I would recommend you to use any of the following options available in Denodo Platform 7.0 to represent tabular data in JSON or XML format.
1. You can use the [RESTful Web service](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/restful_architecture/restful_web_service/restful_web_service) of Denodo Platform that publishes the contents of entire Virtual DataPort server. By default, the RESTful Web service returns the data represented in HTML, but you can choose another [representation](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/restful_architecture/restful_web_service/representations) (XML or JSON) by either sending the appropriate Accept header in the HTTP request or by including the $format parameter in the URL.
1. You can publish views and associations in Denodo Platform as a [REST web service](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/publication_of_web_services/publishing_rest_web_services/publishing_rest_web_services) and choose XML and/or JSON representation in [Settings Tab (REST)](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/publication_of_web_services/publishing_rest_web_services/settings_tab_rest#settings-tab-rest) of the REST Web service.
1. You can also publish views as [SOAP web service](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/publication_of_web_services/publishing_soap_web_services/publishing_soap_web_services) in Denodo Platform but you can only represent the output data in XML format.
Hope this helps!
