Free JSON to CSV Converter

What is this JSON to CSV converter?

Use this free converter to export JSON data into CSV for spreadsheets, reports, and data pipelines. It detects headers from object keys, handles arrays, and safely quotes values that include commas, quotes, or new lines. Choose a delimiter that matches your target system, then download or copy the result for quick use.

How to use it

1. Paste JSON or upload a .json file.
2. Select a delimiter (comma, semicolon, tab, or pipe) and optionally quote all fields.
3. Click Convert to generate CSV from arrays or objects.
4. Copy the CSV or download it as a .csv file.

Tips

• For arrays of objects, headers are inferred from the union of keys.
• Nested objects are flattened using dot notation; arrays inside fields are JSON-stringified.
• Use Tab delimiter to avoid conflicts with commas in the data.
