About This Tool

This tool provides bidirectional conversion between XML and XSD, enabling users to generate a valid XSD from an XML instance or create an XML instance from an XSD. It targets developers, data architects, and QA engineers working with XML-based data exchanges. The engine analyzes input structures, preserves namespaces, and infers types to produce robust schemas or representative instances. In XML_to_XSD mode, complexType and simpleType definitions are derived from element and attribute patterns, with occurrence constraints mapped from minOccurs/maxOccurs. In XSD_to_XML mode, a compliant XML document is assembled from the schema's element declarations and namespace information. Core features include mode selection, optional validation controls, namespace preservation, and the ability to export the resulting artifact. The tool aims to shorten data modeling cycles, improve consistency across environments, and provide a concrete artifact for testing and integration.

How to Use

  1. Provide inputs: paste XML or XSD content and select the conversion mode.
  2. Choose mode: XML_to_XSD or XSD_to_XML.
  3. Configure options: enable validation, preserve namespaces, set strict inference.
  4. Run conversion: submit to generate the target document.
  5. Review and export: copy, download, or validate the result.

Frequently Asked Questions

Find Quick Answers

What can I convert with this tool?
The tool can generate an XSD from an XML instance or produce an XML instance from an XSD. It supports common XML structures and preserves namespaces by default. Some advanced XSD 1.1 features may not be fully represented.
Is the output validated?
Validation checks can be enabled to assess basic structural conformance against the input. The tool does not replace a full XML validator; use a dedicated validator for production-grade validation.
Will namespaces be preserved?
Yes, there is an option to preserve input namespaces in both directions. If disabled, the tool will generate namespace-neutral samples while maintaining valid structure.
Can I export the results?
Yes, the generated artifact can be copied to the clipboard or downloaded as a file. Outputs are designed for quick integration into development and testing workflows.
