JSON to XML Conversion Tips

Best practices for converting JSON to well-formed XML.

1

Understand the Data Model Differences

JSON uses key-value pairs and arrays; XML uses nested elements and attributes. Arrays become repeated elements, and leaf values become text content. Knowing this helps you predict the output structure.

2

Use Simple Key Names

JSON keys become XML element names. Avoid keys with spaces or special characters that are invalid in XML element names. Stick to alphanumeric keys with underscores.

3

Common Use Case: API to Legacy System Integration

Many legacy systems and SOAP services require XML. Converting a JSON API response to XML is a quick way to bridge modern REST APIs with older systems that expect XML input.

Conversion Features

Reliable JSON to XML conversion in your browser.

Well-Formed XML

Generates properly indented, well-formed XML with correct element nesting and escaping.

Array Handling

What is JSON to XML Conversion?

JSON to XML conversion transforms a JSON object into an XML document. Object keys become element tags, values become text content, and arrays generate repeated elements.

Input JSON

{ "name": "Alice", "age": 30 }

Output XML

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <name>Alice</name>
  <age>30</age>
</root>

JSON to XML FAQ

How are JSON arrays converted?

Array items are wrapped in a parent element matching the key name, with each item as a child 'item' element.

Are null values handled?

Yes, JSON null values are converted to empty XML elements.

Is the XML valid?

Yes, the output is well-formed XML with proper escaping. It includes an XML declaration and a root element.

Does it add an XML declaration header?

Yes, the output begins with an XML declaration followed by a root element containing the converted data.

How are booleans and numbers represented in XML?

JSON booleans and numbers are converted to their string representation as text content within XML elements. For example, true becomes an element containing the text 'true', and 42 becomes an element with '42' as its content.

Can I customize the XML element names?

Element names are derived directly from JSON keys. To control the naming, rename your JSON keys before converting. Keys with spaces or special characters will be sanitized for XML compatibility.

Is the output suitable for SOAP or web service integration?

The converter produces well-formed XML which is a good starting point. For SOAP services, you may need to add XML namespaces, envelope wrappers, and schema references specific to your service.
