hello :)
I am a student majoring in computer engineering.
I am making a software that analyzes two different powerpoint files with JavaScript.
I thought it was a tree structure like a facebook React, but it seems not.
Is there any way to get differences of two ppt or pptx?

    Hi @Donghyuk Choi

    You could save the presentations as an XML and then they would be in XML format:

    Two simply view the differences, you could open them up in a Notepad editor (or do this with your JS automation).

    Example of XML:

    PPT files are binary, IIRC. There is no easy way to compare them. Especially not from JS.

    PPTX is in OpenXML format. You could open them using any one of the OpenXML libraries that are available (I assume JS has one as well) and then enumerate the OpenXML structure between the 2 files. To do that you really need to understand the structure of OpenXML and how PP uses it though.
