Frequently Asked Questions
Does it handle headers automatically?
Yep. If your CSV has a header row, it uses those as the JSON keys. If there's no header, it'll either generate generic keys or let you specify them. You can also tell it to skip the header row if needed.
What about different delimiters?
The tool tries to detect whether you're using commas, semicolons, tabs, or pipes automatically. If it guesses wrong, you can manually pick the delimiter in settings. Useful if your data has commas inside the fields and uses semicolons instead.
How does it handle quoted fields?
CSV fields wrapped in quotes get handled properly. So if you have something like `"Smith, John"` in your CSV, it won't split on that comma—it knows it's one field. Same with newlines inside quoted fields.
Does my CSV get uploaded?
No. Everything runs locally in your browser. Your CSV file stays on your computer—nothing gets sent to a server.
