About XML ↔ JSON Converter

Fast, bidirectional conversion between XML and JSON formats entirely in your browser. Convert XML documents to structured JSON objects, or transform JSON data back into well-formed XML. Essential for API integration, data transformation, and working with systems that use different data formats.

How to use this tool:

  1. Select the conversion direction using the toggle button (XML → JSON or JSON → XML).
  2. Paste your input data in the left panel.
  3. Click "Convert" to transform the data.
  4. Copy the output from the right panel.

Frequently Asked Questions

How are XML attributes handled?

XML attributes are preserved with an "@_" prefix in the JSON output (e.g., @_id, @_class). This prefix is converted back to attributes when converting JSON to XML.

Can I convert large XML files?

Yes. The parser handles large files efficiently in your browser. Very large files (>10 MB) may take a few seconds.

Does this preserve XML namespaces?

Basic namespace declarations are preserved. Complex namespace handling may require specialized XML tools for full fidelity.

🔒 Are my files uploaded to a server?

No. MyConverterPro processes all files locally inside your browser using client-side JavaScript. Your data never leaves your device, ensuring 100% privacy and security.

✓Key Takeaways

  • Bidirectional conversion: XML → JSON and JSON → XML in a single tool
  • Proper handling of XML attributes (prefixed with @_ in JSON output)
  • Supports complex nested structures, namespaces, and CDATA sections
  • Powered by fast-xml-parser for high-performance, enterprise-grade parsing

XML and JSON are the two dominant data interchange formats in software development, and they represent fundamentally different philosophies. XML (eXtensible Markup Language) uses a verbose, tag-based syntax with support for attributes, namespaces, schemas, and validation. JSON (JavaScript Object Notation) uses a lightweight, minimalist syntax that maps directly to programming language data structures. Enterprise systems, SOAP APIs, and legacy applications tend to use XML. Modern REST APIs, web applications, and mobile backends overwhelmingly prefer JSON.

The need to convert between these formats arises constantly in real-world development. You might receive data from a legacy SOAP API in XML format that needs to be processed by your modern JavaScript application. Or you might have JSON data from your API that needs to be submitted to a government or financial system that only accepts XML. Configuration files, data exports, and integration middleware frequently require translation between these formats.

Our XML ↔ JSON converter handles both directions instantly. Powered by the fast-xml-parser library — one of the most performant and accurate XML parsers in the JavaScript ecosystem — the tool correctly handles complex XML features including attributes, namespaces, CDATA sections, comments, and deeply nested element hierarchies. The conversion preserves all data relationships and produces clean, well-formatted output in both directions.

The bidirectional design means you can toggle between XML-to-JSON and JSON-to-XML modes within the same interface. Paste XML and get formatted JSON. Paste JSON and get valid XML. The tool handles edge cases that simpler converters miss — mixed content (text and child elements), self-closing tags, numeric and boolean value detection, and proper XML attribute mapping.
