Desktop and Online Applications for Spreadsheet Users

For users who need to quickly find differences between Excel files, we have created a free online comparison tool available directly on our website.

Developed by Spreadsheet Tools, our online Excel comparison application runs entirely in your web browser without uploading your files or data to our servers. It's an ideal solution when you need to quickly determine whether two Excel files contain any differences.

You can also generate a comparison report, save it to your computer, or share it with colleagues by email.

What Makes Our Online Tool Different?

Our online application combines a wide range of free features with a familiar, Microsoft Excel-like interface.

You can work with spreadsheets much as you would in Microsoft Excel. In addition to comparing two files, you can prepare and clean up your data before running a comparison: remove duplicate rows, delete empty rows and columns, or insert new rows and columns into your worksheets.

Spreadsheet Tools offers a free online alternative to Microsoft Spreadsheet Compare, combining spreadsheet comparison, data preparation, and interactive reporting in a single browser-based application.

Two Comparison Report Views

Our online tool offers two ways to review comparison results: side-by-side and consolidated views. Both make it easy to identify differences and analyze changes between two spreadsheets.

A dedicated differences panel provides a detailed list of detected changes, while the Legend lets you filter the results with a single click to display matching, modified, added, or deleted rows.

Whether you need to find missing records, identify changed values, or extract matching data, the comparison results are presented in a clear, easy-to-understand format.

No Limits

Our application has no built-in limits on file size or the number of rows it can process. You can work with anything from small Excel files to large spreadsheets containing hundreds of thousands of records.

The amount of data you can process depends only on your computer's available memory and processing power.

xlCompare is a desktop application for comparing Excel, CSV, XML, and text files.

It detects differences in cell values, formulas, cell formatting (fonts, text and background colors, text alignment, and number formats), comments, VBA code, and UserForms. xlCompare provides a comprehensive comparison of Excel files, helping you identify even the smallest changes.

xlCompare supports key-column comparison, including composite keys, as well as best-match comparison for identifying corresponding rows. Its advanced formula comparison algorithm breaks formulas into individual expressions, eliminating false differences caused by inserted or deleted rows and columns.

Command-line support enables integration with version-control systems such as Git, SVN, Perforce, and Mercurial, allowing you to compare different versions of Excel files, review changes, and resolve merge conflicts.

xlCompare is a free alternative to Microsoft Spreadsheet Compare. All comparison features available in Microsoft Spreadsheet Compare are included in the free version of xlCompare.
