Don’t know if anyone else here has mentioned it, but there is a JavaScript object model that you can call against https://learn.microsoft.com/en-us/office/dev/add-ins/powerpo... And a reference for that https://learn.microsoft.com/en-us/javascript/api/powerpoint?... I was involved in a project where we were trying to use all of this to build PowerPoints and Word documents programmatically and in the end we moved to a simpler approach (this was before LLM times). But knowing how the PPTX is constructed is a useful starting point for anyone.
