How XML to JSON Conversion Works

XML is a hierarchical, tag-based format while JSON uses objects and arrays. This converter intelligently handles:

Element values become string or object properties depending on content
Nested elements become nested objects automatically
Multiple same-name siblings are grouped into arrays
Attributes are preserved and prefixed with @ (configurable)
Text content mixed with child elements is preserved in a _text property
CDATA sections are parsed as regular text content

Common Use Cases

XML to JSON conversion is essential for:

API migrations — Converting legacy XML APIs to modern JSON-based APIs
Data transformation — Preparing XML data from external sources for JavaScript/web applications
Configuration management — Converting XML config files to JSON for easier parsing
Data interchange — Bridging systems that use different data formats
Web services — Consuming SOAP XML responses in REST JSON applications

XML vs JSON Comparison

Aspect	XML	JSON
Syntax	Tag-based with opening/closing tags	Object and array notation
File size	Larger due to closing tags	More compact and concise
Readability	Verbose but self-documenting	Clean and lightweight
Attributes	Native support for attributes	Attributes become object properties
Arrays	Implicit (repeated tags)	Explicit with [ ] notation
Data types	All values are strings by default	Supports numbers, booleans, null
Web APIs	Legacy systems (SOAP)	Modern APIs (REST, GraphQL)

Conversion Tips & Examples

Simple element conversion

XML:

<person>
  <name>John</name>
  <age>30</age>
</person>

JSON:

{
  "person": {
    "name": "John",
    "age": "30"
  }
}

Array handling (repeated elements)

XML:

<users>
  <user>Alice</user>
  <user>Bob</user>
</users>

JSON:

{
  "users": {
    "user": ["Alice", "Bob"]
  }
}

Attributes with content

XML (with attributes):

<book isbn="978-0-201-61622-4">
  Design Patterns
</book>

JSON (with @ prefix):

{
  "book": {
    "@isbn": "978-0-201-61622-4",
    "_text": "Design Patterns"
  }
}

Handling namespaces

XML namespaces (prefixes like soap:) are preserved as-is in element names. You can manually clean them in the JSON output if needed.

Large files

This converter works entirely in your browser and can handle large XML files (megabytes), but very large files may take a few seconds to process. Complex nested structures will result in larger JSON files.
