Conversor de XML a JSON

Pega un documento XML — un feed RSS, un manifiesto de aplicación web, un sobre SOAP, una configuración de Spring, un archivo OpenAPI / Swagger, un sitemap, o cualquier otro fragmento similar a SAX — y la herramienta lo convierte a JSON siguiendo un mapeo documentado: los atributos van bajo claves con prefijo @, los hermanos repetidos se convierten en arrays, el texto mezclado con hijos usa una clave #text para la parte de texto, y las secciones CDATA se fusionan con el texto del padre. En vivo, en el navegador, sin subir datos.

About this tool

XML to JSON converts any well-formed XML document into JSON in your browser. The mapping rules are documented and configurable: attributes become @-prefixed keys (toggleable), repeated sibling elements become arrays, mixed text-and-element content is split into #text and #children, CDATA sections are merged with the parent text, and XML declarations and DOCTYPEs are dropped or surfaced in a side panel. Comments and processing instructions are stripped by default with an option to preserve them under a #comment key. The output can be pretty-printed with a chosen indent, downloaded as a .json file, or browsed as a dot-path tree.

When to use it

  • Converting an XML API response (SOAP, RSS, Sitemap, Maven pom) to JSON for a JavaScript client
  • Inspecting the shape of an XML document before writing a parser for it
  • Comparing two XML payloads by converting both to JSON and diffing the JSON
  • Pasting an SVG path or a kml file to inspect its structure as a tree

When not to use it

  • You need a lossless round-trip — JSON cannot represent XML namespaces, mixed content order, and processing instructions in full fidelity. This tool produces a useful, conventional mapping; it does not preserve every detail
  • You need to convert JSON back to XML — that is a different operation with different ambiguities. Use a dedicated tool
  • You are working with a binary XML format — paste the text, the tool does not handle binary

Frequently asked questions

What happens to attributes?

By default, each attribute becomes a key prefixed with @ (for example, `<a href="x">` becomes `{ "@href": "x" }`). You can turn the prefix off in the options if your consumer expects attribute keys without the marker.

What happens to repeated elements?

If a parent has multiple children with the same tag, they become a JSON array. If a parent has only one child with that tag, it is left as a single object — so the shape changes when you add or remove duplicates.

Are comments preserved?

By default, no — XML comments are stripped. Toggle the 'Preserve comments' option to keep them under a #comment key inside their parent element.
