JSON to CSV

FAQ

What JSON shapes work for CSV export?+

Arrays of objects are ideal. A single object becomes one row. Nested objects and arrays flatten into dot-separated column names.

Does CSV conversion change my JSON values?+

Values stay the same where CSV can represent them. Nested structure is flattened to columns; convert CSV back to JSON to rebuild nesting.

Can I open the output in Excel?+

Yes. Download the CSV file and open it in Excel, Google Sheets, or any CSV-aware tool.

Is my data uploaded?+

No. Conversion runs locally in your browser. Nothing is sent to a server.

What delimiter does the CSV use?+

Comma-separated values with standard double-quote escaping. Fields containing commas or quotes are wrapped in quotes per typical CSV conventions.
