Hello Frnds,


I am using 2007 excel. My file size is 21 MB. I used sumifs formulas extensively in each sheet(total 25 sheets).

My problem is whenever I open the file or close or calculate or save it takes much time say 20 min. Would like to make my workbook faster. Could you please guide me. I have some idea like:

Shall I use sumproduct instead of sumifs - sumproduct is faster than sumifs??

shall I use Pivot table and get pivot formula to get data.

or any other ways.


Please guide me.


Regards,

Vinu.

I would think a sumproduct is slower than sumifs, but haven't seen any stats either way.


First make sure the file is local and not on a network

Make sure the PC your using has lots of memory

Turn Calculation off

and Save the file

Try using a Ctrl Alt F9, this will rebuild internal spreadsheet links


Once Calculation is off you will need to force a recalculate using F9
