Questions

Do my files get uploaded?

No. FileFleet runs entirely in your browser, so your files never leave your device. Close the tab and they're gone.

Is it really free?

Yes. No account, no daily limits and no watermark on your files.

What if my CSV has no header row?

Untick “First row is a header” and each row becomes a list of values instead.
