Hi:
I have a workbook to consolidate expenses incurred for the month. Each type of the expenses is given a code so that I could use the Sumproduct function to sum up the total of that particular category of expenses for the month (example enclosed). However, the Sumproduct function becomes very slow to recalc when there are large number of worksheets involved. Is there any other way to achieve the same results faster?
The expenses listing worksheets are actually prepared in separate workbooks and are then copy and paste into the said consolidated workbook. Is there a way to automate this manual process for the example enclosed?
Thanks for your help in advance.
