I have signal of 2GHz frequency recorded using an oscilloscope. i have the excel file of the signal taken from the oscilloscpe. Is it possible to use the FFT algorithm for this signal? If so how to do it?

If it is in time domain, yes you can. Just follow the example from FFT function documentation, where you change the time vector and the signal vector.
If it is in frequency domain, why FFT again.
