JSON to CSV Converter

Use this endpoint when you have a JSON array of flat or semi-flat objects and need to produce CSV output quickly without setting up a local parser. Ideal for agents that receive JSON from upstream APIs and need to pass tabular data to downstream tools, spreadsheet applications, or bulk-import systems that only accept CSV. Prefer this over a local conversion when operating in a stateless pipeline and the $0.01 per-call cost is acceptable.

• Input is not a valid JSON array — returns an error if the string is malformed JSON or is a JSON object instead of an array
• Input array contains heterogeneous objects with inconsistent keys — may produce misaligned columns or missing values
• Empty array input — may return only headers or an empty response
• Non-serializable values (nested objects, arrays) may be stringified or dropped rather than flattened
