YAML to JSON

Convert YAML (or YML) documents into JSON for APIs, tests, and debugging. Paste config files, Kubernetes manifests, or CI snippets and get indented JSON instantly.

How it works

1. Paste YAML source in the input area.
2. Click Convert to parse and pretty-print JSON.
3. Copy the result or share the page link.

When to use it

• Inspect Helm or Docker Compose values as JSON
• Feed YAML fixtures into JSON-first unit tests
• Debug parsing issues before deploying configs

Limitations

Parsing runs entirely in your browser. Very large files are held in memory only. Invalid YAML returns an error without partial output.

Example

YAML:

service:
  name: api
  replicas: 2

converts to pretty-printed JSON {"service":{"name":"api","replicas":2}} (exact key order may follow the parser). Invalid indentation or duplicate keys surface as a parse error instead of a partial object.

This skill is available over A2A JSON-RPC and REST. When you already know the skill id and export, call execute directly—no discovery step required.

REST example

curl -sS -X POST https://toolplaza.app/api/helpers/execute \
  -H 'Content-Type: application/json' \
  -d '{"skillId":"yaml__to-json","export":"fromYamlToJson","args":["Hello"]}'

A2A JSON-RPC example

Send POST https://toolplaza.app/api/a2a with:

{
  "jsonrpc": "2.0",
  "id": "1",
  "method": "message/send",
  "params": {
    "message": {
      "messageId": "uuid",
      "role": "user",
      "parts": [
        {
          "kind": "text",
          "text": "ignored"
        }
      ]
    },
    "metadata": {
      "toolplaza": {
        "skillId": "yaml__to-json",
        "export": "fromYamlToJson",
        "args": [
          "Hello"
        ]
      }
    }
  }
}
