JSON to XML Converter

About this tool

Convert JSON into XML in a single step. JSON is the default interchange format for web APIs; XML is the markup format behind SOAP, RSS, sitemaps and countless enterprise feeds. The converter is structure-aware rather than a text substitution, so nesting, types and ordering are preserved.

When you would use it

• Feeding JSON data to a service that only accepts XML
• Migrating a dataset from JSON to XML
• Inspecting JSON in a shape that is easier to read

Worked example

{
  "id": 4815,
  "name": "Ada Lovelace",
  "active": true,
  "score": 91.5,
  "roles": ["admin", "editor"],
  "address": { "city": "London", "postcode": "NW1" }
}

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <id>4815</id>
  <name>Ada Lovelace</name>
  <active>true</active>
  <score>91.5</score>
  <roles>admin</roles>
  <roles>editor</roles>
  <address>
    <city>London</city>
    <postcode>NW1</postcode>
  </address>
</root>

Things worth knowing

• Keys beginning with @ become attributes; everything else becomes an element.
• Arrays repeat the element rather than creating a wrapper, which is the convention most XML consumers expect.
• Keys that are not valid XML names are sanitised, since XML element names cannot contain spaces or start with a digit.
