Common questions
Does CSV need a header row?
For CSV to JSON conversion, a header row is strongly recommended because it becomes the JSON field names.
What JSON format works best for CSV output?
An array of objects works best because CSV is a row-and-column format.
What if a CSV field contains a comma?
Valid CSV wraps that field in quotes so the comma is not treated as a separator.
