How to save Sims data when wiping Mac?

I have to wipe my Mac as I've been having performance issues with it. I thought my Sims data would be saved in the EA app, but luckily, I looked it up first, and I saw it's saved locally on my computer. I've been playing with the same family for over 2 years and would be extremely upset to lose that data. How do I make sure to keep it? Thanks so much!
