FAQ

Does it handle nested JSON?

The converter produces a flat array of objects — one object per row, headers as keys. For nested structures, you'd need to transform the output.

What about special characters and quotes?

Fully handled. Escaped quotes, commas inside fields, multiline values — all parsed correctly per RFC 4180.

Is my data uploaded?

No. Everything runs in your browser. Your file never leaves your device.
