XML / JSON Converter

Online XML to JSON Converter | Fast & Lossless Format Conversion | ToolOrbit

The XML / JSON Converter performs bidirectional conversion between XML document structures and JSON data structures. It is suitable for SOAP/XML-RPC API responses, RSS feeds, XML Sitemaps, SVG vector markup, Android layout files, JSON configurations, and API response bodies. When HTML source is pasted, the tool outputs a readable JSON representation of the document structure.

How to convert XML and JSON safely

1Paste the source payload into the editor and confirm whether you are converting XML to JSON or JSON to XML before running the conversion.
2Keep sample data representative of the real API response, including nested objects, arrays, attributes, and empty values, so the output structure is useful for implementation.
3After conversion, inspect attributes, repeated nodes, and numeric-looking strings. XML and JSON model data differently, so some structures need a human check before production use.
4Copy the result into your API docs, tests, or migration notes, then validate it again with the receiving system if strict schemas are involved.

Input

In XML → JSON mode, provide a standard XML document, HTML page source, or XML fragment (e.g. <root><item id="1">Hello</item></root>). In JSON → XML mode, provide a valid JSON object string, and the tool will serialize it into equivalent XML markup.

Output

In XML → JSON mode, the output is a compact JSON object where XML attributes are mapped to _attributes keys, text nodes are mapped to _text keys, and child elements are nested as same-name properties. When pasting HTML source, the output includes a complete DOM JSON tree with documentType and root nodes. In JSON → XML mode, the output is readable XML text with 2-space indentation.

How it works

For XML to JSON, the tool preserves element, attribute, and text-node hierarchy. For JSON to XML, it first checks that the JSON is valid, then generates the corresponding XML markup. Conversion runs locally and input content is not uploaded.

XML to JSON conversion example

Input example

<catalog>
  <book id="bk101">
    <title>XML Guide</title>
    <price>44.95</price>
  </book>
  <book id="bk102">
    <title>JSON Guide</title>
    <price>39.95</price>
  </book>
</catalog>

Output example

{
  "catalog": {
    "book": [
      {
        "_attributes": { "id": "bk101" },
        "title": { "_text": "XML Guide" },
        "price": { "_text": "44.95" }
      },
      {
        "_attributes": { "id": "bk102" },
        "title": { "_text": "JSON Guide" },
        "price": { "_text": "39.95" }
      }
    ]
  }
}

Why use this XML JSON converter?

Two-way conversionMove between XML and JSON when documenting APIs, building adapters, or preparing test fixtures.
Nested data supportPreserve useful structure for common arrays, objects, repeated nodes, and attribute-style data.
Developer review friendlyImmediate output makes it easy to inspect schema assumptions before putting converted data into code.

Frequently Asked Questions

Why do XML attributes look different after conversion?

XML allows attributes and child nodes on the same element, while JSON only has key-value structures. Converters usually map attributes to special keys or nested properties, so review attribute-heavy XML carefully.

Can this converter handle deeply nested payloads?

It is designed for practical API payloads and configuration snippets with nested objects and arrays. Extremely large files may slow the browser, so split huge exports into smaller samples when possible.

Is converted data uploaded to a server?

No. The conversion runs in the browser, which is useful for private API examples, internal test fixtures, and draft integration notes.
