XML to JSON Converter
This XML to JSON converter transforms XML documents into JSON and back. Handles attributes, nested elements, and sibling arrays.
About XML to JSON Converter
The XML to JSON Converter is a free browser-based tool that transforms XML documents into JSON format and back. It uses the browser's native DOMParser for reliable XML parsing without any external dependencies.
XML to JSON Conversion
Paste XML into the left pane and click "XML to JSON" to get a structured JSON representation. The converter handles attributes (prefixed with "@"), text content (using the "#text" key when mixed with other elements), nested elements at any depth, and sibling elements with the same name which are automatically grouped into arrays.
JSON to XML Conversion
The reverse direction follows the same conventions. Properties starting with "@" become XML attributes, arrays become repeated child elements, and the "#text" property becomes text content. The generated XML is properly indented and formatted for readability.
Syntax Highlighting and Error Handling
The JSON output includes color-coded syntax highlighting that distinguishes strings, numbers, booleans, keys, and null values at a glance. If your XML contains syntax errors, the tool displays a clear error message from the browser's parser to help you find and fix the problem quickly. Once you have JSON, you can clean it up with the JSON formatter or convert it further with the JSON to CSV converter.
All processing happens entirely in your browser. No data is sent to any server, making this tool safe for converting sensitive XML files such as configuration files, SOAP responses, or data exports from enterprise systems.
Frequently Asked Questions
How does the converter handle XML attributes?
XML attributes are converted to JSON properties prefixed with the "@" symbol. For example, <book id="123"> becomes {"book":{"@id":"123"}}. This convention keeps attributes visually distinct from child elements in the JSON output, and it is a widely used pattern in XML-to-JSON conversion.
What happens with repeated child elements of the same name?
When an XML element has multiple children with the same tag name, they are automatically grouped into a JSON array. For example, <items><item>A</item><item>B</item></items> becomes {"items":{"item":["A","B"]}}. This ensures the structure is preserved accurately.
Can I convert JSON back to XML?
Yes. The tool supports bidirectional conversion. Paste JSON in the right pane and click "JSON to XML" to generate XML output. The converter follows the same conventions in reverse - properties starting with "@" become attributes, arrays become repeated sibling elements, and the "#text" key becomes text content.
What XML parser does this tool use?
The tool uses the browser's native DOMParser API, which is the same parser browsers use to process web pages. This means it handles well-formed XML reliably without any external libraries. If your XML has syntax errors, the parser will report them clearly so you can fix the issue.
Is my data processed on a server?
No. Everything runs in your browser using JavaScript and the native DOMParser. Your XML and JSON data never leaves your machine, so you can safely convert files that contain sensitive configuration, API responses, or proprietary data.
