Ripping Atlas sprites?

[okay720]

So I've read online about multiple ways to rip atlas spritesheets (and animations), I tried to test ripping some using Nickelodeon HTML5 games (on FlashPoint).
No matter what method I used or what app I inserted sprites in, it'd always give me an error. 

I've tried both "Paper Battle" and "Survival of The Loudest", but none of the spritesheets/jsons allowed me to export anything.
I've noticed that all of the characters in Survival of the Loudest have 3 files, a png, a json, and a ".atlas.__gz.txt" file, none of the Atlas extractors I used allowed me to include three files,
is there no way to rip these sprites/animations, or am I missing something? The spriters resource page of Survival for the Loudest doesn't include the characters either.

(Note: "lincoln.txt" is not a txt file, its a json file, json files aren't allowed to be uploaded.)

You can find the solution from my reply to this thread -> https://www.vg-resource.com/thread-42775...#pid682132

In short, these are files from the 2d animation program called "Spine".

When loading files make sure all files have the right name and associated file endings which would be .png, .atlas, and .json (NOT .SKEL like in the other post)

Use spine version 3.6.39
