Please Recomend The right book for Me to learn

I deal with spreadsheets, applications, budget worsksheets everyday all based out of excel, my usual "go-to's" in excel are sorting, formulas, formating. I know how to work excel better than most people I know however I do not know much about macros and other programing. What would be a good book to get that would aid in my day to day operations? we are an insurance agency and deal with property/auto list of up to 1000 vehicles/locations and 30 page excel applicationsif that helps any.
