XML to JSON Converter — Convert XML to JSON Online Free

What is the XML to JSON Converter?

Convert XML to JSON instantly and securely — this free XML to JSON converter is a browser-based developer tool that translates XML documents into structured JSON objects without uploading your data to any server. Whether you need to convert XML to JSON online from a SOAP API or migrate legacy RSS feeds into modern JSON APIs, this tool handles it entirely in your browser. It is designed for developers who are modernizing legacy systems, integrating with older SOAP APIs, consuming RSS or Atom feeds, or migrating data from XML-based enterprise platforms to modern JSON-based architectures.

XML (Extensible Markup Language) and JSON (JavaScript Object Notation) represent hierarchical data differently: XML uses opening and closing tags with optional attributes, while JSON uses key-value pairs and arrays. This tool bridges the two formats by mapping XML elements to JSON object keys, XML attributes to prefixed keys (using the @ convention), and repeating sibling elements to JSON arrays. The result is a valid JSON structure that faithfully represents all the data in the original XML document.

Because the conversion runs entirely in your browser using the native DOMParser API, your XML data never leaves your device. This is especially important for the XML documents developers most often need to convert: SOAP API responses containing internal system data, RSS feeds from subscription services, and enterprise data exports from ERP and CRM systems that may contain confidential business information.

How to Use the XML to JSON Converter

1. Paste your XML document into the left input panel. This can be a full XML document with a declaration, or any well-formed XML fragment. SOAP envelopes, RSS feeds, Maven files, and generic data XML are all supported.
2. The tool parses the XML using the browser’s native DOMParser, which validates the document structure. If the XML is malformed (missing closing tags, unescaped special characters, etc.), a parse error is displayed so you can fix the issue before converting.
3. Review the JSON output in the right panel. XML elements become JSON keys, element text content becomes the key’s value, and XML attributes appear as keys prefixed with @. Repeating sibling elements with the same tag name are automatically grouped into JSON arrays.
4. Check namespace handling: for XML documents with namespace declarations (like SOAP envelopes), namespace prefixes are preserved in the JSON key names. You may want to strip or remap these in your application code depending on your use case.
5. Copy or download the JSON. Click Copy to use the JSON directly in your code or API client, or Download to save a .json file. Run the output through our JSON Formatter if you need to review or reformat the structure before use.

Common Use Cases

Modernizing legacy SOAP API integrations: Many enterprise systems — banking platforms, healthcare record systems, insurance APIs — still use SOAP over XML as their communication protocol. When building a modern REST API or frontend that needs to consume data from these systems, converting the SOAP XML responses to JSON here lets you immediately work with the data in JavaScript without writing a custom XML parsing layer in your application code.

RSS and Atom feed data extraction: RSS and Atom feeds are XML documents. Podcast platforms, news aggregators, content management systems, and SEO tools need to read these feeds programmatically. Converting the feed XML to JSON makes it easy to extract fields like title, link, description, pubDate, and enclosure using standard JavaScript object property access rather than complex DOM traversal.

Android resource file migration: Android applications use XML-based resource files for strings, colors, styles, and layout dimensions. When migrating to a cross-platform framework like React Native or Flutter, or when porting to a platform with JSON-based configuration, converting these resource files to JSON provides a starting point for the migration without manually rewriting each resource file.

Data migration between XML and JSON-based databases: Legacy relational databases often export data as XML. Modern document databases like MongoDB and Firestore use JSON natively. Converting the XML export to JSON provides the input data needed to run an import script — bridging the gap between the legacy system’s output format and the new system’s input format.

Debugging SOAP and XML web service responses: When integrating with a SOAP web service and receiving unexpected results, converting the raw XML response to JSON makes the structure much easier to inspect and debug. JSON format is more readable in most developer tools and can be quickly pasted into our JSON Formatter for further review.

How Browser-Only Processing Works for This Tool

The conversion uses your browser’s built-in DOMParser API to parse the XML string into a DOM tree — the same parser your browser uses internally for all HTML and SVG rendering. Once the XML is parsed into a DOM tree, a recursive JavaScript function traverses each node: element nodes become object keys, text content becomes values, attributes become @-prefixed keys, and repeated sibling elements with the same tag are collected into arrays.

This entire process runs within the browser’s JavaScript engine, with no outbound network calls. The DOM tree is built in your browser’s memory, the conversion function runs locally, and the JSON string is written to the output panel — all without any data leaving your device.

Verify this yourself: open DevTools (F12), go to the Network tab, paste XML, and watch the JSON appear. You will see no outbound requests carrying your XML content.

Example Input

<user id="1">
  <name>Alice</name>
</user>

Example Output

{
  "user": {
    "@id": "1",
    "name": "Alice"
  }
}

Why use this offline converter?

Modernizing legacy XML payloads shouldn’t require sending data to external servers. This tool performs the entire XML to JSON translation locally, keeping your structural data and content completely private.
