How to Convert JSON to XML Online — Free Guide (2026)
JSON is the modern standard for APIs, but many enterprise systems, SOAP web services, and legacy applications still use XML. Converting JSON to XML is necessary when integrating modern APIs with older systems or when XML is specifically required by a downstream service.
ToolHQ's JSON to XML converter handles the transformation in your browser with no server upload, no registration, and no installation required.
When You Need JSON to XML Conversion
JSON to XML conversion is needed in several integration scenarios:
**SOAP web services:** SOAP APIs require XML request bodies. Modern REST APIs return JSON. Converting JSON to XML bridges these incompatible formats.
**Legacy system integration:** Many enterprise systems (ERP, CRM, financial platforms) were built before JSON became standard and only accept XML input.
**Microsoft ecosystem:** SharePoint, older Office APIs, and some Azure services use XML. Converting JSON data to XML is necessary for these integrations.
**Data interchange standards:** Industry standards in healthcare (HL7), finance (FpML, FIXML), and government often mandate XML formats.
**Configuration files:** Some applications and frameworks use XML configuration files. Converting JSON configuration to XML enables use with these systems.
How to Convert JSON to XML on ToolHQ
Converting JSON to XML on ToolHQ takes three steps:
**Step 1:** Go to toolhq.app/tools/json-to-xml.
**Step 2:** Paste your JSON data into the input field or upload a .json file.
**Step 3:** Configure options (root element name, array item element name) and click 'Convert to XML'. Download the output.
The converter wraps the JSON structure in a root XML element and maps JSON keys to XML element names. JSON arrays become repeated XML elements with the same name.
JSON to XML Mapping Rules
Understanding how JSON structures map to XML helps you predict and control the output:
**JSON objects → XML elements:** ```json {"user":{"name":"Alice"}} ``` Becomes: ```xml <root><user><name>Alice</name></user></root> ```
**JSON arrays → repeated elements:** ```json {"items":["a","b","c"]} ``` Becomes: ```xml <root><items>a</items><items>b</items><items>c</items></root> ```
**JSON values → element text content:** Strings, numbers, and booleans become the text content of XML elements.
**JSON keys starting with @:** Some converters treat `@`-prefixed keys as XML attributes rather than child elements.
Conclusion
JSON to XML conversion enables integration between modern REST APIs and legacy XML-based systems. ToolHQ's free converter handles the transformation in your browser at toolhq.app/tools/json-to-xml.
Pertanyaan yang Sering Diajukan
Is the JSON to XML converter free?
Yes, completely free with no registration, no watermarks, and no file size limits.
Can I specify the root element name in the XML output?
Yes. ToolHQ allows you to set a custom root element name. The default is 'root' but you can change it to match your specific XML schema requirements.
Does the converter handle JSON arrays correctly?
Yes. JSON arrays are converted to repeated XML elements with the same tag name. You can specify the element name for array items.
Can I add XML attributes instead of elements?
Yes. Prefix JSON keys with @ to output them as XML attributes rather than child elements in the converted XML.
Is the output valid XML?
Yes. ToolHQ produces well-formed XML that validates against standard XML parsers. Note that JSON key names starting with numbers require special handling as XML element names must start with letters.
