Frequently Asked Questions

How are nested JSON objects handled?

Nested objects are automatically flattened using dot notation. For example, {"user": {"name": "Alice"}} becomes a column "user.name" with value "Alice".

Can I convert CSV back to JSON?

Yes. Switch to CSV to JSON mode, paste your CSV with headers in the first row, and each row becomes a JSON object with header names as keys.

Is my data sent to a server?

No. All conversion happens entirely in your browser. Your data never leaves your device.
