JSON to CSV Converter

Why convert JSON to CSV?
JSON is what APIs speak; CSV is what spreadsheets, analysts and import wizards understand. Converting a JSON array of objects to CSV turns API data into something Excel, Google Sheets or any BI tool opens directly.
Every unique key across the objects becomes a column header and each object becomes a row. Values containing commas or quotes are escaped according to the CSV standard (RFC 4180), so the file opens correctly everywhere.
