XML → JSON Converter

Free XML to JSON Converter — Instant Bidirectional Conversion

XML and JSON are the two dominant data interchange formats in web development and APIs. XML is the older standard — verbose, hierarchical, and still widely used in enterprise systems, configuration files, web services, and data feeds. JSON is the modern standard — compact, easy to parse, and the native format for JavaScript. Converting between them is a daily task for developers integrating legacy systems, consuming third-party data feeds, and migrating APIs. This free XML to JSON Converter converts in both directions instantly, all in your browser.

Paste XML to convert it to formatted JSON, or paste JSON to convert it back to XML. The converter handles nested structures, arrays, attributes, and complex schemas. The output is pretty-printed and ready to copy.

Common scenarios: RSS feed XML to JSON for a JavaScript application, SOAP XML response to JSON for easier parsing, configuration XML to JSON for a Node.js app, and API JSON response to XML for a legacy system integration.

XML vs JSON

XML syntax. Uses opening and closing tags: <name>John</name>. Supports attributes: <user id="1">. Supports comments, namespaces, and schemas (XSD). Verbose but highly structured.

JSON syntax. Uses key-value pairs: "name": "John". No attributes — all data is values or nested objects. No comments in standard JSON. Compact and fast to parse.

File size. JSON is typically 30–50% smaller than the equivalent XML for the same data, reducing bandwidth and parse time.

Browser/JavaScript support. JSON.parse() and JSON.stringify() are built into JavaScript. XML requires the DOMParser API or third-party library for equivalent functionality.
