JSON ↔ YAML Converter

Convert between JSON and YAML

JSON and YAML describe the same data structures – just in different notations. The converter works both ways and validates the syntax. Handy for Docker Compose, Kubernetes, GitHub Actions and other configs.

• JSON → YAML: Compact JSON becomes readable, indented YAML.
• YAML → JSON: YAML is output as cleanly formatted JSON.
• Validation: Invalid input is shown with a precise error message.
