About CSV to XLSX conversion
Your CSV is parsed and written into a real Excel workbook, ready to open with formatting intact. Exports from any system — banking, analytics, shop orders — convert in a click.
How to convert CSV to XLSX
- Drop your CSV files onto the box above, or click Choose files.
- The output format is already set to XLSX — adjust it per file if you need something else.
- Click Convert, then download your XLSX 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.
