How to Use
- Paste or edit your JSON in the input box; it should be an object, for example {"root":{...}}
- Click the "JSON → XML" button to show the converted XML below
- Click "Copy" to copy the result in one click
- If the JSON is malformed, a specific parse error message is shown
Features
- Turns a JSON object into the matching XML tag structure, using JSON keys as XML tag names
- Automatically escapes XML special characters (& < > and friends) so the output stays valid XML
- Converts arrays into repeated sibling tags of the same name
- Reports a clear error message when JSON parsing fails
Use Cases
Integrating with legacy systems and SOAP services
Convert JSON produced by a modern service into the XML payload an older XML-based system or SOAP endpoint expects.
Generating sample XML test data
Start from a familiar JSON structure and produce matching XML fixtures for integration testing or mocks.
Migrating configuration formats
Some older frameworks require XML configuration, so convert your existing JSON configuration into the equivalent XML structure.
Learning how JSON maps to XML
Compare the same data expressed in both formats side by side to understand how the two structures relate.
FAQ
What kind of JSON converts correctly?
Use a JSON object rather than a bare array or scalar. The outermost key becomes the XML root tag, so {"root":{"item":"value"}} becomes <root><item>value</item></root>.
How are JSON arrays represented in XML?
Each array element becomes a repeated sibling tag with the same name. For example {"items":[{"id":"1"},{"id":"2"}]} produces two <items> elements.
Will characters such as &, < and > break the XML?
No. The converter escapes XML special characters for you (& becomes &amp;, for instance), so the generated document stays well-formed.
Is my data uploaded to a server?
No. The conversion runs entirely in your browser and nothing you paste leaves your machine.
