Blender remove extra egdes

So basically, I want to remove those egdes that are somtimes in rectangles that doesn’t need to be,


As shown in the picture, some rectangles have those extra edges, I can manuelly remove them by deleting them and re-adding a face, but that would take way too long, how would I do this autmatically?

You could try the command ALT+J it turns all the triangles that are selected into Quads.

Forgot I still had this topic.
Already solved it I just made a new model because it took way less time and looked better anyways
