XML to JSON Converter Online Free
Paste XML and convert it to clean JSON instantly — preserves attributes as @attributes, supports custom indentation, and runs entirely in your browser.
What Is an XML to JSON Converter?
An XML to JSON converter transforms XML (Extensible Markup Language) data into JSON (JavaScript Object Notation) format. XML uses a tree-based structure with tags and attributes, while JSON uses key-value pairs and arrays. Converting between them is a common task in web development, API integration, and data migration. This tool uses the browser's native DOMParser to parse XML reliably and maps elements, attributes, and text nodes into a clean JSON structure — all without sending data to a server.

FAQ
How are XML attributes handled?
By default, XML attributes are preserved under an @attributes key in the JSON output. For example,
What happens with repeated XML elements?
When sibling elements share the same tag name (e.g., multiple
Does it handle nested XML?
Yes. The converter recursively processes all nested elements, building a matching nested JSON structure. There is no practical depth limit.
What about XML namespaces?
Namespace prefixes are kept as part of the element name in the JSON output (e.g., "ns:element"). The converter does not strip or resolve namespace URIs.
Can I convert JSON back to XML?
This tool is one-way (XML to JSON). For the reverse conversion, look for a dedicated JSON to XML converter.
Is my XML data uploaded to a server?
No. Everything runs in your browser using JavaScript's built-in DOMParser. Your XML data never leaves your device.
