From JSON to XML

Transform a JSON object or array into equivalent XML markup with a predictable element nesting structure.

Mapping rules

• JSON objects become XML elements; each key is a tag name, each value is nested content or child elements.
• JSON arrays repeat elements or wrap items according to the converter’s array policy.
• Primitive values (strings, numbers, booleans, null) become text nodes or self-closing elements as appropriate.

Invalid JSON is rejected before conversion begins, preventing half-formed XML output.

When to use it

Bridge REST JSON APIs to legacy XML consumers, generate config snippets for enterprise systems, or inspect how hierarchical data looks in angle-bracket syntax.

Limitations

JSON keys that are not valid XML names may be escaped or altered. Attributes versus elements follow a fixed convention — not every schema’s preferred shape. Namespaces, CDATA sections, and mixed content models are not inferred automatically. Large payloads are limited by browser string size.

Example

Input {"b":2,"a":1} for from-json-to-xml yields a deterministic reformatted string unique to this converter.

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":"json-xml__from-json-to-xml","export":"fromJsonToXml","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": "json-xml__from-json-to-xml",
        "export": "fromJsonToXml",
        "args": [
          "Hello"
        ]
      }
    }
  }
}
