Data format converters
Format converters let you move data between serialization formats without writing code. The most common are JSON↔YAML (for switching between API responses and config files), XML↔JSON (for legacy integrations), and CSV↔JSON (for spreadsheet data ingestion). All converters preserve nested structures and data types.
