Frequently asked questions
What JSON shape works best?
An array of flat objects with consistent keys converts most cleanly, for example [{"name":"...","email":"..."}, ...].
What happens with nested objects inside the JSON?
Nested objects are flattened into dot-notated column names where possible, since CSV has no native concept of nesting.
What if some objects are missing certain keys?
Missing keys produce an empty cell in that row’s corresponding column.
