They need to be flattened into columns. A common approach is dot notation such as `user.address.city`.

Frequently Asked Questions
What happens when records contain different keys?
The output may contain columns for the available keys, with empty cells where a particular record does not contain a value.
Can every JSON document be converted cleanly to CSV?
No. CSV is inherently tabular, so highly nested structures or arrays of varying shapes may require decisions about how the data should be flattened.
