XML to JSON Converter (Free AI Tool)
Convert XML to JSON with intelligent attribute and namespace handling. Transform SOAP API responses, RSS feeds, and SVG files to JSON format. Client-side processing ensures your XML data stays secure.
Paste code in both editors to see differences
Hint: Paste original code on left, modified code on right, then click Compare to see differences highlighted.

Hint: Paste your JWT token to decode and view its header, payload, and signature. The tool validates token structure and format.
Hint: Select conversion type, paste your data, and get instant conversion. Supports JSON, YAML, XML, Excel, PDF, and more.
How It Works
- 1
Paste XML Document with Namespaces
Paste your XML data including SOAP responses, RSS feeds, configuration files, or any XML with attributes and namespaces like xmlns:prefix declarations.
- 2
AI Parses Elements and Attributes
The converter analyzes XML structure, converting elements to JSON objects and attributes to properties. Repeated elements become JSON arrays. Namespaces are preserved with prefix notation.
- 3
Copy JSON for REST APIs
Receive structured JSON output ready for JavaScript, Python, or Node.js consumption. Use in REST API payloads, front-end applications, or data processing pipelines.
XML vs JSON: Format Comparison
| Feature | XML | JSON |
|---|---|---|
| Syntax | Tag-based markup | Key-value pairs |
| Attributes | Element attributes | Nested objects or @ prefix |
| Arrays | Repeated elements | JSON arrays [] |
| Namespaces | xmlns:prefix | Colon-prefixed keys |
| Use Case | SOAP, RSS, config files | REST APIs, JavaScript |
| Readability | Verbose | Compact |
Code Examples
Example 1: Simple XML with Attributes
<?xml version="1.0"?>
<user id="101" active="true">
<name>John Smith</name>
<email>[email protected]</email>
<role>admin</role>
</user>{
"user": {
"@id": "101",
"@active": "true",
"name": "John Smith",
"email": "[email protected]",
"role": "admin"
}
}Key Changes:
XML attributes (id, active) are converted to JSON properties with @ prefix to distinguish them from nested elements. The root element becomes a JSON object key. Child elements (name, email, role) become nested properties. This format allows JavaScript code to access attributes via user['@id'] and elements via user.name, maintaining semantic distinction between XML attributes and elements.
Example 2: RSS Feed with Repeated Elements
<?xml version="1.0"?>
<rss version="2.0">
<channel>
<title>Tech Blog</title>
<item>
<title>Post 1</title>
<link>https://example.com/1</link>
</item>
<item>
<title>Post 2</title>
<link>https://example.com/2</link>
</item>
</channel>
</rss>{
"rss": {
"@version": "2.0",
"channel": {
"title": "Tech Blog",
"item": [
{
"title": "Post 1",
"link": "https://example.com/1"
},
{
"title": "Post 2",
"link": "https://example.com/2"
}
]
}
}
}Key Changes:
Repeated XML elements (multiple <item> tags) are automatically detected and converted to JSON arrays. The RSS version attribute becomes @version property. This transformation is critical for RSS/Atom feed parsing where multiple posts must be iterable. JavaScript code can now loop through rss.channel.item array using forEach() or map(), enabling easy feed consumption in web applications. The hierarchical structure is preserved while gaining JSON's array benefits.
Frequently Asked Questions
XML attributes are converted to JSON properties with an @ prefix or as nested objects depending on conversion strategy. For example, <user id='123' name='John'/> becomes either {'@id': '123', '@name': 'John'} or {'user': {'id': '123', 'name': 'John'}}. The converter intelligently chooses the most appropriate format based on XML structure.
Yes. The converter processes XML namespaces and prefixes, converting them to JSON keys. Namespaces like <ns:element> are preserved as 'ns:element' in JSON keys. For complex namespace-heavy XML (SOAP, SVG), review output to ensure proper data access patterns.
Yes. Mixed content is converted with text nodes as special properties. For example, <p>Hello <b>world</b></p> converts to nested JSON preserving both text and child elements. This handles HTML-like XML and documentation formats accurately.
