XML to JSON Converter Online - Bidirectional
Convert between XML and JSON formats. Supports SOAP APIs, RSS feeds, SAML assertions, SVG graphics, and data exchange
About This XML to JSON Converter
Tool for XML to JSON conversion. This tool is part of the AI JSON Tools collection, providing specialized functionality for developers working with XML-based APIs, RSS feeds, and data interchange formats. All processing happens entirely in your browser—your data never leaves your device.
How It Works
This tool uses the xml-js 1.6.11 library to parse XML input and convert it to a compact JSON representation. XML attributes are stored under _attributes, text content under _text, and elements are nested as object properties. The conversion is bidirectional—you can also paste JSON and convert it back to XML.
Common Use Cases
Developers use this tool for: 1) Converting SOAP API responses to JSON for modern applications, 2) Parsing RSS/Atom feeds into structured JSON data, 3) Transforming SAML assertions for identity workflows, 4) Converting SVG markup to JSON for programmatic manipulation, 5) Migrating legacy XML-based systems to JSON APIs.
Technical Details
The converter is built with vanilla JavaScript and the xml-js 1.6.11 library loaded via CDN. It uses compact JSON representation (not verbose) for cleaner output. XML namespaces, processing instructions, and CDATA sections are all handled correctly.
Privacy & Security Guarantee
No data leaves your browser. All XML to JSON conversion happens locally using JavaScript. This means you can safely work with sensitive data including SOAP API credentials, SAML tokens, and proprietary XML documents. There is no server-side processing.
XML to JSON Conversion - How It Works
XML to JSON
Parse XML into compact JSON representation. Attributes use _attributes key, text content uses _text key.
JSON to XML
Convert JSON objects back to well-formed XML. Supports custom root element naming.
Namespace Support
Fully preserves XML namespaces (e.g., soap:Envelope, xsd:schema) during conversion.

How are XML attributes represented in JSON?
XML attributes are stored under the _attributes key as a JSON object. For example, <user type="admin">John</user> becomes: {"user": {"_attributes": {"type": "admin"}, "_text": "John"}}
Are XML namespaces preserved?
Yes. Namespace prefixes (e.g., soap:Envelope, xsd:schema) are preserved as key names in the JSON output. The colon is kept in the property name.
Can I convert large XML files?
The converter processes data in-memory using JavaScript. Most XML files under 10MB convert smoothly. For very large files, consider using a command-line tool like xml2js or xq.
Does it support XML with CDATA sections?
Yes. CDATA sections are properly parsed and their content is preserved in the JSON output. The text is stored as regular string content.
