JSON to XML Converter – Transform JSON Online
Convert JSON to XML with configurable root element and attribute handling. Our free JSON to XML Converter produces valid, well-structured XML from any JSON input.
About JSON to XML Converter
Some legacy systems and enterprise APIs still use XML instead of JSON. This converter transforms JSON data into well-formed XML with proper nesting, tag names, and attribute handling. It's useful for SOAP APIs, configuration files, and data interchange.
How the conversion works
Paste your JSON and set the root element name. Choose your indentation preference. Click Convert to XML and the tool transforms each JSON key into an XML element. Arrays become repeated elements, objects become nested structures.
Special characters in values are escaped for XML safety. Null values get an xsi:nil attribute. The output is valid XML that can be parsed by any XML processor. Use Copy or Download to export the result.
When you'd use this
You need to send data to a SOAP web service that expects XML. Or you're migrating from a JSON-based system to an XML-based one. This tool also helps when working with legacy enterprise systems that require XML input.
JSON to XML conversion is lossy in some cases. JSON's flexible structure doesn't always map cleanly to XML's rigid hierarchy. Review the output to ensure it meets your schema requirements.
Questions
How are arrays converted?
Array items become repeated elements with the same tag name. Each item is a separate element under the parent.
What about special characters?
Characters like less-than, greater-than, and ampersand are escaped as XML entities for safe parsing.
Can I customize the root element?
Yes, use the Root Element Name input to set your preferred root tag. The default is "root".
Does it add an XML declaration?
The output includes the XML declaration with version and encoding. This is required for proper XML parsing.
Can I convert XML back to JSON?
Yes, use our XML to JSON tool for the reverse conversion. Note that some XML features don't map to JSON.
