly meant by Row or Rows, not every application with a similar name.

It is also useful to separate a product’s licensing from its availability. A service might change its plans, features, or operating status without becoming open source. If you are considering a particular Row-branded service, verify its current official information before relying on it for important work.

What open source means in this case

Open source is more than being free to use or available in a browser. Software is generally called open source when its code is made available under a license that permits people to inspect, use, modify, and redistribute it under stated conditions. The license matters: seeing code online does not automatically give everyone permission to reuse it, and a public help page or API guide is not the application’s source code.

A proprietary spreadsheet can still offer a free plan, a trial, or integrations with other services. Those features affect access and functionality, not whether the program is open source. Likewise, a company may publish a small connector or software library while keeping its main spreadsheet application closed. To assess a claim, look for a public source-code repository, a clearly identified open-source license, and permission to modify and redistribute the relevant software.

Row’s online spreadsheet product is not presented as a community-developed, open-source spreadsheet that users can download, fork, and run themselves. Treat it as proprietary unless the specific publisher provides a current license and source repository that demonstrate otherwise.

How Row compares with Microsoft Excel

Row and Excel are separate products, not two editions of the same program. Excel is Microsoft’s spreadsheet application, available through Microsoft 365 and other Microsoft offerings. Row was marketed as an online spreadsheet built around collaboration and connecting spreadsheets to outside data or services. A similar grid layout or support for familiar spreadsheet concepts does not mean the products share code or licensing.

Excel is proprietary too. Microsoft does not publish the complete Excel application source code for users to modify and redistribute under an open-source license. The .xlsx file format is based on a published Office Open XML standard, but an open or documented file format does not make the software that reads and writes it open source. A program can support .xlsx files while remaining closed source, and an open-source program can read or write .xlsx files without being Excel.

For a practical comparison, consider where the spreadsheet runs, how people collaborate, which file types it handles, and whether it connects to the services you use. Also check whether a feature is available in the specific version or plan under consideration; broad descriptions such as “Excel compatible” do not promise identical behavior for every workbook.

How an online spreadsheet works

A browser-based spreadsheet typically stores workbooks in a hosted service rather than treating a file on one computer as the only copy. This can make it easier for several people to view or edit a document and can support connections to online data sources. In Row’s case, the product was associated with collaborative spreadsheet work and integrations, rather than simply being a locally installed Excel clone.

That model has trade-offs. Users depend on the provider’s infrastructure, account system, terms, and supported features. Some work may require an internet connection, and a team may need to consider how data is stored and who can access it. Those are product and service questions, not signs of whether the underlying software is open source.

Integrations also need careful interpretation. A spreadsheet that can connect to an API or import information from another service can be useful, but that does not make the integration code or the spreadsheet itself open source. Check what permissions a connection requests, what data it transfers, and whether it continues to work if a provider changes its service.

Can you inspect, modify, or self-host Row?

For an open-source product, a user can often inspect its published code and may be able to modify or self-host it in line with the license. A proprietary hosted spreadsheet does not generally offer those rights. Access to a web app, export tools, integrations, or an API is not equivalent to permission to run a modified copy of the product.

If self-hosting or long-term control is a requirement, look for explicit evidence before choosing a spreadsheet: a maintained public repository, a license that allows the intended use, installation instructions, and a clear explanation of what components must still come from a vendor. Some products have open-source editions alongside paid services, so confirm that the edition you plan to deploy includes the functions your team needs.

For any hosted spreadsheet, plan for the possibility that access or product terms could change. Keep appropriate exports, document important workflows, and test that exported files contain the values and formulas your team needs. This is sensible continuity planning for cloud software generally; it does not imply that a particular service is about to close.

Free, open source, and paid are different

People often use “free” to mean several different things: no charge, no usage limit, access to source code, or freedom to run a copy on their own server. These meanings are not interchangeable. A proprietary product may have a free tier with limits, while an open-source spreadsheet may be free to download but require paid hosting, support, or administration.

Before comparing costs, list the features that matter and check the current terms. Relevant questions include:

Is there a charge for each user, and are there limits on workbooks, storage, or usage?
Are collaboration, integrations, and administrative controls included in the plan you need?
Can you export your data in a format another spreadsheet can use?
For self-hosted software, who will install updates, manage backups, and secure the server?

Those questions help prevent a common mismatch: selecting a tool because it is free to start, then discovering that a needed feature, export option, or deployment method is available only under different terms.

Open-source spreadsheet alternatives

If the key requirement is open-source software rather than a particular Row feature, several established projects are worth comparing. Their capabilities and compatibility differ, so try representative files and workflows before moving a team’s work.

LibreOffice Calc: A free, open-source desktop spreadsheet for Windows, macOS, and Linux. It can work with common Excel formats, including .xlsx, though complex workbooks, macros, and specialized Excel features may not behave exactly the same.
ONLYOFFICE Spreadsheet Editor: An open-source spreadsheet option with desktop and deployment choices. Licensing and included features can vary between community and commercial offerings, so check the terms for the edition you intend to use.
Gnumeric: An open-source spreadsheet application associated with the GNOME desktop environment. It may suit users seeking a desktop alternative, but check platform support and compatibility against your actual files.
EtherCalc: An open-source web-based spreadsheet project designed for collaborative editing. It is a lighter option to investigate, not an automatic replacement for every Excel feature or a guarantee of managed, enterprise-ready hosting.

Google Sheets and Apple Numbers are other familiar spreadsheet choices, but they are not open-source applications. They may be useful alternatives for collaboration or personal work, yet they do not meet a requirement to inspect and modify the spreadsheet program’s source code under an open-source license.

How to choose a suitable alternative

Start with the reason you are asking whether Row is open source. If you need code you can audit or modify, prioritize licensing and the availability of a complete source repository. If your goal is simply to avoid a subscription, compare free plans and desktop applications, but do not assume that a no-cost service is open source. If self-hosting is essential, check the installation and maintenance requirements as carefully as the feature list.

Next, test compatibility with real workbooks. Use copies of representative files, including any with charts, pivot tables, external links, macros, or complex formulas. Confirm that formulas calculate correctly, formatting survives, and collaborators can access the workbook as expected. Excel-specific automation may require particular Microsoft software and should not be assumed to transfer to another application.

Finally, consider operational needs: backups, access controls, updates, support, and data location. An open-source license can provide more control over software, but it does not by itself provide secure hosting, reliable backups, or someone to maintain a server. A hosted proprietary service can reduce administrative work while offering less control over its implementation. The better choice depends on which trade-off matters most to you.

Frequently Asked Questions

Is Row the same as Microsoft Excel?
No. Row or Rows refers to a separate spreadsheet product, while Excel is Microsoft’s spreadsheet application. Similar grids, formulas, or file support do not make them the same program.

Is Row free to use?
Pricing and availability can change, and a free tier is not the same as open-source software. Check the official information for the exact product and plan, including any limits on users, features, or data.

Can I use Row offline?
Do not assume that a browser-based spreadsheet works offline. Offline access depends on the particular product and its current features. If offline work is important, verify it directly or consider a desktop spreadsheet application.

Can I self-host Row?
Not on the basis of a web account or an integration alone. Self-hosting requires the publisher to provide software and a license that permit deployment. Look for those explicitly; otherwise, consider an open-source project with documented self-hosting options.

Which open-source spreadsheet is closest to Excel?
LibreOffice Calc is a common desktop alternative, while ONLYOFFICE is another option to evaluate. Neither should be assumed to reproduce every Excel feature exactly, so test your important workbooks and workflows before switching.
