FAQ

What JSON structure does this expect?
An array of objects, like [{"name":"Ada"},{"name":"Grace"}]. A single object or an array of primitives can't become CSV rows, and you'll get a clear message explaining why instead of a silently wrong result.
What happens to nested objects or arrays inside a field?
They're serialized as compact JSON text inside that cell, rather than being flattened unpredictably or dropped. That keeps the data recoverable even though CSV itself has no concept of nesting.
