Frequently asked questions
- Is my data uploaded?
- No. Parsing and conversion happen locally in your browser, so it suits sample data with sensitive fields.
- Can nested JSON be restored losslessly after converting to CSV?
- No. Nested objects are flattened with a dot (for example `user.name`), so converting back yields flat keys (`{"user.name":"John"}`) that cannot be turned into nested objects automatically.
- How are CSV fields that contain commas handled?
- Wrap the field in double quotes and escape any double quotes inside it as `""`. This tool parses in the RFC 4180 style.
- Does it switch the conversion direction automatically?
- No. You pick the direction yourself; if the input looks like JSON or CSV, the page only suggests a switch.
