I could separate the frames, but in the file they're all directly next to each other like this so that would take quite a bit of extra work (or I'd have to code up some kind of automation for it). However all the frames in a row are the same size, as indicated by the "colour block". So for instance, the first row has a height of 52 and a width of 1900, with 38 frames. 1900 / 38 = 50 so each frame is 50x52. The dimensions of all animations can be worked out like this.
In addition, the lack of gaps is generally more useful, especially for game engines.
