Spreadsheet diff
Two spreadsheets.Every difference, in place.
SideBySheet renders both workbooks next to each other with synced scrolling and cell-level highlighting, so you read the changes in the sheet itself rather than in a list of changed cells.
Free, no account. Files are read in your browser and are not uploaded.

Why this one
Why this one
It runs on your Mac.
Today's paid spreadsheet comparison tools are Windows-only, and Microsoft's own Spreadsheet Compare has never shipped for the Mac. SideBySheet runs on macOS, Windows and Linux from the same codebase.
See it, then fix it.
Differences are highlighted cell by cell in the rendered sheet. Edit the changed cells inline and export a corrected workbook, without leaving the browser.
No Excel installation.
Files are parsed directly, so Office is not part of the setup and nothing has to be licensed before you can compare two files.
Free tool
The free web version
The browser tool does a full visual diff at no cost and without an account. It runs client-side: your files are read in the browser and are not uploaded.

A native desktop app for macOS, Windows and Linux is being built. It is not available yet — leave an email and you will hear when there is something to try.
