Illustrative diff report and extension panel. Sample data, not a live comparison.
Find what changed.
Not just what’s there.
Compare two ranges in Google Sheets, or compare a saved snapshot with the current range. Review changes to values and formulas, cell by cell.
Comparisons run in the Chrome extension. This website requests no accounts, sheet access or uploads.

Set up the match
Compare by position, or match rows using a key column. Map columns when the two ranges are arranged differently.
