Frequently Asked Questions
The converter supports JSON arrays of objects — e.g.
[{"name":"Alice"},{"name":"Bob"}]. Each object becomes a CSV row. A plain JSON object or other formats are not supported directly.Nested objects and arrays are stringified as JSON in the CSV cell. If you need them flattened, manually flatten your JSON first or use a tool like jq.
Use comma for standard CSV (works in most tools). Use semicolon if you're opening in European versions of Excel. Use tab for TSV files, which avoid issues with commas inside data values.
Completely. All conversion happens in your browser. Nothing is uploaded to any server. You can disconnect from the internet and this tool still works.
