|---|---|---|
| "Senior Engineer" | Senior Engineer | Clean strings written without extra quotes |
| "London, UK" | "London, UK" | Values containing commas wrapped in double quotes |

Frequently Asked Questions about JSON to CSV Converter (Export JSON Arrays to Spreadsheet)
What JSON format is required for JSON to CSV conversion?
Provide a valid JSON array of objects (for example, `[{"id": 1, "name": "Alice"}, {"id": 2, "name": "Bob"}]`). The keys of the objects are automatically extracted as the first row of CSV column headers.

Yes. Once you click 'Convert Now', click the 'Table' toggle at the top-right of the output panel to view your converted CSV in a clean spreadsheet grid.
