XSD from XML

The tool derives a standards-compliant XML Schema (XSD) from a representative XML sample. It is used by developers, data architects, and API integrators who need a formal, machine-usable schema to validate, document, and integrate XML data. The output supports validation pipelines, code generation, and documentation. When multiple XML samples indicate divergent types, the tool records ambiguities and suggests type-casting options for user review.
Conceptually, the tool parses the XML sample to identify element names, attributes, and repeating groups; it infers basic data types using deterministic or heuristic rules; it maps sequences and choices into xs:sequence and xs:choice; it assigns minOccurs and maxOccurs based on observed multiplicity. It can emit annotations and documentation and preserves namespaces when provided, allowing declarations as global or local elements where appropriate.
Unique value comes from automatic inference that supports both simple and complex types, handles namespaces when provided, and yields a schema suitable for API contracts, data migrations, and data quality checks. It supports advanced options like target namespace, global elements vs local, and generated documentation annotations; users can export or copy the schema for reuse. Typical workflows include schema-driven validation in CI, API contract-first development, and rapid data modeling for integration projects.
