What you're looking for OP is most likely not "sprites" but backgrounds though. But this is your best solution for noob friendly extraction. The only drawback is that if you have to see the things you want to extract in real time, aka playing the game, and that if some background image mixes sprites & background tiles all in one, you're gonna have to combine them manually. Not really a big deal
