From XML to JSON

Parse XML documents and emit a readable JSON representation for APIs, log analysis, and configuration tooling.

Transformation approach

The parser walks the XML DOM tree and maps elements to JSON objects. Repeated sibling tags typically become arrays; leaf nodes with only text content collapse to string values. Attributes can be collected into dedicated keys depending on the converter settings.

Malformed XML (unclosed tags, invalid entities) fails parsing with an error instead of producing partial JSON.

When to use it

Inspect SOAP responses, migrate legacy XML configs to JSON-first stacks, or quickly pretty-print hierarchical data for debugging.

Limitations

XML features such as namespaces, xsi:type hints, and mixed element/text content may not round-trip perfectly to JSON and back. Very large documents can stress browser memory. The converter favors structure over preserving original attribute ordering or comments.

Example

Input {"b":2,"a":1} for from-xml-to-json 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-xml-to-json","export":"fromXmlToJson","args":["<root><key>value</key></root>"]}'
