How to convert JSON to XML
-
1
Paste your JSON
Paste any valid JSON — an object, an array, or a nested structure — into the input box.
-
2
Set a root tag (optional)
If your JSON is a top-level array or scalar, name the wrapping root element; objects use their own keys as tag names.

3
Copy or download
Click "Copy XML" to grab the text, or "Download .xml" to save it as a file.

Quickly produce sample XML from JSON test data without writing a serializer.
Migrating configuration
Move settings stored as JSON into an XML-based config format.
Frequently asked questions
What does this converter do?
It walks your JSON and builds a matching, indented XML tree — objects become nested elements, arrays repeat an element once per item, and scalars become element text.
How are arrays represented?
Each item in an array becomes its own element using the array's key as the tag name, repeated once per item — e.g. "tags": ["admin", "user"] becomes two <tags> elements.
What happens to keys that aren't valid XML tag names?
Keys with spaces or characters XML doesn't allow in a tag name are sanitized — invalid characters are replaced with an underscore so the output always parses.
Is my data uploaded anywhere?
No. Conversion happens locally in your browser using JavaScript — nothing you paste is sent to a server.
