JSON ↔ YAML Converter
Convert between JSON and YAML formats. Paste your data, choose a direction, and get formatted output instantly.
JSON vs YAML
JSON (JavaScript Object Notation) is the standard format for APIs — compact, machine-readable, and widely supported. YAML (YAML Ain't Markup Language) is used in config files like Docker Compose, Kubernetes manifests, and CI/CD pipelines — it's more readable but whitespace-sensitive.
YAML is a superset of JSON, so any valid JSON is valid YAML. This tool converts between the two using the js-yaml library.
