how to input a calculation in excel to find the geometric mean

IF GEOMEAN() is overflowing, then so will KL's equivalent formula.

=EXP(AVERAGE(LN(data)))
or
=EXP(AVERAGE(IF(ISNUMBER(data),LN(data))))

is a more robust calculation. Both formulas must be array entered
(Ctrl-Shift-enter). The second formula permits empty and non-numeric
cells in the data range.
