Hi everyone, in the attached example, in cell (E11), I want to count unique customers which purchased product 1, their area code matches with the corresponding code in cell (D11), and only purchased less than 5 units
I use the following array formula:
=SUM(IF(FREQUENCY(IF($G$2:$G$7=D11,IF($I$2:$I$7="Product 1",IF($J$2:$J$7<5,IF($E$2:$E$7<>"",MATCH($E$2:$E$7,$E$2:$E$7,0))))),ROW($E$2:$E$7)-ROW(G2)+1),1))
It works perfectly, but when using this formula through huge database which contains tons of customers, product& areas. Excel take very long time to calculate this function in a table column consists of +1000 cells, It takes about 10 minutes to calculate only one column which is possible to continue like that
Is there any way to convert this Array function into regular one by using helper columns or whatever to avoid all this time waiting for calculations
Any help will be appreciated to the maximum, thanks a lot in advance
