Converting XML Trees to Structured JSON Data

Client-Side DOM Parsing

Your XML input is processed in your browser and is not uploaded by this tool. Tool usage events may be sent to Google Analytics without the XML content.

Extensible Markup Language (XML) remains the backbone of legacy enterprise applications, SOAP web services, RSS feeds, Android resource layouts, and financial messaging protocols. However, modern full-stack web applications and RESTful/GraphQL microservices depend almost exclusively on JavaScript Object Notation (JSON) for data interchange. Converting XML schemas into structured JSON objects allows developers to ingest, deserialize, and manipulate complex hierarchical data with minimal boilerplate.

A major technical challenge in XML-to-JSON conversion is preserving XML attributes without collisions against child element names. Pexlii can prefix attributes with @ (such as @id or @version) and place text content in a #text key when an element also has attributes. Repeated child tags become arrays, and numeric or boolean text can optionally be parsed into JavaScript values.

The converter updates its JSON preview as you edit the XML. If the browser's XML parser rejects the input, Pexlii displays the parser's error message so you can revise the text; it does not highlight a position inside the input.

How to Use XML to JSON Formatter

1

Paste XML into the input editor.

2

The JSON preview updates as you edit. If the XML is malformed, review the parser message shown below the input.

3

Review the generated JSON structure, especially attributes and repeated elements.

4

Copy or download the formatted JSON output.

Key Capabilities

Frequently Asked Questions about XML to JSON Formatter

Attributes on XML elements are extracted and prefixed with '@' (e.g. '@id': '101') so they never collide with child tags having the same name. If an element has both attributes and raw text, the text is mapped to a '#text' property.
