Frequently asked questions
- Are my files uploaded to a server?
- No. This tool runs entirely in your browser using JavaScript — your files never leave your device.
- How are CSV headers handled?
- With 'First row is headers' ticked, each row becomes a JSON object keyed by the header names. Untick it to get plain arrays instead.
- Does it handle quoted fields?
- Yes — quoted fields with embedded commas, quotes and line breaks are parsed correctly (RFC 4180 style), and comma, semicolon and tab delimiters are auto-detected.
