JSON ↔ YAML 変換

Convert JSON to YAML and vice-versa. Useful for config files and Kubernetes manifests.

このツールについて

The JSON to YAML converter translates between the two most popular data-serialization formats. Useful for Kubernetes manifests, GitHub Actions, and any config-file workflow.

  • Bidirectional (JSON ↔ YAML)
  • Preserves types: numbers, booleans, nulls, strings
  • Indentation: 2 or 4 spaces
  • 100% browser-side — your data never leaves your device
