IconVault's XSD Generator creates a complete XSD schema from a representative sample XML document. It walks your XML and infers every element, attribute and simple type (xs:string, xs:integer, xs:decimal, xs:boolean, xs:date, xs:dateTime), detects required attributes, and computes minOccurs and maxOccurs from how often each child appears. The result is a clean, downloadable schema.xsd with proper xs:sequence and xs:complexType structure.

The more representative your sample, the better the schema: include repeated elements and optional fields so occurrences are inferred correctly. Everything runs fully in your browser with nothing uploaded, and the generated XSD can be copied or downloaded instantly. It is free to try, with a limited number of free generations before Pro is suggested.
