What JSON format does this accept?

An array of objects with consistent keys. Example: [{"name":"Alice","age":30},{"name":"Bob","age":25}].

Does it handle nested JSON?

Nested objects are flattened to string representations in CSV. For deeply nested data, consider flattening first.

Comma is standard (.csv). Use semicolon for European locales, tab for TSV format, pipe for data with commas in values.
