About the XML to JSON Converter

XML has been a standard data interchange format for decades. SOAP APIs, enterprise configuration files, RSS and Atom feeds, SVG graphics, and countless legacy systems produce XML output. Modern applications and APIs overwhelmingly prefer JSON. This converter takes any valid XML document and transforms it into a structured JSON representation, saving you from writing custom parsing code.

The conversion happens entirely in your browser using the native DOMParser API. No data leaves your machine, so you can safely convert XML that contains proprietary schemas, internal configuration, or sensitive data.

How to Use the Converter

Paste your XML into the left-hand editor. The JSON equivalent appears instantly on the right. The root XML element becomes the top-level key in the JSON object. Child elements become nested objects, repeated siblings become arrays, and attributes are stored under @attributes. Copy the result and use it in your application.

Features

  • Attribute preservation. XML attributes are stored under a dedicated @attributes key so they are not confused with child elements.
  • Automatic array detection. Repeated sibling elements with the same tag name are automatically converted to JSON arrays.
  • Nested structure support. Deeply nested XML hierarchies are faithfully represented in the JSON output.
  • Error reporting. If your XML is malformed, the converter displays the parser error so you can fix it before retrying.
  • Client-side processing. Everything runs locally in your browser. No server round-trips, no data collection.

Common Use Cases

Developers integrating with SOAP web services often need to convert XML responses into JSON for use in JavaScript or TypeScript applications. Data engineers migrating legacy XML exports to modern data pipelines can use this tool to inspect the structure before writing transformation scripts. And anyone working with RSS feeds, sitemap XML, or configuration files in XML format can quickly see the data as a JSON tree, making it easier to plan how to consume it programmatically.

Frequently Asked Questions

How are XML attributes handled in the JSON output?
XML attributes are grouped under an "@attributes" key in the corresponding JSON object. For example, becomes {"@attributes": {"id": "1"}}. This keeps attributes separate from child elements so you can distinguish between the two in your code.
What happens with repeated XML elements?
When multiple sibling elements share the same tag name, they are automatically grouped into a JSON array. For example, multiple elements inside a parent become an array under the "item" key. Single elements remain as plain values.
Are XML namespaces preserved?
Namespace prefixes are kept as part of the tag names in the JSON output. For example, becomes a key named "soap:Envelope". Namespace URIs declared via xmlns attributes appear under the @attributes key like any other attribute.
Can I convert large XML files?
The converter runs in your browser using the built-in DOMParser, so it can handle files of moderate size without issues. For very large XML documents (tens of megabytes), you may experience slower performance depending on your browser and device. There is no hard size limit imposed by the tool itself.
Does the converter handle CDATA sections?
Yes. CDATA sections are treated as text content by the browser's XML parser. The text inside CDATA is included in the JSON output as a regular string value, with no special wrapper.
