Several different ways. One way:
for no decimals:
=TEXT(A2*100,"0")
for decimals:
=TEXT(A2*100,"0.00")

Another way:
Enter 100 into a blank cell somewhere
Select the cell and copy it
Select the range containing the percentages
Edit--Paste Special
Under operation, select Multiply
Click OK

I have a number of very large spreadsheets all with percentages. I want to
change the cells from % to whole numbers. I did this the other day and it was
obviously something very simple (for me it has to be simple) but for some
reason I have gone completely brain dead and can't remember what I did.

My example is, say 12%.
When I change it to the number format I get 0.12. Obviously if I take away
the 2 decimal places I end up with 0. I want to end up with the number
displayed as 12.

Thanks in advance.
