Tool purpose

The site provides browser-based spreadsheet tools for table conversion, row appending, sheet copying, and file splitting.

Keep backups

Keep every original file. Do not overwrite the only copy of important data with a generated workbook.

Check the result

Open each output and confirm row counts, headers, dates, identifiers, formulas, sheet names, and other important details before using it.

Workbook limitations

Charts, macros, images, external connections, advanced formatting, formulas, comments, and other workbook features may change or be removed. CSV and JSON conversions focus on table data.

Availability

Features may change or become unavailable. Generated files should not replace a reviewed data process when accuracy is important.

Contact

Use the contact page to report a reproducible technical issue. Do not submit confidential workbooks.
