What Is a JSON to XML Converter?

JSON (JavaScript Object Notation) stores data as key/value pairs and arrays. XML (Extensible Markup Language) stores data inside nested tags with attributes. Modern apps and REST APIs speak JSON, but many enterprise systems, SOAP services, RSS feeds, sitemaps and configuration files still require XML.

A JSON to XML converter bridges the two: objects become elements, arrays become repeated elements, and values become text nodes, so you can feed JSON data into any XML-based system without writing the markup by hand.

How to Convert JSON to XML Online

1. Paste your JSON into the input box, or upload a .json file.
2. Click “Convert”. The tool validates your JSON first and points to the exact line of any syntax error.
3. Copy or download the formatted XML.
4. Need JSON again? Press “Swap” to use the XML to JSON converter.

Quick example

{
  "order": {
    "@id": "101",
    "customer": "Anna",
    "item": ["Shirt", "Cap"]
  }
}

<order id="101">
  <customer>Anna</customer>
  <item>Shirt</item>
  <item>Cap</item>
</order>

How JSON Maps to XML

Key Features

• Fast and free: instant conversion, no limits, no account.
• Valid output: special characters are escaped (&, <, >) so the XML is well-formed.
• Arrays handled: every array item becomes its own element.
• Attribute support: use the @ prefix to create XML attributes.
• Custom root element: choose the root tag name and the XML declaration.
• Pretty print or minify: readable output, or compact output for production.
• Two-way: JSON to XML and XML to JSON in one tool.
• Private: conversion happens in your browser.

Why Convert JSON to XML?

• Legacy and enterprise systems: many ERPs, banking and government services only accept XML.
• SOAP web services: SOAP requests are XML envelopes.
• Feeds and sitemaps: RSS, Atom and XML sitemaps are XML by definition.
• Validation: XML supports XSD schemas and XSLT transforms for strict data contracts.
• Configuration files: Android, Maven, .NET and many tools use XML configs.

JSON vs XML: Quick Comparison

Convert JSON to XML in Code

JavaScript (Node.js)

import { XMLBuilder } from "fast-xml-parser";
const builder = new XMLBuilder({ format: true, attributeNamePrefix: "@", ignoreAttributes: false });
const xml = builder.build(JSON.parse(jsonString));

Python

import json, xmltodict
xml = xmltodict.unparse(json.loads(json_string), pretty=True)

PHP

$data = json_decode($json, true);
$xml = new SimpleXMLElement('<root/>');
array_walk_recursive($data, function ($v, $k) use ($xml) { $xml->addChild($k, $v); });
echo $xml->asXML();

For nested data and attributes the online tool above is quicker, and you can check the result with our XML Beautifier.

Tips for Accurate JSON to XML Conversion

• Make sure your JSON is valid: double quotes, no trailing commas, matching brackets.
• XML needs a single root element. If your JSON has several top-level keys, the tool wraps them in a root you can rename.
• XML element names cannot start with a number or contain spaces. Rename such keys first.
• Use @ keys for attributes to keep your XML compact.
• JSON numbers and booleans become plain text in XML, so define types in an XSD if the receiver needs them.
