Yes. Nested objects are flattened with dot notation. {"user":{"name":"John"}} becomes a column named "user.name". Arrays are comma-separated.
What JSON structure works for CSV export?
Arrays of objects work best: [{"name":"A"},{"name":"B"}]. Single objects become one-row CSVs. Complex nesting is flattened.
