XML → JSON Converter
Introduction
XML and JSON are two of the most widely used formats for exchanging and storing structured data. XML (eXtensible Markup Language) is verbose and favoured where document structure and validation are important, while JSON (JavaScript Object Notation) is compact and easy to work with in modern web applications and APIs. Converting XML to JSON is a common task for developers, data engineers, and content managers — especially when integrating legacy systems with modern JavaScript-based stacks. This free XML to JSON converter page provides a simple, client-side tool to convert, validate, beautify and download the resulting JSON with zero tracking and no server uploads.
Description & Features
The tool supports pasting raw XML, uploading an .xml file, or drag-and-drop. It includes features such as validation (basic well-formed checks), conversion that preserves attributes and text nodes, beautify and minify options for JSON output, copy-to-clipboard and one-click JSON download. Everything runs in the browser — perfect for quick conversions, learning, and embedding into documentation or a Blogger post.
How it works
Under the hood the converter uses the browser's DOMParser to parse XML into a DOM tree, then traverses that tree to build an equivalent JSON object. We use a simple but robust mapping: XML attributes become an "@attributes" object inside the node; text content is stored with a special "#text" key when mixed content exists; child nodes are converted into arrays when multiple siblings share the same tag name. This mapping keeps the structure predictable and reversible in many cases.
When to use XML → JSON conversion
Use this converter when you need to integrate XML feeds into JavaScript applications, migrate legacy XML configuration to JSON files, or quickly inspect XML content in a more concise JSON form. It's handy for developers working with RSS/Atom feeds, SOAP responses, and older enterprise systems that still export XML.
Performance & Privacy
Because the conversion happens entirely in the browser (no external servers involved), the performance depends only on your device and the size of the XML. For very large XML files (>~10MB), conversion may take a moment and your browser could become temporarily slow. For those, consider server-side streaming approaches. Privacy-conscious users will appreciate that no content is uploaded or logged — everything stays local.
SEO & Blogger optimization
This HTML file is structured to be Blogger-friendly: it includes meta description, keywords, canonical URL, and Schema.org Article structured data. The article content below the tool is written for search relevance, answering common user queries like "how to convert XML to JSON" and "online XML to JSON converter". If you paste this file into a Blogger post's HTML view, the interactive tool will work for visitors (note: Blogger may strip some inline scripts depending on settings — you can host the script externally or embed via an iframe if needed).
Frequently Asked Questions (FAQ)
Q: Is my data uploaded to a server?
A: No. All processing happens in your browser. The tool is client-side only.
Q: How do attributes and text nodes map to JSON?
A: Attributes become an "@attributes" object. If a node has both text and children, the text is stored under "#text" to avoid conflicts.
Q: Can I convert large files?
A: Up to a few megabytes works fine client-side. For very large XML files, prefer server-side or streaming converters.
Q: Can I reverse the conversion (JSON → XML)?
A: Not directly from this tool, but the mapping used aims to be reversible. Implementing JSON→XML needs a compatible mapping and is possible with additional code.
