Questions

How big a Parquet file can it open?

Files of a few hundred megabytes work on most computers. Very large tables may be too big for Excel, which stops at 1,048,576 rows; use CSV for those.

Are my files uploaded?

No. Everything happens inside your browser, on your own device. The site's security settings stop the page from sending your files anywhere.

Is it free?

Yes. No sign-up, no daily limit and no watermark.

Does it work on iPhone and Android?

Yes, in Safari, Chrome and other modern browsers. You can open files from the Files app or your downloads, and save the results back.

Know someone who'd find this handy?

Send the link to a friend or colleague. It's free for them too, with no sign-up.

Other converters upload your files. This one can't.

Customer lists, contacts, bank exports and the routes you run from home stay on your phone or computer from start to finish.
