JSON to XML Converter (Free Online Tool)
Convert JSON to XML instantly for SOAP APIs and legacy system integration. Generate valid, well-formed XML documents with proper nesting, array handling, and encoding. Transform modern REST API responses to XML for enterprise systems. All processing happens client-side.

Hint: Paste original code on left, modified code on right, then click Compare to see differences highlighted.
Hint: Paste your code, customize font size and line numbers, then click Export PDF to download formatted code.
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 JSON Data or API Response
Input your JSON from REST APIs, configuration files, or database exports. The converter handles nested objects, arrays, and primitive values.
- 2
AI Transforms to XML Structure
The AI converts JSON objects to XML elements, arrays to repeated tags with singularized names, and primitive values to text nodes. Special characters are properly encoded with XML entities or CDATA sections.

Copy Valid XML with Proper Encoding
Receive well-formed XML with XML declaration, proper nesting, escaped special characters, and namespace support if needed. Ready for SOAP web services or legacy XML-based systems.
JSON vs XML: Format Comparison
| Feature | JSON | XML |
|---|---|---|
| Syntax | Key-value pairs with colons | Tagged elements with nesting |
| Arrays | Native array syntax [] | Repeated elements |
| Data Types | Number, String, Boolean, null | All text (with type hints) |
| Attributes | No native concept | Element attributes @attr |
| Comments | Not allowed in standard JSON | XML comments <!-- --> |
| Whitespace | Insignificant | Can be significant |
Code Examples
Example 1: Simple Object to XML
{
"user": {
"id": 123,
"name": "John Doe",
"email": "[email protected]",
"active": true
}
}<?xml version="1.0" encoding="UTF-8"?>
<root>
<user>
<id>123</id>
<name>John Doe</name>
<email>[email protected]</email>
<active>true</active>
</user>
</root>Key Changes:
JSON objects convert to nested XML elements. Each JSON key becomes an XML tag, and JSON values become text content. Boolean and number values are converted to strings in XML since XML doesn't have native data types. The root element wraps the entire structure. JSON's clean syntax expands into XML's more verbose tag-based format.
Example 2: Arrays to Repeated Elements
{
"users": [
{"id": 1, "name": "Alice"},
{"id": 2, "name": "Bob"},
{"id": 3, "name": "Charlie"}
],
"count": 3
}<?xml version="1.0" encoding="UTF-8"?>
<root>
<users>
<user>
<id>1</id>
<name>Alice</name>
</user>
<user>
<id>2</id>
<name>Bob</name>
</user>
<user>
<id>3</id>
<name>Charlie</name>
</user>
</users>
<count>3</count>
</root>Key Changes:
JSON arrays convert to repeated XML elements. The array name (users) becomes a container element, and each array item becomes a repeated child element (user, singularized). This pattern matches common XML conventions for collections. Primitive values outside arrays remain as single elements. The XML structure explicitly shows each list item as a separate element, making the hierarchical relationship clear.
Frequently Asked Questions
JSON arrays convert to repeated XML elements with the same tag name. For example, {"users": [{"name": "Alice"}, {"name": "Bob"}]} becomes <users><user><name>Alice</name></user><user><name>Bob</name></user></users>. The converter automatically singularizes array item tags. Arrays of primitives wrap each value in an <item> element by default.
No. All JSON to XML conversion happens entirely in your browser using client-side JavaScript. Your JSON data—whether API responses, configuration files, or database exports—never leaves your machine. The tool works offline once loaded.
The converter follows common XML conventions by default, creating elements for JSON properties and values. JSON keys starting with @ are converted to XML attributes (e.g., {"@id": "123", "name": "Item"} becomes <item id="123"><name>Item</name></item>). The default output prioritizes readability and standard XML structure.
