What XML to JSON Converter does, with a checked example

XML and JSON model documents differently, so conversion requires explicit conventions. This tool parses elements, text, repeated child elements, and attributes into a JavaScript object before serializing it as JSON. Attributes use an @_ prefix and mixed text uses #text so those values are not confused with child elements.

Worked example

A concrete input and expected output from the current implementation.

Input

<note id="7"><to>Bee</to><priority>high</priority></note>

Expected output

{
  "note": {
    "@_id": "7",
    "to": "Bee",
    "priority": "high"
  }
}

The id attribute is kept separately from child elements. Each child appears once, so its value is represented directly instead of as an array.

How the result is produced

1

Repeated elements become arrays

When siblings share a tag name, their converted values are collected in document order. A single child remains a scalar or object, which keeps common output compact.

2

This is a lightweight parser

Elements, attributes, comments, CDATA, common entities, and basic declarations are handled. Advanced namespace processing, DTD validation, and full XML Schema validation are outside its scope.

Good uses

  • Inspect a small configuration or export file in JSON form.
  • Prototype a mapping before writing production conversion code.
  • Turn a repeated XML list into data that is easier to browse.

Limits and checks

  • XML attributes are strings even when they look numeric or Boolean.
  • Mixed-content documents may require application-specific ordering rules.
  • Validate important source documents with a full XML parser before migration.

Common questions

Is there one official XML-to-JSON mapping?

No. XML has attributes, namespaces, mixed content, and ordering rules that do not map uniquely to JSON. Always document the convention used by a converter.

Why did one element become an array?

The same child tag appeared more than once under its parent. The array preserves every occurrence and its order.
