Pretty-print JSON

Pretty-print JSON by parsing your input and re-serializing it with two-space indentation. Ideal when reading minified API responses, single-line config exports, or compressed log lines.

When to use it

• Inspect nested objects from REST or GraphQL responses
• Prepare readable JSON for code reviews or documentation
• Verify that a string is valid JSON before committing to a repo

Limitations

Key order follows JavaScript object enumeration after parse—it may differ from the original file. Very large documents are processed entirely in memory in your browser. Invalid JSON returns an error message instead of partial output.

Example

Minified input {"user":{"id":7,"name":"Ada"},"ok":true} pretty-prints with two-space indentation so nested objects and arrays are easy to scan:

{
  "user": {
    "id": 7,
    "name": "Ada"
  },
  "ok": true
}

Invalid JSON returns an error instead of a partial tree, which helps catch typos before you commit a config file.

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":"formatter__json-pretty","export":"prettyPrintJson","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": "formatter__json-pretty",
        "export": "prettyPrintJson",
        "args": [
          "Hello"
        ]
      }
    }
  }
}
