PDF Thumbnail Labels into a List

[Rymare]

I have a giant PDF and I want a list of the thumbnail names--in just a text list--so i can use it in a macro I have.

So, I want this:

Into this

D22
D23
D24
E22
E23

etc. etc.


Now I only have the adobe reader DC, none of the frills and very basic, and I don't need any images or anything--literally just a list of the page thumbnail labels. I tried simply dragging my mouse up the list to just copy the text, but adobe reader DC won't let me do that. Command Line, PowerShell, VBA--doesn't matter what the solution is, I'm willing to try anything, I've been banging my head against this issue for days.

Any help is super duper appreciated!
