The JSON to CSV Converter takes a JSON array of objects (or a single object) and produces a delimited CSV file with auto-detected headers from object keys. Useful for data analysts pulling JSON from APIs into Excel, Google Sheets, or pandas. Handles nested objects (flattened with dot notation), arrays (joined with semicolon), null/undefined (empty cell), and configurable delimiters (comma, semicolon, tab).
