JSON to XML Converter: Integration Guide (APIs, Legacy Systems)

XML is still a real requirement in many environments:

• Enterprise integrations
• Legacy systems
• SOAP-style workflows
• Vendor import/export formats

If your data is in JSON but your destination expects XML, use our JSON to XML converter to generate clean XML instantly.

Quick example: JSON → XML

JSON input

json{
  "order": {
    "id": "ORD-2026-0001",
    "customer": { "name": "Alice" },
    "items": [
      { "sku": "SKU-001", "qty": 1 },
      { "sku": "SKU-002", "qty": 2 }
    ]
  }
}

XML output

xml<?xml version="1.0" encoding="UTF-8"?>
<root>
  <order>
    <id>ORD-2026-0001</id>
    <customer>
      <name>Alice</name>
    </customer>
    <items>
      <sku>SKU-001</sku>
      <qty>1</qty>
    </items>
    <items>
      <sku>SKU-002</sku>
      <qty>2</qty>
    </items>
  </order>
</root>

Step-by-step: how to convert JSON to XML

1. Open JSON to XML
2. Paste JSON on the left (or click Sample)
3. Copy or download XML from the right panel

How JSON maps to XML (what to expect)

Objects become nested elements

A JSON object becomes a nested XML structure.

Arrays become repeated elements

JSON arrays typically become repeated XML nodes (multiple in the example above).

This is the most common and compatible representation for many import formats.

When you should prefer XML

Use XML when:

• A vendor requires XML uploads
• Your pipeline is already XML-based (XSLT, XML Schema, SOAP)
• You need attributes/namespaces (advanced XML workflows)

If you’re building new systems, JSON is often simpler—but conversions are still part of real-world integration work.

Convert back when needed

If you receive XML from a partner system, use XML to JSON.

The conversion runs in your browser. Your data is not uploaded.
