FAQ
CSV ↔ JSON Converter questions.
Does the converter support quoted CSV values?
Yes. It uses a full CSV parser, so quoted commas, escaped quotes, delimiters, and multiline cells are handled correctly.
Can I convert a JSON object instead of an array?
Yes. A single JSON object is exported as one CSV row, while arrays of objects or arrays become multiple rows.
