- Leave the separator on automatic, or choose comma, semicolon, tab or vertical bar.
- Click "Convert to Excel" to download the .xlsx file.
Frequently asked questions
Why do accents look wrong when I open a CSV in Excel?
Excel often guesses the wrong text encoding for CSV files. This tool reads UTF-8, UTF-16 and older Windows files correctly, so the Excel file shows every character as it should.
Are leading zeros kept?
Yes. Values such as 00412, phone numbers starting with + and long ID numbers stay text. Other numbers, amounts and percentages become numbers, so formulas work.
Can I combine several CSV files?
Yes. Add several files and each one becomes a sheet, named after the file, in a single Excel workbook.
Is my file uploaded?
No. The CSV is read and converted in your browser, so your data never leaves your device.
