YAML ↔ JSON Converter

YAML (YAML Ain't Markup Language) and JSON (JavaScript Object Notation) are both human-readable data serialization formats, but they serve different use cases. JSON is strict, unambiguous, and universally supported -- every programming language can parse it. YAML is a superset of JSON (YAML 1.2), adding support for comments, multi-line strings, anchors, and aliases. YAML is preferred for configuration files (Kubernetes, Docker Compose, GitHub Actions, Ansible) while JSON is preferred for API responses and data exchange. This converter translates between the two formats instantly, making it easy to migrate configurations or debug data structures.
