Why convert CSV to Excel?
To convert CSV files to Excel, drop them on the counter above. CSV is plain text: no formatting, formulas or multiple sheets, and accented characters can break in Excel. Excel, Google Sheets and LibreOffice open XLSX, and you can add formulas, formatting and more sheets.
Most files convert in seconds: no queue, no email address, and the XLSX result saves straight to your computer or phone.

Frequently asked questions
Is converting CSV to Excel free?
Yes, completely free. No account, no daily limit, no watermark and no queue.
Does it work on a phone?
