What if different objects have different fields?

The CSV header includes every field found across all objects; any object missing a given field gets an empty cell for that column.

How are nested objects or arrays inside a field handled?

Nested values are serialized back to a JSON string within that CSV cell, since CSV itself has no concept of nested structure.
