What this tool does
Spreadsheet and Excel Comparison gives you a fast, focused way to compare XLSX workbooks, individual worksheets, CSV files, or TSV files down to changed cells, formulas, and formats. Everything runs locally in this tab.
The result is produced only after the input is checked. If the value cannot be processed, the workspace reports a specific error instead of guessing.
Features
- All-sheet or selected-sheet comparison
- Same-workbook sheet comparison
- Added, removed, and modified sheet detection
- Cell value and formula comparison
- Number-format and style comparison
- Search, filters, navigation, and JSON export

- Review important output before using it in production.
- Very large inputs remain subject to browser memory limits.
- ExcelJS securely reads OOXML XLSX, not legacy XLS, XLSB, XLSM macros, encrypted workbooks, or ODS.
- Charts, images, conditional formatting, VBA, and every workbook-level property are outside this cell comparison model.
