Frequently Asked Questions
How are nested objects handled?
Nested objects are flattened using dot-notation. For example, {"user": {"name": "Alice"}} becomes a column "user.name" with value "Alice".
Does the input need to be an array?
Yes. The JSON input must be an array of objects. Each object becomes one row, and object keys become column headers.
