Script For fit square to art board size in Illustrator

 if you are constantly creating a square background which you should adjust to the artboard size.

I am sure Almost every time you miss one or two pixels (Retina is good for that), so we looked for a one-click feature "click object to artboard size" and here it is. Probably there is a faster way instead of inserting the exact parameters of the artboard to the square dimensions

Just download and load the script. the script will take care of the rest. (Video Guide is included)
