Pick a sheet from an .xlsx or .xls Excel file and convert it to CSV format. You can choose a comma, semicolon, tab, or pipe delimiter, and download a CSV with a UTF-8 BOM so non-Latin characters don't come out garbled.
How to use
- Drag and drop or click to select an Excel (.xlsx/.xls) file.
- Select the sheet to convert and the delimiter (comma/semicolon/tab/pipe).
- Check the preview, then save the file with 'Download CSV' or copy it with 'Copy CSV'.
FAQ
- Characters look garbled when I open a CSV in Excel—is that a problem here?
- The downloaded CSV includes a UTF-8 BOM, so characters display correctly even when you open it directly in Excel.
- Can I change the delimiter?
- Yes. You can choose a comma (,), semicolon (;), tab, or pipe (|), which is handy when your locale requires a semicolon-delimited CSV.
- Is my file sent to a server?
- No. The Excel file you upload is never sent to or stored on a server, and the CSV conversion happens entirely within your browser.
