JSON to CSV Converter
Convert JSON arrays to CSV format instantly. Auto-detects headers from JSON keys. Also converts CSV back to JSON.
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.
