CSV to Excel Converter — free online

You got a CSV file from somewhere, but you really need it as a proper Excel spreadsheet. Maybe a coworker asked for an .xlsx, or you just want to open it cleanly without that messy comma view. We added a free tool that does it — CSV to Excel Converter — right in your browser.

What it does

It takes your CSV file and turns it into a real Excel (.xlsx) file. No sign-up, no watermark on the result. You drop in the CSV, and you get back a clean spreadsheet you can open in Excel, Numbers, or Google Sheets.

Nothing leaves your device

The whole thing runs inside your browser. Your file is never uploaded to a server and nothing is saved anywhere. When you close the tab, it's gone. So even a private list of names or numbers stays only with you.

How to use it

  1. Open CSV to Excel Converter and pick your CSV file.
  2. Let it convert the data into a spreadsheet.
  3. Download the .xlsx file and open it wherever you like.

It's free with no limit. There are more small tools on the Apps page.
