Question 1

What JSON structure is required?

Accepted Answer

The converter expects a JSON array of flat objects — for example, [{"name":"Alice","age":30}]. Each object becomes one CSV row. If you pass a single object, it's wrapped in an array automatically.

Question 2

How are nested objects handled?

Accepted Answer

Nested objects and arrays within JSON values are serialized as JSON strings within the CSV cell, quoted properly per RFC 4180 so they don't break the CSV structure.

Question 3

How are commas and special characters escaped?

Accepted Answer

Any CSV field containing a comma, newline, or double-quote is automatically wrapped in double quotes. Double-quote characters within values are escaped by doubling them ('""'), following the RFC 4180 standard.
