Frequently Asked Questions

Is my data uploaded when I convert it?

No. CSV parsing, JSON conversion, and delimiter detection all run in your browser. Your data never leaves your device.

Which delimiters are supported?

Comma, semicolon, and tab. The Detect button guesses the delimiter from the first line, and you can switch manually if the guess is wrong.

Does the converter handle quoted fields?

Yes. Parsing follows RFC 4180 conventions: quoted fields, escaped double quotes, and embedded delimiters or newlines inside quotes are supported.
