Paste any XML and get clean JSON output instantly — handles attributes, nested elements, and arrays.
Also convert in reverse with our JSON to CSV tool or format XML with the XML Formatter.
🔒 Your XML is processed locally — nothing is stored or uploaded.
@attribute keys..json file.XML and JSON are both data interchange formats, but they have very different design philosophies. XML is verbose, attribute-heavy, and hierarchical — well suited to document formats like XHTML, SVG, and config files. JSON is lightweight, natively supported in JavaScript, and easier to parse in most modern programming languages. This XML to JSON converter tool works as an XML parser, XML to JSON transformer, and legacy data converter for developers migrating systems or integrating APIs.
Developers working with REST APIs frequently encounter XML when integrating with legacy enterprise systems, government data portals, financial data feeds, or SOAP web services. Modern JavaScript frontends and mobile apps work much more naturally with JSON — fetching an XML response and wanting to use it in a React component, for example, requires conversion before the data can be rendered or processed. Converting the XML payload here and inspecting the resulting JSON structure saves time when writing the actual parsing code.
Data engineers use XML-to-JSON conversion when migrating data between systems. A database export in XML format needs to become JSON before it can be imported into a MongoDB collection or processed by a Python data pipeline. Converting a sample first confirms the structure maps correctly — that element nesting becomes object nesting, repeated elements become arrays, and attributes are preserved rather than lost. The download option makes it easy to save the converted output directly for use in the next pipeline stage.
The conversion handles XML attributes by prefixing them with @ in the JSON output, which is the widely used convention for representing XML attributes in JSON. Repeated sibling elements at the same level are automatically converted to JSON arrays. All conversion runs entirely in your browser — no XML is ever sent to a server.
