Excel to CSV Converter: XLSX and XLS
Convert Excel to CSV in your browser. Choose an XLSX, XLS or ODS file, pick the sheet, choose a comma, semicolon, tab or pipe separator, preview the first rows and download the CSV. You can also download every sheet as its own file. Add a UTF-8 BOM if accents look wrong when you reopen the CSV in Excel. Your spreadsheet is read on your device and is never uploaded, so it is safe for private data.

Frequently asked questions
How do I convert Excel to CSV?
Choose your Excel file, pick the sheet you want, check the preview and press Download CSV. The file is created on your device.
Can I convert all sheets in a workbook?
CSV holds one sheet per file. Use Download every sheet to get one CSV for each sheet, or choose a sheet and download them one at a time.
Why do accents or symbols look wrong in Excel?
Turn on the UTF-8 BOM option. It tells Excel to read the CSV as UTF-8 so accents, symbols and non-English letters show correctly.
What happens to formulas?
The CSV stores the value that the cell shows, not the formula. Dates and numbers appear in the format they have in the sheet.
Is my spreadsheet uploaded anywhere?
No. The file is read and converted in your browser. Only the open-source reader library is downloaded from a public CDN.
