XML to JSON Converter
Convert XML elements and attributes to clean JSON — runs in your browser
Paste into the left panel, upload a file, or click Sample to try it out · use Swap to reverse the conversion
Working with a REST API that needs JSON but your data source outputs XML? Paste the XML and get clean, well-structured JSON back instantly. Attributes are mapped to @ keys, text nodes to # text, and all nested elements become child objects — fully configurable.
How to Convert XML to JSON
Paste XML and download JSON in seconds — browser-only, no data sent anywhere.
Paste or upload your XML
Enter an XML document in the input panel or upload a .xml file. The converter checks for well-formedness before parsing.
Automatic JSON mapping
Elements map to JSON object keys, attributes map to @ prefixed keys, and repeated elements become arrays. Text content maps to a # text key when mixed content is present.
Copy or download
Click Copy or Download as .json. Use the result directly in your JavaScript, Python, or any language that consumes JSON.

Frequently Asked Questions
Does my XML get uploaded to a server?
No. Parsing uses the browser's built-in DOMParser API — entirely local. Your data never leaves your device.
How are XML attributes represented in the JSON output?
Attributes are mapped to keys prefixed with @. An element with an id attribute becomes a JSON object with an @id key. This convention is reversible — JSON to XML uses the same @ prefix to produce attributes.
What happens when the same tag appears multiple times?
Repeated sibling elements with the same tag name are automatically grouped into a JSON array. Three book elements inside a library element become an array of three objects under the book key.
How is text content handled?
If an element has only text and no child elements, it maps directly to a string value. If it has both, the text is stored under a #text key alongside the child keys.
Can I convert JSON back to XML in the same tool?
Yes. Click the Swap button — the tool handles both XML to JSON and JSON to XML.
What causes a parse error?
The most common causes are: missing closing tags, mismatched tag names, unescaped ampersands, or a malformed XML declaration. The browser parser will indicate the error location.
