Paste your JSON array into the input field and ToolsStack automatically converts it to CSV format. Nested objects are flattened into dot-notation column headers (e.g., "address.city"). You can then copy or download the CSV output.
Nested objects are automatically flattened using dot-notation. For example, {"user": {"name": "John"}} becomes a column named "user.name" with the value "John". Arrays within objects are stringified.
Yes. All conversion happens client-side in your browser. Your JSON data is never uploaded to any server or stored anywhere — it stays entirely on your device.
