FAQ
What JSON format is supported?
JSON must be an array of objects, e.g. [{"name":"Alice","age":30},...]. Object keys become CSV column headers.
What about CSV format?
The first row must be column headers. Subsequent rows are data. Fields containing commas or quotes are handled automatically.
Does it support nested JSON?
Nested JSON objects are converted to string representation in CSV cells. For complex structures, use the JSON formatter first.
