Convert an Excel file to CSV, or a CSV to Excel — instantly, in your browser, with nothing uploaded.
Excel → CSV, or CSV → Excel (auto-detected). Everything runs in your browser — nothing is uploaded.
CSV and Excel are the two formats business data constantly bounces between. You export a customer list from one app as CSV and need it in Excel; or you have an Excel sheet and a tool that only accepts CSV. This free converter handles both directions in your browser — the file is never uploaded, so your data stays on your device.
Drop in an .xlsx (or .xls) file and it downloads a clean CSV of the first sheet; drop in a .csv and it downloads a proper .xlsx workbook. It detects the format automatically from the file, converts, and hands you the result. No signup, no watermark, and no row limits like some online converters impose.
A couple of practical notes: CSV is plain text with one sheet and no formulas or formatting, so converting Excel to CSV keeps the values but drops styling and multiple tabs — that’s expected and usually what a CSV import wants. Going the other way, CSV to Excel gives you an editable spreadsheet to format and add formulas to.

Both — an Excel file downloads as CSV, and a CSV downloads as an .xlsx Excel file. It detects the format automatically.
No — the conversion runs entirely in your browser. Your data never leaves your device.
