About JSON to CSV conversion

This converter takes a JSON array of objects and produces a CSV file where the first row contains headers (the object keys) and subsequent rows contain the values. It handles proper CSV escaping — values containing commas, quotes, or newlines are wrapped in double quotes with any internal quotes doubled.
