Introducción a la herramienta

Generate well-formed XML from JSON with a configurable root element, optional XML declaration, and pretty indentation. Useful for SOAP payloads, RSS drafts, and legacy systems.

Visión general de la herramienta

Each JSON key becomes an element; strings, numbers, and booleans become text content (XML-escaped). Arrays expand into repeated sibling elements with the same name. The top-level element defaults to `<root>`, but if your JSON has a single top-level key whose value is an object, that key is used as the root element instead — so the output stays natural.

Casos de uso

Build a SOAP request body from a JSON fixture
Draft an RSS/Atom feed item from structured data
Feed legacy enterprise systems that require XML
Produce XML sitemaps from a JSON content list

Ejemplos de entrada/salida

Intención de entrada

{"book":{"title":"Dune","author":"Frank Herbert","year":1965}}

Intención de salida

<?xml version="1.0" encoding="UTF-8"?>
<book>
  <title>Dune</title>
  <author>Frank Herbert</author>
  <year>1965</year>
</book>

Arrays expand into repeated sibling elements.

Intención de entrada

{"library":{"book":[{"title":"Dune"},{"title":"Foundation"}]}}

Intención de salida

<?xml version="1.0" encoding="UTF-8"?>
<library>
  <book>
    <title>Dune</title>
  </book>
  <book>
    <title>Foundation</title>
  </book>
</library>

null values become self-closing tags; numbers and strings become text content.

Intención de entrada

{"response":{"status":"ok","items":[1,2,3],"empty":null}}

Intención de salida

<response>
  <status>ok</status>

  <items>3</items>
  <empty/>

Preguntas frecuentes

Is this JSON to XML converter free?+

Yes. All processing is client-side, with no sign-up or file-size cap.

How are arrays represented?+

As repeated sibling elements sharing the parent key name. For example, {"tag":["a","b"]} becomes <tag>a</tag><tag>b</tag>.

How are special characters escaped?+

The five XML entities are escaped: <, >, &, ", and '. Numeric references like © are preserved as-is.

Can I skip the XML declaration?+

Yes. Toggle "Include <?xml declaration?>" off before converting if you need a pure XML fragment (for embedding inside another document).

Can I generate XML for SOAP, RSS, or sitemaps?+

Yes. Set the root element to Envelope, rss, or urlset to match your target schema. The converter emits well-formed XML ready to feed into an XSD or SOAP tool.
