how can I load an existing pptx file? Our customers would like to create a master pptx file with their own coporate branding. They are users and not developers. Is it possible?
Thanks.

You can't do it with PptxGenJS, as you can see it is listed as a feature they will not be implementing:

If your data does not have to be in pptx format, then you can reproduce an HTML table and use it within PptxGenJS:
