Business Budgeting and forecasting books

[Flupsie]

I am looking for a good book on business budgeting and forecasting using Excel or any online courses that someone can recommend

I studied budgeting many years ago and would like to buy a good book or attend an online course

There is so much available and one needs to make sure one buys the right book or attend an online course that will add value

It would be appreciated if someone could advise me
