Frequently asked questions

What format does my JSON need to be in?
An array of flat objects. Each object becomes one row, and the union of all keys becomes the column headers.
How are nested objects handled?
Nested objects and arrays are JSON-stringified into a single CSV cell. For best results, flatten your data before converting.
Will the CSV open in Excel?
Yes — the output uses standard CSV with proper escaping for commas, quotes and newlines, compatible with Excel, Google Sheets and Numbers.
