Which data formats are supported?

CSV, TSV and JSON, convert between any of the three.

Will converting change how my data is structured?

CSV and TSV are flat tables while JSON can be nested; converting between them maps as directly as the formats allow, deeply nested JSON may flatten during conversion.

Can it handle large files?

Yes, though very large files will take longer since conversion happens entirely in your browser.

Does File Converter upload my files to a server?

No. File Converter runs entirely in your browser using on-device processing, your files never leave your device.
