What does JSON to CSV do?

JSON to CSV converts JSON arrays into comma-separated values format, making JSON data compatible with spreadsheet applications like Excel and Google Sheets. Each JSON object in the array becomes a row, and each key becomes a column header.

Does it handle nested JSON?

The converter flattens one level of nesting. For deeply nested JSON structures, nested objects are serialised as string representations in the CSV cells. For complex nested data, you may need to pre-process the JSON before converting.

Is the converter free?

Yes — completely free, runs entirely in your browser, no data is sent to any server, no signup required.

Frequently Asked Questions

What JSON format does this support?

Arrays of objects — the most common API response format. Each object should have the same keys which become the CSV column headers. Nested objects are flattened with dot notation.

How are special characters handled?

Values containing commas, quotes or newlines are automatically wrapped in double quotes per RFC 4180. Existing double quotes are escaped as two consecutive double quotes.

Can I convert back from CSV to JSON?

Yes — use the CSV → JSON tab. The first row is treated as headers and each subsequent row becomes a JSON object.
