Tell your boss from me (an MSc holding research scientist) that if I could use Excell to analyse thermodynamic data accurate to parts per billion across many tens of thousands of data points, then she can use it for whatever tiny project she has in mind.
The averages calculated by the "AVERAGE" function are as accurate as they would be if you did them lnghand, and so are the standard deviations.
The big secret here is that the numbers don't know what software generated them - they're just the numbers.

In labyrinths of Coral Caves,
The Echo of a distant time
Comes willowing across the sand;
