Open Source HTML5 Online PowerPoint Viewer?

Question

I wondered if anyone is aware of any online PowerPoint viewers that are open source? I've looked at http://www.accusoft.com/products/viewer/on-premise/info/overview/ which is the closest thing but it only works with web based documents, mine will be sitting behind an intranet firewall so now I've hit a blank. I've tried ViewerJS but this doesn't support PPT. If anyone could help me out with a js ppt viewer that is open source or has any other ideas then I would be very grateful Regards Sam

There are a few open-source options for viewing PowerPoint presentations online:

Apache OpenOffice - This is a suite of open-source office applications that includes a program called "Impress," which can be used to view and edit PowerPoint presentations.

LibreOffice - This is another open-source office suite with a program called "Impress" for viewing and editing PowerPoint presentations.

PPT.js - This open-source JavaScript library can be used to view PowerPoint presentations in a web browser. It is compatible with both PPT and PPTX file formats.

Google Slides - While this is not an open-source solution, Google Slides is a free web-based application that allows you to view and edit PowerPoint presentations online. You can upload your presentations to Google Drive and view them using Google Slides.

I hope these options are helpful.
