About this tool

CSV looks simple until a field contains a comma, a quote or a line break. This converter uses a proper CSV parser that understands quoted fields and doubled quotes, so "Ada, A." stays one field. Values are returned as strings — CSV has no types, and guessing which "007" is a number and which is a code causes more harm than good. An unterminated quote is reported as an error.
