Our free, open-source, and ad-free XML to JSON converter makes it easy to transform your data formats. Convert configuration files, API responses, or legacy XML data into modern JSON with just a few clicks.

Why Convert XML to JSON?

XML (eXtensible Markup Language) has been a standard for data exchange for decades, but JSON (JavaScript Object Notation) has become the preferred format for modern web development. Converting XML to JSON is essential when you need:

Most modern REST APIs use JSON, making conversion essential for integrating legacy XML data.

JSON is more compact than XML, reducing bandwidth and improving performance.

JSON is native to JavaScript, making it easier to work with in web applications.

JSON's simpler syntax makes data easier to read and understand compared to verbose XML.

Key Features of Our XML to JSON Tool

Your data never leaves your browser - complete privacy guaranteed.

XML attributes are preserved using the @attributes convention, compatible with popular libraries like xml2js.

Multiple elements with the same name are automatically converted to arrays.

Mixed content with text and attributes uses the #text key for clarity.

Invalid XML is detected and reported immediately with helpful error messages.

Follows industry-standard conversion patterns used by major XML parsing libraries.

XML vs JSON: When to Use Each

Both XML and JSON have their strengths. Here's when to use each:

Documents with mixed content, complex schemas requiring validation, XSLT transformations, SOAP web services, and when namespaces are needed.

REST APIs, configuration files, web applications, mobile apps, NoSQL databases, and when file size and parsing speed matter.

Understanding the Conversion Format

Our converter uses industry-standard conventions:

XML attributes are grouped in an @attributes object, matching the behavior of popular libraries like xml2js.

When an element has both text content and attributes or child elements, the text is stored under a #text key.

Multiple sibling elements with the same name are automatically converted to JSON arrays.

Self-closing or empty XML elements are converted to null in JSON.

FAQs

XML (eXtensible Markup Language) is a markup language that defines rules for encoding documents in a format that is both human-readable and machine-readable. It's widely used for data exchange and configuration files.

JSON (JavaScript Object Notation) is a lightweight data format used to transmit data between servers and web applications. It's the standard format for modern REST APIs.

XML attributes are converted to an @attributes object in the JSON output, preserving all attribute data while maintaining compatibility with standard XML parsing libraries.

Yes! Since processing happens in your browser, you can convert files of any size. However, very large files may take longer to process depending on your device's capabilities.

Absolutely! All processing happens entirely in your browser. Your XML data is never sent to any server, ensuring complete privacy and security.

While our tool focuses on XML to JSON conversion, you can manually restructure JSON back to XML format. Note that some information like attribute order may not be perfectly preserved.

XML namespaces are preserved in the element names. For example, ns:element becomes "ns:element" in the JSON output.
