What is XML to JSON Converter?
Our XML to JSON Converter transforms XML structured data into JSON format with one click. Whether you're integrating legacy systems, working with SOAP APIs, or migrating data to modern REST APIs, our tool makes XML to JSON conversion effortless.
XML and JSON are both data interchange formats, but JSON is lighter, easier to parse in JavaScript, and more widely used in modern web development. Converting XML to JSON lets you work with legacy XML data in modern applications, integrate old SOAP services with new REST APIs, and simplify data processing in JavaScript.
The tool handles complex XML structures including nested elements, attributes, arrays, and CDATA sections. It automatically detects XML structure and converts it to proper JSON with arrays for repeated elements. You can also validate XML syntax before conversion and format the output JSON for readability.
All conversions happen locally in your browser - no servers, no uploads, completely private. Works offline once loaded, perfect for processing sensitive configuration files, customer data, or proprietary XML schemas in secure environments.

Frequently Asked Questions
Everything you need to know about XML to JSON Converter
XML attributes are converted to JSON properties with an @ prefix by default. For example, <book id="123"> becomes {"book": {"@id": "123"}}. This preserves the distinction between element content and attributes in the JSON output.
Currently this tool only converts XML to JSON. JSON to XML conversion is more complex because JSON lacks XML features like attributes and namespaces, requiring manual decisions about structure mapping. Use a dedicated JSON to XML tool for reverse conversion.
Repeated elements are automatically converted to JSON arrays. If <items><item>A</item><item>B</item></items>, the output is {"items": {"item": ["A", "B"]}}. Single elements stay as objects, multiple become arrays.
Yes, XML namespaces are preserved in the JSON keys. For example, <ns:element xmlns:ns="http://example.com"> becomes {"ns:element": {...}}. The namespace prefix is included in property names.
The tool can handle very large XML files (10MB+) since processing happens in your browser. However, browser memory limits apply - if you experience slowdowns with huge files, try splitting them into smaller chunks.
No! All conversion happens entirely in your browser using JavaScript. Your XML data is never uploaded to any server, making it completely safe for sensitive config files, customer data, or proprietary schemas.
