Convert JSON to CSV
Paste a JSON array of objects on the left, get CSV on the right — keys become headers automatically.
Headers are the union of keys across all rows; missing keys become empty cells. Nested objects and arrays are serialized as JSON strings inside cells. A single object (not wrapped in an array) is treated as one row. All processing happens locally in your browser.
