Frequently Asked Questions

Does it handle nested objects?

Yes. Nested object keys are flattened with dot notation (e.g., user.name, address.city). Arrays inside objects are JSON-stringified into a single cell.

How are CSV special characters escaped?

Fields containing the delimiter, quotes, or newlines are wrapped in double quotes. Embedded double quotes are escaped as "" per RFC 4180.
