Calculating Weibull in Excel

HI Forum, and a happy new year! May it be filled with millions of new renewable installations!

I wonder if someone might be able to save me hours of searching on the internet.

We've been conducting a wind survey in the province with anenometers and have alot of data which we are resuming into daily averages for each site. So there is alot data. All the calcuations are in excel, and was wondering if you can use Excel to calculate the annual or monthly weibull equation for each anenometer site i.e. Shape factor k and scale factor C.

Cheers
Larry
