About XML Schema Generator
The XML Schema Generator creates an XSD (XML Schema Definition) automatically from any XML document you provide. Paste your XML and get a complete XSD schema describing its element structure, nesting, and inferred data types.
XSD schemas are used to validate XML documents in enterprise systems, SOAP web services, B2B data exchanges, configuration file validation, and document management systems.
Data types are inferred automatically: numeric content becomes xs:integer or xs:decimal, boolean-like values become xs:boolean, and everything else defaults to xs:string.
Everything runs in your browser. Your data never leaves your device.

Examples
Practical Uses for XML Schema Generator
- Generate a starter XSD from a sample XML config file
- Create a schema to validate incoming XML from a business partner
- Document the structure of an XML export for another team
- Generate an XSD for a SOAP web service's message format
- Create a validation schema for XML uploaded by users
- Generate an XSD to enforce structure in a document management system
Who Uses the XML Schema Generator Tool
- Integration engineers generate a starting XSD from a real XML sample exchanged with a partner system.
- Enterprise developers document and validate XML message structures for SOAP web services.
- QA engineers build a schema to validate XML uploads or API responses against an expected structure.
- Systems architects generate schemas to enforce consistent XML structure in document management systems.
- Backend developers create validation schemas for XML config files without writing XSD by hand.
Comparisons
XSD vs JSON Schema
XSD (XML Schema Definition) and JSON Schema serve the same core purpose — describing the expected structure of a document — but for different data formats. XSD is the standard for XML validation in enterprise systems, SOAP web services, and B2B data exchange, with its own namespace-based syntax and long history in Java and .NET ecosystems.
JSON Schema does the equivalent job for JSON documents and is the standard in modern web APIs. If your system is migrating from XML to JSON, generating both an XSD from your current XML and a JSON Schema from the equivalent JSON is a useful way to confirm the two representations describe the same data structure.
Frequently Asked Questions
What XSD version is generated?
XSD 1.0, using the standard W3C XML Schema namespace (http://www.w3.org/2001/XMLSchema).
Does it infer data types?
Yes — numeric content becomes xs:integer or xs:decimal, boolean-like values (true/false, 0/1) become xs:boolean, and everything else becomes xs:string.
Does it handle nested XML elements?
Yes — nested elements are represented as complex types with their own element definitions in the schema.
Can I use the generated XSD to validate XML in Java?
Yes — the generated XSD is compatible with javax.xml.validation (JAXP) and other standard Java XML validation libraries.
Does it handle XML attributes?
Yes — element attributes are detected and added as xs:attribute declarations within the complex type definition.
Can I use the generated XSD to validate XML from a business partner?
Yes — generate an XSD from a known-good sample of the partner's XML format, then use it with any standard XML validator to check that future messages match the expected structure.
Does the generated XSD handle repeated elements as arrays?
Yes — when an element repeats multiple times in the sample XML, the generator infers a maxOccurs setting that allows repetition in the schema.
Can I edit the generated XSD to add stricter validation?
Yes — the generated schema is a starting point. Add restrictions like pattern, minLength, or enumeration values manually to enforce stricter rules than a single example can reveal.
