If you want to convert XML Schemas into JSON Schemas without any coding please see the forthcoming companion command line interface xsd2jsonschema-cli.

npm install xsd2jsonschema

const XML_SCHEMA = `
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema  xmlns:xs="http://www.w3.org/2001/XMLSchema">
	<xs:simpleType name="C">
		<xs:restriction base="xs:string">
			<xs:minLength value="1"/>
		</xs:restriction>
	</xs:simpleType>
	<xs:simpleType name="Char_20">
		<xs:restriction base="C">
			<xs:minLength value="1"/>
			<xs:maxLength value="20"/>
		</xs:restriction>
	</xs:simpleType>
</xs:schema>
`;

const Xsd2JsonSchema = require('xsd2jsonschema').Xsd2JsonSchema;
const xs2js = new Xsd2JsonSchema();

const convertedSchemas = xs2js.processAllSchemas({
	schemas: {'hello_world.xsd': XML_SCHEMA}
});
const jsonSchema = convertedSchemas['hello_world.xsd'].getJsonSchema();
console.log(JSON.stringify(jsonSchema, null, 2));

1. JSON Schema draft-04/06/07 are supported as of version 0.3.0.
2. Supports large mutli-file XML schemas with circular imports or includes, forward references, and any number of XML namespaces.
3. Preserves the original file organization in the resulting schema conversion.
4. Conversion logic has several configurable options and can be customized with your own code.
5. A companion command line interface is planned. Please see xsd2jsonschema-cli.
