JSON to XML Converter

How to Convert JSON to XML

1. Paste your JSON into the input field on the left. The JSON can be an object or an array.
2. Click Convert to XML. The XML output appears in the right panel.
3. Click Copy to copy the XML to your clipboard.
4. Optionally download the result as an .xml file.

The converter handles nested objects, arrays, strings, numbers, booleans, and null values. Arrays are converted to repeated XML elements. Nested objects become nested elements.

How JSON Values Map to XML

JSON keys become XML element names. Keys that start with a number or contain spaces are sanitized (spaces become underscores, numeric prefixes get an underscore prepended) to produce valid XML element names.

Why Convert JSON to XML?

• Legacy system integration — many enterprise APIs, banking systems, and ERP platforms require XML or SOAP. Converting JSON payloads enables integration without changing the source system.
• XSLT transformations — XML supports XSLT stylesheets for powerful document transformation. Converting JSON to XML allows you to apply these transforms.
• Document generation — XML underlies DOCX, XLSX, PPTX, and SVG. Some document generation workflows require XML input.
• RSS/Atom feeds — publishing platforms that generate feeds from JSON APIs need conversion to the XML-based RSS/Atom format.
• Configuration files — tools like Maven, Spring, and Ant use XML configuration. Converting from JSON templates simplifies toolchain integration.
• XML-based messaging — protocols like XMPP, e-invoicing standards (UBL, EDIFACT), and healthcare standards (HL7) use XML.

To go the other direction, use the XML to JSON converter.

JSON to XML: Quick Example

Input JSON:

{
  "person": {
    "name": "Alice",
    "age": 30,
    "roles": ["admin", "editor"]
  }
}

Output XML:

<?xml version="1.0" encoding="UTF-8"?>
<person>
  <name>Alice</name>
  <age>30</age>
  <roles>admin</roles>
  <roles>editor</roles>
</person>

Array elements become repeated elements with the same tag name (the key of the array). This is the standard XML pattern for lists.

JSON and XML Workflow Tools

JSON to XML conversion fits into an API integration or legacy system workflow:

• Validate the JSON first to catch syntax errors before converting
• Convert XML back to JSON — the reverse converter
• Format the source JSON for review before converting
• Export JSON to CSV as an alternative tabular format
• Format the XML output using our HTML formatter which handles XML indentation
