Edit/reverse engineer completed HTML5 ads

[blemker]

Hi, I usually use Animate to build my HTML5 ads but I was given some completed ads and asked to edit some of the pieces (the spritesheets, end card art, etc). I've searched high and low and I don't know what resources could be used for that. Because I'm mostly a visual designer, I know very little code but understanding some coding ideas. Any help or suggestions would be appreciated.

I am trying to figure out a way to edit/reverse engineer the published files as well. Some of my clients provides published files and asks for revisions. And I would have to re-produce it from scratch each time. If this is not doable it would be helpful to see the animations in a timeline.
