YAML ⇄ JSON

Convert between YAML and JSON, with validation.

Why this exists

Kubernetes speaks YAML, APIs speak JSON, and much of DevOps is moving data between the two. Also the quickest way to find the indentation error a YAML parser is complaining about.

YAML → JSONIndent

YAML

JSON

{
  "services": {
    "web": {
      "image": "nginx:alpine",
      "ports": [
        "8080:80"
      ],
      "restart": "unless-stopped"
    }
  }
}

Merge keys (<<: *anchor) are resolved, and a multi-document stream becomes a JSON array. Under YAML 1.2 NO is the string “NO”, not false — you get a warning when that could bite.
