What this tool does
Compare two spreadsheet versions cell by cell and download a clear change log with old and new values.
The tool parses the selected data locally, applies the requested operation, and creates a new downloadable result.
Browser-based workbooks do not execute VBA or reproduce every advanced Excel feature.
Supported formats
XLSX, XLS, CSV, and TSV inputs are supported where relevant. Generated results use XLSX, delimited text, or print-ready HTML according to the tool.
| Format | Support |
|---|---|
| XLSX / XLS | Values, formulas, and common sheet metadata |
| CSV / TSV | Plain tabular values; no workbook formatting |
Tips for better results
- Work on a copy when the workbook contains macros, charts, or complex formatting.
- Confirm the header row and target column before processing.
- Preview a few records after download before replacing any established workflow.
FAQ
Will this tool upload my spreadsheet?
No. Processing happens in your browser, and the selected file is not sent to Calloffice.
Does it change my original file?
No. Your original remains untouched; the tool creates a separate result file for download.
Can it handle formulas and formatted cells?
It reads common workbook content, but advanced Excel features may not survive every browser-based export. Keep a copy of the source workbook.
What should I do with a very large workbook?
Start with the relevant sheet and avoid unnecessary columns. Browser memory limits vary, so unusually large workbooks may need desktop spreadsheet software.
Why can a value look different after export?
CSV stores plain values only, while Excel can retain more types and formulas. Date, identifier, and large-number handling also depends on the selected options.
