XlsCompareX is a Windows desktop tool for comparing spreadsheet and delimited text files side by side.
Open two files, inspect synchronized previews, jump across differences, and export the visible result set to CSV.
Compare `.xls`, `.xlsx`, `.xlsm`, `.xltx`, `.xltm`, `.csv`, and `.tsv` files from the same interface.
Review `Source` and `Target` together, select preview sheets independently, and keep both views aligned while you inspect cell changes.
Jump from the `Differences` grid to the matching cell, auto-fit both previews, filter visible results, and export the current list to CSV.
Use `Git Prev` to compare a locally modified file against its previous committed version when the file is already tracked by git.
Drop two files at once to populate `Source` and `Target`, or drag a single file directly onto the preview area to replace one side.
Built with .NET and WinForms for a lightweight native workflow without browser overhead or cloud dependency.
Review highlighted differences, synchronized previews, and exportable results in one window.
Download the latest release package, extract it, and run `XlsCompareX.exe` on Windows.
