Frequently asked questions

Is my CSV uploaded to a server?

No. Parsing and conversion happen entirely in your browser. Nothing is sent or stored — safe even for sensitive spreadsheets.

Does it handle quoted fields with commas inside?

Yes. The parser follows the CSV standard (RFC 4180): quoted fields can contain commas, double quotes and even line breaks.

Can I convert semicolon- or tab-separated files?

Yes — the delimiter is auto-detected, and you can switch it manually between comma, semicolon and tab.

Can numbers stay numbers instead of strings?

Enable “Convert numbers” and numeric values are emitted as JSON numbers instead of quoted strings.
