Frequently Asked Questions

What delimiter is supported?

We support comma (,) as the delimiter. Make sure your first row contains column headers.

How is the CSV structured?

The first row should contain headers, and each subsequent row becomes a JSON object with those headers as keys.

Is my data private?

Yes! All conversion happens in your browser. No data is sent to any server.

Can I convert large CSV files?

Yes, but very large files may take longer to process depending on your device's performance.
