What JSON format is supported?

How are nested objects handled?
Nested objects are flattened using dot notation. For example, {"address":{"city":"NYC"}} becomes a column named 'address.city'.
Can I open the CSV in Excel?
Yes, the output CSV file can be opened directly in Excel, Google Sheets, or any spreadsheet application.
