JSON ↔ CSV Converter
DeveloperNewInstantly convert a JSON array of objects to CSV with headers, or parse CSV (including quoted fields and embedded commas) back to a pretty JSON array.
Frequently asked questions
How do I convert a JSON array to a CSV file?
Paste a JSON array of objects, and the tool generates a CSV with column headers taken from the object keys and one row per array item. Switch direction to parse a CSV back into a pretty-printed JSON array.
Can I convert JSON with nested objects to CSV?
Yes. Nested JSON objects are automatically flattened into separate column headers during conversion, so hierarchical API data becomes compatible with the flat row and column structure CSV requires.
Does this tool handle CSV files with quoted fields and commas inside values?
Yes. The CSV parser correctly handles quoted fields, embedded commas, and escaped quotes within a field, so converting back to JSON preserves values that contain special characters.
What JSON structure does this converter expect?
The input for JSON to CSV must be a JSON array of objects, where each object represents one row. A single object or deeply mismatched keys across items will not convert into a clean table.
