How to add a Gaussian noise signal with zero-mean in a given data set?

I have a real-time velocity measurement data set in a excel (.xlsx) file. I want to add the Gaussian noise signal with zero mean in this real-time data to create three set of pseudo measurements. Could you please tell me how to do this in the excel sheet?

= 0.5*NORM.S.INV(RAND())
• 0.5 : can change to any non-zero number. It will control the range of the data.
• NORM.S.INV(RAND()) : produces a random number from -inf to inf, with mean zero and standard deviation 1
