Frequently Asked Questions

What is JSON Schema?
JSON Schema is a vocabulary that allows you to annotate and validate JSON documents. It describes the structure, types, and constraints of your JSON data.
What is XSD?
XSD (XML Schema Definition) is a W3C standard that describes the structure and constraints of XML documents. It's used in SOAP services, enterprise integration, and XML validation.
Can JSON Schema be converted to XSD?
Yes. JSON Schema types map to XSD types: string→xs:string, integer→xs:integer, number→xs:decimal, boolean→xs:boolean, object→xs:complexType, array→xs:sequence with maxOccurs=unbounded.
Is my data uploaded?
No. All conversion happens in your browser. Your schemas remain completely private.
Does it support nested objects?
Yes. Nested objects generate nested xs:complexType definitions with proper xs:sequence elements.
Can I download the XSD?
Yes. Download the generated output as a standard .xsd file.
