Some systems and legacy APIs still expect XML rather than JSON — this tool converts JSON data into well-formed, properly indented XML in one step.
This tool converts a JSON object or array into XML, wrapping the data in a root element.
How it works
Paste a JSON object or array. The tool wraps the data in a <root> element (since XML requires exactly one root element), then converts each key into a matching child element — array items become repeated <item> elements — and formats the result with proper indentation.
- Enter jSON input.

Examples
Converting a simple object
{"name": "Alice", "age": 30} converts to an XML document with <root>, containing <name>Alice</name> and <age>30</age>.
Who should use it
- Converting a JSON API response for a system that only accepts XML.
- Learning how JSON structures map onto XML elements.
Industry applications
- Systems integration and legacy API support
- Software development
Advantages
- Produces properly indented, readable XML output.
- Automatically sanitizes JSON keys that aren't valid XML element names.
Limitations
- Uses a generic <root> wrapper and <item> naming for arrays, which may not match a specific target schema.
Common mistakes to avoid
- Expecting the output to have no root wrapper element — XML requires one, unlike JSON.
- Using JSON keys that aren't valid XML element names (like keys starting with a number) without expecting them to be sanitized.
Best practices
- If the receiving system expects a specific root element name instead of "root", rename it manually after conversion.
Tips
- If you need attributes instead of child elements for certain fields (a common XML pattern), you'll need to adjust the output manually — this tool always produces child elements, not attributes.
