JSON to XML Converter — How It Works and When to Use It

Why Convert JSON to XML?

JSON has largely replaced XML for REST APIs, but XML is still widely used in enterprise systems, SOAP web services, RSS feeds, Microsoft Office file formats, and legacy integrations.

How the Conversion Works

JSONKit converts each JSON key into an XML element tag. Values become the text content of that element. Nested objects become nested elements. Arrays become repeated item elements.

json

{
  "user": {
    "name": "Ravi Mehta",
    "age": 28,
    "roles": ["admin", "editor"]
  }
}

Converts to:

xml

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <user>
    <name>Ravi Mehta</name>
    <age>28</age>
    <roles>
      <item>admin</item>
      <item>editor</item>
    </roles>
  </user>
</root>

Configurable Root Tag

Every XML document must have a single root element. JSONKit wraps all content in a configurable root tag. The default is root but you can change it in the input field in the page header. The output re-converts instantly when you change the tag.

Special Character Escaping

XML has five reserved characters that must be escaped: ampersand, less-than, greater-than, double quote, and single quote. JSONKit handles all escaping automatically.

Downloading the Output

Click Download XML in the output stats bar to save the result as an .xml file with the correct MIME type. This is ready to send to any XML-consuming system.

XML Tag Name Rules

If a JSON key contains spaces or special characters or starts with a number, JSONKit replaces invalid characters with underscores to produce a valid XML tag name automatically.
