Excel to CSV

Convert Excel spreadsheets (XLSX, XLS, ODS) to CSV in your browser, with per-sheet selection and delimiter options.

No spreadsheet selected

Upload an XLSX, XLSM, XLSB, XLS, or ODS file up to 25 MB. Each sheet can be exported separately. Parsing happens locally in your browser.

Your spreadsheet is parsed entirely on your device and never uploaded. The downloaded CSV includes a UTF-8 byte-order mark so it reopens correctly in Excel.
