CSV to Excel

Turn a CSV file into a real Excel workbook (.xlsx) without uploading anything.

100% private — everything runs in your browser

How to Use

  1. 1

    Drop a CSV file — it is parsed in your browser and never uploaded.

  2. 2

    Check the delimiter and the preview so columns line up correctly.

  3. 3

    Download the .xlsx workbook and open it in Excel, Numbers or Google Sheets.

FAQ

Is my CSV uploaded to a server?

No. Parsing and workbook generation both run locally in your browser.

Will leading zeros be removed?

No. Cells are stored as text, so values like 007 or long account numbers keep their exact form.

Which delimiters are supported?

Comma, semicolon and tab. Pick one manually if auto-detection guesses wrong.
