What this tool is for
Use this tool when you need to turn valid JSON into CSV that opens cleanly in spreadsheets, exports, or import flows. Everything runs locally in the browser.
Where it helps
- Turning arrays of JSON objects into rows that analysts or operations teams can open in spreadsheet tools.
- Tuning delimiters, quotes, header rows, and formula escaping before sharing a CSV export.
- Preparing lightweight tabular output for systems that accept CSV but not raw JSON.
What to watch for
- Input must be valid JSON in this tool.
- Arrays of objects work best when you want named CSV columns, while arrays of arrays can be useful for raw row output.
- If you need the reverse direction, use the CSV to JSON converter instead.
