From this XML:
<user> <id>123</id> <email>user@example.com</email> <active>true</active> </user>
Generates XSD with inferred types:
<xs:element name="id" type="xs:integer"/> <xs:element name="email" type="xs:string"/> <xs:element name="active" type="xs:boolean"/>

FAQ
What conversions does this tool support?
JSON to XML, XML to JSON, JSON formatting (beautify/minify), XML formatting (beautify/minify), and XML to XSD schema generation. All in one tool.
Is my data sent to a server?
No. All conversions happen in your browser using JavaScript. Your data never leaves your device. Check the Network tab in DevTools to verify.
How does JSON to XML mapping work?
JSON objects become XML elements, arrays become repeated elements, and primitive values become text content. Attribute mapping uses @attributes convention.
What is XSD and why generate it?
XSD (XML Schema Definition) defines the structure of an XML document. It specifies element types, required fields, and data types. Useful for API documentation and validation.
Does the XSD generator infer data types?
Yes. It analyzes your XML content and infers types like xs:integer, xs:decimal, xs:boolean, xs:date, and xs:dateTime based on the actual values.
