FAQ
Q: What if a field contains a comma?
Wrap the field in double quotes, e.g. "Zhang, San". The parser correctly recognizes commas inside quotes and will not treat them as delimiters.
Q: Is content uploaded to the server?
No. All conversion happens in your browser. Content never leaves your device, fully protecting your privacy.
