XLSX TO CSV

Convert an Excel sheet to CSV.

Open an XLSX workbook, pick and filter the sheet you need, then download formula-safe CSV without uploading the source.

Open an Excel workbook

Your workbook stays in this browser. Choose an .xlsx file up to 50 MB.

What this tool changes

Workbook bytes stay in your browser. CSV and JSON exports contain the active sheet and visible rows. The editor writes a new value-only XLSX file; it does not preserve formulas, styles, macros, charts, or unsupported workbook metadata.
