How the result is produced
Provide the requested values, text, image, spreadsheet, or document; choose the relevant options; then run the operation. Review the structured preview before copying or downloading the result.
Result checks and practical limits
- Supports XLSX, XLS, CSV, and TSV files
- Compares a named worksheet or the first sheet
- Shows the cell address, old value, and new value
- Previews changes and exports them as CSV
Formulas are compared using values stored in the workbook. Macros are not executed and formulas are not recalculated. Large workbooks require more browser memory.
