XSD/XML Schema Explorer
Parse XML Schema (XSD) files and explore element hierarchies, complex and simple types, restrictions, and generate sample XML.
XSD/XML Schema Explorer
Drop or paste an XSD file and explore its structure interactively. The Elements tab shows root elements with their type annotations, cardinality, and nested children. The Types tab lists complex types (with compositor, attributes, and extensions) and simple types (with restrictions and enumerations). The Sample XML tab auto-generates a skeleton XML document from the schema with placeholder values based on each element’s type. Export the element hierarchy to CSV. Everything runs in your browser — your schema files never leave your machine.

What Is XML Schema (XSD)?
XML Schema Definition (XSD) is a W3C standard for describing the structure, content, and data types of XML documents. Where a DTD says “this element exists,” an XSD says “this element is a string between 3 and 50 characters, appears 1 to 5 times, and must match this pattern.” XSD files define the contract for XML data exchange in SOAP web services, EDI integrations, government filings, healthcare messaging, and enterprise application integration.
Why Explore an XSD?
Reading a complex XSD by hand means following references between elements, named types, extensions, and restrictions scattered throughout a potentially large file. This tool parses the schema into a navigable tree so you can see the element hierarchy, type definitions, cardinality rules, enumerated values, and validation constraints at a glance. The sample XML generator gives you a starting point for building test data that conforms to the schema.
XML Integration Services
This tool helps you understand the schema. For building systems that validate, transform, and route XML data between platforms, I build the infrastructure. See the WSDL/SOAP Explorer for exploring web service definitions, or learn about integration services. Have questions? Ask James.
