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
- Open CSV to Excel Converter and pick your CSV file.
- Let it convert the data into a spreadsheet.
- 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.
