The tool expects a JSON array of objects, where each object represents a row. For example: [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}].

How are nested objects handled?

Nested objects are flattened using dot notation. For example, {"address": {"city": "NYC"}} becomes a column named "address.city".
