Compare two Excel workbooks
Load two .xlsx files and VS lines up both workbooks sheet by sheet, then highlights every cell whose value or formula text differs — with the two sheets scrolling together so the same row stays aligned.
Features & FAQ
- Cell-level diff across every worksheet
- Sheet picker to jump straight to the tab that changed
- Synced scrolling keeps the same row visible on both sides
- Runs entirely offline once the page has loaded
Frequently asked questions
- Are formulas compared, or just the displayed values?
- The stored cell content is compared, so an edited formula shows up as a change even when the value it evaluates to happens to match.
- What about .xls or .csv files?
- Export to .xlsx first. For .csv, the text tab gives you a line-by-line comparison of the raw content.
- Are my spreadsheets uploaded?
- No. The workbook is parsed in the browser and never leaves your device.
