The tool expects a JSON array of objects, where each object represents a row. Example: [{"name":"Alice","age":30},{"name":"Bob","age":25}]. All objects should share the same keys for best results.
Nested objects are flattened using dot notation. For example, {"address":{"city":"NYC"}} becomes a column called "address.city". Arrays within objects are converted to a JSON string in that cell.
