XML (Extensible Markup Language) and JSON (JavaScript Object Notation) are two of the most widely used formats for data interchange. While XML has long been the backbone of enterprise APIs, configuration files, and legacy web services, modern applications overwhelmingly prefer JSON for its simplicity, lighter footprint, and native compatibility with JavaScript and REST APIs.
Whether you're migrating a legacy XML-based API to a modern JSON format, extracting data from an XML file to feed into a JavaScript application, or simply transforming a configuration file during a DevOps workflow, having a reliable XML to JSON converter in your toolkit is invaluable.
Our free online XML parser handles a wide range of XML structures — including nested elements, attributes, mixed content, and XML declarations — and outputs clean, indented JSON that you can immediately use in your projects. No installation, no registration, and no data ever leaves your device.
Powered by the browser's native DOMParser, your XML is parsed and converted to structured JSON in milliseconds — entirely client-side.
Your XML data never leaves your browser. Zero server uploads mean complete privacy — perfect for sensitive configuration files or proprietary data.
Results are pretty-printed with 2-space indentation, making them immediately readable, diffable, and ready to paste into any codebase or editor.
Nested elements, XML attributes, arrays of sibling nodes, and mixed text content are all gracefully handled in the data transformation process.
Export the converted output as a .json file with one click — ready to drop directly into your project or pipeline.
Invalid or malformed XML is caught immediately with clear error messaging, so you never silently corrupt your data during transformation.
Copy XML from your source — an API response, a configuration file, a data export, or any XML document — and paste it into the input panel. You can also click Load Sample to explore the converter with example data before using your own.
Hit the convert button (or press Ctrl+Enter). The tool parses your XML document, recursively maps elements and attributes to JSON keys and values, and formats the output with clean indentation for immediate readability.
Use the Copy JSON button to paste the result directly into your code editor, or click Download to save it as a .json file. Your converted data is production-ready the moment the transformation completes.
<name>Alice</name>), supports attributes, comments, and schemas, and is common in enterprise and legacy systems. JSON uses a more compact key-value syntax that maps directly to objects in most programming languages, making it the preferred format for modern REST APIs, web apps, and NoSQL databases. Converting XML to JSON is a common data transformation task when integrating legacy services with modern stacks.
@attributes key within the corresponding JSON object. For example, an element like <user id="42">Alice</user> will produce a JSON object with both an @attributes key containing the id and a #text key for the inner content. This is a widely adopted convention in XML-to-JSON data transformation that preserves all the original information without data loss.
.xml file in any text editor (Notepad, VS Code, Sublime Text), select all the content, and paste it into the converter. After conversion, you can download the result as a .json file using the Download button. We're continually improving the tool, and direct file upload support is on the roadmap.
<?xml version="1.0"?>). Very large documents, binary-encoded XML, or documents relying on advanced features like XInclude or external DTD entities may have limitations. For standard XML data transformation use cases — API responses, config files, data exports — the tool works reliably out of the box.
Join developers, data engineers, and architects who rely on fast, accurate XML parsing and conversion every day. No sign-up required — just scroll up and start converting.
