Thanks for this link, but this doesn't address the question of macros. I am familiar with embedding a traditional pptx file format. I am interested in embedding a pptm file and having it functional with the enabled macros.
Sorry I was a little hasty in posting and didn't explain what I meant. I'm not familiar with using macros on PowerPoint. What I meant to point to was the response in the other thread where the respondent was recommending using web-native Google presentations vs designed for running locally PowerPoint files. Apologies again but I don't know enough enough about Google presentations, either, in order to know if they have something akin to macros.
