FAQ
Can I convert a single JSON object (not an array)?
The tool requires a JSON array. You can wrap a single object in square brackets like [yourObject] to convert it.
How are nested objects handled?
Nested objects and arrays are converted to their string representation in the CSV output. For deeply nested data, consider flattening the structure first.
