About XLSX to CSV conversion
The first sheet of your workbook is exported to standards-compliant CSV with proper quoting. Since nothing is uploaded, customer lists and financials stay on your machine.
Good to know: Multi-sheet workbooks: the first sheet is converted. Formulas are exported as their calculated values.
How to convert XLSX to CSV
- Drop your XLSX files onto the box above, or click Choose files.
- The output format is already set to CSV — adjust it per file if you need something else.
- Click Convert, then download your CSV files (or everything as one ZIP).
Free, no account, no watermarks — and because the conversion runs in your browser, your files are never uploaded to a server.
