About XML to XSD Converter

Our free XML to XSD Converter automatically generates XML Schema Definition (XSD) files from your XML documents. Simply paste your XML content, and our tool will analyze the structure and create a corresponding XSD schema that defines the rules and constraints for your XML data.

The converter intelligently infers data types (string, integer, decimal, boolean, date, dateTime), handles nested elements, detects repeating elements, and processes attributes to create a comprehensive schema definition.

Elements

Attributes

What attributes elements can have and if they are required.

Data Types

The type of data (string, integer, etc.) each element can contain.
