XML to JSON Converter Online
Convert XML data to JSON format instantly in your browser. Supports attributes, repeated elements, and compact mode. Free and private - no data is sent to any server.
What is an XML to JSON Converter?
An XML to JSON converter transforms data from XML (eXtensible Markup Language) format into JSON (JavaScript Object Notation) format. JSON is widely used in modern web APIs and applications because it is lighter, easier to parse in JavaScript, and more human-readable than XML for most use cases.
How the Conversion Works
This tool uses the browser's built-in DOMParser to parse your XML client-side and then recursively walks the DOM tree to produce a JSON representation:
- Element attributes are stored under an
@attributeskey. - Text content of leaf elements is stored under a
#textkey (or as a bare string in compact mode). - Repeated sibling elements with the same tag name are automatically grouped into a JSON array.
- Single child elements become nested JSON objects.
Compact Mode Explained
When Compact mode is enabled, simple text-only elements (elements that have no attributes and contain only text) are represented as plain strings instead of { "#text": "..." } objects. This produces cleaner, smaller JSON for typical data files but may lose precision for documents with mixed content.
Common Use Cases
- Migrating data from legacy XML APIs to modern REST/JSON APIs
- Processing RSS or Atom feeds in JavaScript applications
- Converting configuration files from XML to JSON format
- Working with SOAP web service responses
- Transforming SVG or other XML-based data for processing
FAQ
Is my XML data sent to a server?
No. All conversion happens entirely in your browser using the built-in DOMParser API. Your data never leaves your device.
Why do repeated elements become arrays?
When multiple sibling elements share the same tag name, it is the most natural JSON representation - similar to how XML lists are typically modelled. A single element stays as an object to avoid unnecessary arrays.
What happens to XML processing instructions and comments?
XML comments and processing instructions (such as <?xml ...?>) are ignored during conversion. Only element nodes, their attributes, and text content are included in the JSON output.
