What JSON format is required?

The input must be a valid JSON array of objects, e.g. [{"name":"Alice","age":30},{"name":"Bob","age":25}]. All objects should share similar keys.

How does nested object handling work?

Nested objects can be flattened using dot notation (e.g., address.city) or displayed as a compact JSON string in a single cell.

Can I transpose the table?

Yes! The transpose button swaps rows and columns, turning column headers into row labels and vice versa.

How do I export to CSV?

Click the 'Download CSV' button after converting. The CSV uses the same column structure as the generated table.

Does it handle missing keys?

Yes. If some objects are missing certain keys, those cells will appear empty in the table.
