What is JSON to XML conversion?

JSON to XML conversion transforms JavaScript Object Notation data into eXtensible Markup Language format, making it compatible with systems that require XML.

Is this converter free?

Yes! Our JSON to XML converter is 100% free with no limits on usage or file size.

All conversion happens in your browser. Your data never leaves your device or gets uploaded to any server.

Can I customize the XML output?

Yes, you can customize the root element name and formatting options for the generated XML.

JSON to XML Conversion Guide

1. Paste your JSON

Paste a valid JSON object or array into the input. The converter handles nested objects, arrays, and all JSON primitive types (strings, numbers, booleans, null).

2. Set options

Choose the root element name and whether to pretty-print the output. XML requires a single root element, so the converter wraps your data in the root tag you specify.

3. Copy the XML

Copy the generated XML to use in legacy systems, SOAP APIs, enterprise integrations, or any application that consumes XML but not JSON natively.

JSON vs XML: Side-by-Side Comparison

JSON

{
  "user": {
    "id": 42,
    "name": "Alice",
    "active": true,
    "tags": ["admin", "editor"]
  }
}

XML

<root>
  <user>
    <id>42</id>
    <name>Alice</name>
    <active>true</active>
    <tags>admin</tags>
    <tags>editor</tags>
  </user>
</root>

When to Use XML vs JSON

JSON has become the dominant data interchange format for web APIs due to its compact syntax, native browser support, and direct mapping to JavaScript objects. However, XML remains widely used in enterprise systems, SOAP web services, RSS and Atom feeds, Microsoft Office formats (DOCX, XLSX are ZIP files containing XML), Android resource files, and SVG graphics. Many legacy enterprise APIs (banking, healthcare HL7, government) require XML. If you are integrating with an older system or a SOAP endpoint, converting your JSON payload to XML is a common requirement. Conversion is always a one-way transformation — XML generated from JSON may not round-trip perfectly back to the original JSON structure due to differences in how each format handles arrays and attributes.
