Simple algorithm in excel should do it

ExpAverage = (2/(length + 1))*close+(1-(2/(length+1)))*ExpAverage[previous day]

length is number of days average to be calculated over.

A Google search came up with these - I will let you check each one. I note at least one shows the calculation. Most free charts allow you to input a number which spits out the average for you.
