How do I convert JSON to CSV online?

Paste a JSON array of objects with consistent keys—each object becomes a row, keys become column headers. Nested objects may flatten to dotted paths or require preprocessing. Download CSV for Excel or Google Sheets. Validate JSON first with JSON Formatter when the source is minified or malformed.
