Export to PowerPoint, PDF and Word

Hi, Im pretty new to Bubble, and have done some research, but cant seem to find the answer, so asking here.
I want to create a webapp, where the main feature should be to export to PDF, PowerPoint and Word.
I cant seem to find an API that export to PowerPoint, any suggestions?

There is a SelectPDF plugin to generate PDFs and it is amazing on the frontend. But I would like to hear if we have a good backend alternatives - especially some custom code would be appreciated.
