常见问题
Is my input sent to a server?
No. Everything runs locally in your browser — your input is never uploaded, stored or logged.
Is the JSON validated first?
Yes — the input is parsed, so invalid JSON shows an error instead of producing broken output.
Is it really free?
Yes — free, with no signup and no limits.
