Common issues & tips
- •JSON input must be a valid array of objects (e.g. [ { ... }, { ... } ]). Single primitive values cannot be converted to tabular CSV.
- •Nested JSON objects or arrays are stringified into JSON substrings within their CSV cell.
Frequently asked questions
- What structure does the JSON input need?
- Input should be a valid JSON array of objects, e.g. [ { "name": "Alice", "age": 30 }, { "name": "Bob", "age": 25 } ].
- Is my data sent to a server?
- No. Parsing and CSV generation happen entirely in your browser.
