The previous section on XML and JSON responses covered simplistic examples of rendering XML and JSON responses. Whilst the XML builder used by Grails is the standard https://groovy-lang.org/processing-xml.html#_xmlparser_and_xmlslurper[XmlSlurper] found in Groovy.

For JSON, since Grails 3.1, Grails uses Groovy's {groovydocumentation}core-domain-specific-languages.html#_streamingjsonbuilder[StreamingJsonBuilder] by default and you can refer to the {groovydocumentation}core-domain-specific-languages.html#_streamingjsonbuilder[Groovy documentation] and {groovyapi}groovy/json/StreamingJsonBuilder.html[StreamingJsonBuilder] API documentation on how to use it.
