Frequently Asked Questions
What JSON formats are supported?▼
The converter expects a JSON array of objects. Each object becomes a row in the CSV, and the keys become column headers. Nested objects are flattened using dot notation (e.g., 'address.city').
Can I convert nested JSON?▼
Yes, nested objects are automatically flattened. For example, {"user": {"name": "John"}} becomes a column header 'user.name' with value 'John'.
