JSON to XML Conversion: When and How to Use It
2026-04-22 6 min read
XML (eXtensible Markup Language) predates JSON by decades. Enterprise systems, SOAP APIs, and healthcare/financial integrations still rely on XML heavily. Our JSON to XML converter bridges this gap, letting you work with modern JSON internally and export to XML for legacy systems.
JSON to XML Mapping
| JSON | XML |
|---|---|
| {...} | |
| Key-value pairs | Elements with text content |
| Arrays | Repeated elements or wrapped collection |
| Null | Empty element or omitted |
Conversion Example
JSON input
{
"person": {
"name": "Alice",
"age": 30,
"email": "alice@example.com"
}
} XML output
<?xml version="1.0" encoding="UTF-8"?>
<root>
<person>
<name>Alice</name>
<age>30</age>
<email>alice@example.com</email>
</person>
</root>When to Use XML
- SOAP web services and legacy enterprise APIs
- Healthcare systems (HL7 messaging)
- Financial institutions (ISO 20022)
- XML-based configuration (Maven, Gradle, Android)
- Office documents (Word, Excel, PowerPoint are zipped XML)
Pro tip
Most modern systems prefer JSON-based APIs. Use XML conversion sparingly — only when integrating with systems that require it. JSON is easier to parse, consume less bandwidth, and is more intuitive for developers.
