Turn your Excel data into CSV in one click. The file is processed in your browser and isn't uploaded to any server.
No sign-up and nothing uploaded to a server: everything happens in your browser. See for yourself.
No. Everything is processed inside your browser, and your files never leave your device.
There's no fixed limit. Sheets with hundreds of thousands of rows can be slow or use a lot of memory; use a computer for those.
The values are converted. Formulas are saved with their result, and visual formatting is lost.
Export the first sheet of your Excel workbook to CSV, the most compatible format for importing data into other systems.
Because everything happens on your device, you can convert customer lists, payrolls or inventories without exposing them on the internet.
If your workbook has several sheets, the first one is converted.
