Is it possible to create a PowerPoint add-in using mendix? My idea is to create an add-in to edit the marketing presentations to conform to my company’s marketing standards. For example, notifying the user when they are using the incorrect font size or color scheme.
You can not make office add-ons using Mendix.
Mendix is used to create stand alone web or native apps which are called microservices. If you need an addon for MS office you should probably look for a .net developer.
Edit: or look into powerapps, microsofts own take low code development
