When to use it

  • Convert Helm or Kubernetes snippets to JSON for API testing
  • Transform YAML configs before storing in JSON-only systems
  • Debug user-submitted YAML by viewing it as JSON

Tips

  • Validate YAML first to avoid conversion errors
  • Redact secrets before converting and sharing output

Examples

Basic config

  • name: api -> { "name": "api" }

Invalid YAML

  • name api -> missing ':' flagged

FAQs

Does it support anchors/aliases?
Basic YAML features are supported; complex anchors may flatten in JSON output.
Is schema validation included?
