Need Assistance with Extracting Component & Template Structure in JSON Format from AEM 6.5

We are trying to extract component and template structure in JSON format from AEM CMS version 6.5, we required template structure details like fields Name, field types, any datasource url which added into field and for component, we required template name along with content which used to build the respective component. Currently for Page content extraction we used JSON exporter module(.model.json) and for template extraction we tried with querybuilder => /bin/querybuilder.json?path=/conf/we-retail/settings/wcm/templates/hero-page/initial/jcr:content/root&type=nt:unstructured&p.hits=selective&p.properties=jcr:path&p.limit=-1. We would like to understand is there any direct way to fetch the response for the above requirement
