I would encourage you to enable swagger and see what excel-reports options exist, and see if they fit you needs.
swagger can be enabled by setting "swagger.enabled=true" in your env.properties file, restarting (or starting) Mango, and navigating to http://[ip:port]/swagger
Thank you a lot for telling me about excel-reports. It works very well and I managed to create a satisfying template to show the information that I want to. There is only one problem. This is my first web programming project, so please bear with my silly questions, but how would I go about making a button on a website run the report and then download the report that was created.
