XML to JSON Converter

Transform XML into JSON for Modern API Integrations

XML dominated web services and data interchange for decades before JSON emerged as the preferred format for REST APIs and JavaScript applications. Legacy enterprise systems, SOAP services, third-party data feeds, and older web services still speak XML fluently—but your frontend application, your Node.js service, and your mobile app all want JSON. The gap between these two worlds is where our free XML to JSON converter operates. Paste your XML, click convert, and receive a JSON representation of the same data that you can immediately use in JavaScript, pass to a JSON API, store in a document database, or feed into any JSON-consuming application.

The conversion runs entirely in your browser in under a second, regardless of the size or complexity of the XML document. No file upload, no server round trip, and no data leaving your device—everything processes locally using your browser's own JavaScript XML parsing capabilities.

How XML Maps to JSON

The structural translation between XML and JSON involves several mapping decisions because the two formats have fundamentally different data models. Understanding these mappings helps you interpret the converted output and adapt it for your specific use case.

XML elements map to JSON objects when they contain child elements, and to JSON string values when they contain only text content. A simple element like `Alice` becomes `"name": "Alice"` in JSON. A parent element with children becomes a JSON object with nested keys. The root element of the XML document typically becomes the top-level key in the JSON output.

XML attributes have no direct JSON equivalent. The standard convention is to represent them as keys within the corresponding JSON object, typically prefixed with `@` to visually distinguish them from element names. An XML element like `` might produce `{"@id": "42", "@role": "admin"}` in the JSON object for that element.

Repeated elements with the same name—which represent arrays in XML—become JSON arrays when the converter detects the repetition. A feed with multiple `` elements inside a `` element produces a `"item"` key with a JSON array value containing all the items as objects.

Common Use Cases for XML-to-JSON Conversion

Consuming SOAP APIs in Modern Applications

Many enterprise systems expose their functionality through SOAP web services that return XML responses. When building modern web or mobile applications that need to consume these services, converting the XML response to JSON allows you to work with the data using standard JavaScript JSON parsing rather than XML DOM manipulation, which is substantially more complex and less idiomatic in modern frontend and Node.js code. Convert the SOAP response to JSON and work with the data the way you'd work with any REST API response.

Processing RSS and Atom Feeds

News aggregators, podcast platforms, and content syndication systems consume RSS and Atom feeds, which are XML-based. Processing these feeds in a JavaScript backend typically involves either using an XML parser or converting the feed to JSON first. JSON-based processing is simpler to reason about and integrates more naturally with JavaScript toolchains. Converting RSS/Atom XML to JSON gives you the feed content in a format that maps directly to JavaScript objects.

Legacy System Data Migration

Migrating data from older systems that export XML to modern systems that expect JSON is a common integration challenge. Configuration exports, CRM data dumps, ERP record exports, and legacy database exports frequently come in XML format. Converting them to JSON is a prerequisite for importing them into modern APIs, document databases like MongoDB, or data processing pipelines that expect JSON input.

Testing XML APIs

When testing or exploring XML-based APIs—particularly during API integration development—quickly converting sample responses to JSON helps you understand the data structure in a more readable format than deeply nested XML. JSON objects are easier to visually scan for the fields you need than equivalent XML with namespace prefixes and attributes mixed into the tag structure.

Limitations and Edge Cases

A few structural characteristics of XML don't have clean JSON equivalents. XML supports mixed content—elements that contain both text and child elements interleaved, like `

This is important text

XML namespaces—the `xmlns:prefix` attribute declarations and the `prefix:element` naming they enable—add complexity to the JSON output because the namespace URI and prefix information need to be preserved somehow if the downstream consumer needs it. For most practical data conversion purposes, you may want to strip namespace prefixes from element names to produce cleaner JSON keys.

Free, Private, and Instant

The XML to JSON converter runs entirely in your browser. No XML data you paste in is transmitted to any server or stored anywhere. The tool is completely free with no account required, works on any device with a modern browser, and handles documents of any complexity within your browser's memory. Convert legacy XML data to modern JSON in seconds for any integration scenario you encounter.
