Trying to update old Mining Spreadsheets

Well, I’m coming back to eve after a few years hiatus, and realizing that my spreadsheets, which used API, are no longer valid. I was hoping for a QUICK way to get them working again. I’ve seen a lot of things about coding and what not, but I have no idea how any of that works and just want to be able to pull market data from jita for specific items.
if anyone could point me in a direction that would be grand, thanks.
