Calculate the count without duplicates
=MAP(A2:A10,B2:B10,LAMBDA(customer,code,COUNTA(UNIQUE(FILTER(C2:C10,(A2:A10=customer)*(B2:B10=code))))))
You are welcome. This formula is a little bit shorter.
Unfortunately i don't know how we can do this with SUMPRODUCT and COUNTIFS and without LAMBDA, UNIQUE functions.
=BYROW(A2:C10,LAMBDA(y,COUNTA(UNIQUE(TAKE(FILTER($A$2:$C$10,($A$2:$A$10=TAKE(y,,1))*($B$2:$B$10=CHOOSECOLS(y,2))),,-1)))))
With Office 365 or Excel 2021 or Excel for the web you can apply this formula.
- Hi, thanks a lot.
Wow, that formula is very complex jeje. Would it be possible to do something with sumproduct and countifs for instance?
Thanks!=MAP(A2:A10,B2:B10,LAMBDA(customer,code,COUNTA(UNIQUE(FILTER(C2:C10,(A2:A10=customer)*(B2:B10=code))))))
