Generate a valid XML Schema (XSD) from any XML document — entirely in your browser. Paste your XML, choose a design pattern, and get a production-ready XSD with smart data type inference, minOccurs/maxOccurs analysis, and attribute use detection. No account, no server upload, no installation required.
Mimics the XML document structure. Elements within other elements are declared locally inside their parent's type definition. Best for simple, non-reused structures.
Disassembles the document into individual global element declarations. Parent types reference children by name using ref=. Best when the same elements appear in multiple places.
Creates named xs:complexType definitions that element declarations reference. Best for maximum type reusability and schema extensibility.
The generator automatically infers the correct XSD type from element and attribute values:
xs:integer — all values are whole numbersxs:decimal — all values are numbers (including decimals)xs:date — all values match YYYY-MM-DD formatxs:dateTime — all values match ISO 8601 date-time formatxs:boolean — all values are true/false/yes/no/1/0xs:anyURI — all values are URLs starting with http:// or https://xs:string — default fallback for mixed or text contentYour XML is parsed and analysed entirely in the browser using the native DOMParser API. No data is ever sent to a server unless you use the optional Share feature, which stores output temporarily and auto-deletes after 5 minutes.
