Well, formulate a proper question. You never mentioned an Excel file. People aren't going to do all your work for you. Loading in an Excel file and running an fft are two completely different aspects of Matlab.
doc xlsread
can read in an Excel file and the fft documentation above shows you how to do an FFT.
Once you have tried and have some code attempting to do this it is a lot easier for people to help with specifics than for you to just expect people to do everything for you.
Matlab has some of the best documentation of any software so use it!
