Excel to CSV Converter — free online

You have a spreadsheet in Excel, but the thing you want to import it into only takes CSV. Saving it the long way means opening Excel, picking the right "Save as" option, and hoping you didn't mangle a column. We added a free tool that does it for you — Excel to CSV Converter — right in your browser.

What it does

It opens an Excel .xlsx file and turns it into a plain CSV. You pick which sheet you want and choose how it's written, then you get a clean CSV file back. No account, no sign-up — just drop the file in and convert.

Nothing leaves your device

The whole thing runs inside your browser. Your spreadsheet isn't uploaded to a server and nothing is saved anywhere. When you close the tab, it's gone. So even a file with private numbers in it stays on your own computer.

How to use it

1. Open Excel to CSV Converter and add your Excel .xlsx file.
2. Pick the sheet you want and choose how the CSV is written.
3. Download the CSV and use it wherever you need it.

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