Switch calculating cells off

A

Al

I'm using a massive workbook. Everytime I do anything, the entire workbook
has to re-calculate every formula. This takes too long for me, to have to
wait after every small amendment I make, or after every new cell is updated.

Can I switch off the calculation whilst I make my changes and then swith it
back on again, when I am ready?

You can go to Tools -> Options -> Calculation -> Uncheck the the automatic
calculation or choose manual calculate.

Then press F9 to make the whole book calculate. Or press Shift+F9 (i think)
to only calculate the active sheet.
