XLSX
Browser only
Runs locally in your browser. Your files, pasted content and generated output are not uploaded. Reset clears this tool’s working data.
This tool needs JavaScript. If it does not load, refresh the page and try again.
How to use this tool
- Choose one or more XLSX files as supported by the controls.
- Choose a sheet number and the relevant options when shown. Process the spreadsheet and review the result.
- Download the result. Reset clears inputs and local results; Cancel stops an active worker.
Examples
A workbook with name/score columns for Alice (10) and Bob (20).
Limitations
- Clears the standard docProps/core.xml, app.xml and custom.xml property parts. Preserves worksheet XML. This is not a full personal-information scrubber: comments, hidden cells, custom properties stored elsewhere and user content may remain.
- Only unencrypted XLSX input is supported. Legacy XLS, XLSB, ODS, macros, embedded objects and external workbook links are rejected. Formulas use saved cached results and are never evaluated; recalculate missing cached results in your spreadsheet application first.
- 20 MiB per workbook; 40 MiB total input/output; 1–50 sheets; at most 50,000 rows per sheet, 500 columns and 500,000 cells. UTF-8 text input is limited to 5 MiB and cells to 32,767 characters.
- CSV/TSV exports prefix formula-like text with an apostrophe. JSON and YAML retain displayed cell text rather than inferring numeric/date types. XML uses the DTH named-field table mapping.
