JSON input
{
"user": {
"id": 42
}
}What this tool does
JSON to XML rewrites structured JSON into XML markup. That is helpful when modern app data needs to move into an older integration, vendor import, or standards-based system that still works with XML.
Because XML and JSON model data differently, the goal here is practical conversion for common objects and arrays, not pretending the formats are identical.
Common use cases
- Converting modern payloads for legacy integrations.
- Generating XML exports from JSON-based app data.
- Testing how a JSON structure maps into XML elements.
- Bridging between document-style and API-style data workflows.
Input and output example
XML output
<?xml version="1.0" encoding="UTF-8"?> <root><user><id>42</id></user></root>
How to use this tool
- Paste valid JSON into the input panel.
- Click Convert to XML.
- Review the generated XML and copy or download it.
- Use XML to JSON if you need to go back the other way.
Your JSON is processed in your browser and is not uploaded to our servers.
Common errors
- Invalid JSON blocks the conversion completely.
- Arrays become repeated XML items, which may not match every third-party schema.
- Some JSON structures do not have a perfect XML equivalent.
- Special characters must be escaped properly in XML output.

FAQ
Does XML preserve the same structure as JSON?
It preserves the data in a common structural way, but JSON and XML are not exact one-to-one formats.
Can I convert arrays?
Yes. Arrays are represented as repeated XML item elements.
Can I download the XML file?
Yes. Generate the output and download it as an XML file.
Is this useful for old enterprise systems?
Yes. That is one of the most common reasons to convert JSON into XML.
