Calculate the count without duplicates
I am looking for a formula to calculate the count without duplicates for unique combinations of "Country," "Code," and "Serial" The result for country Mexico and Code 0014 should be 4 because it...

I'm sorry but i see no limitations which could prevent to use nested IF. The only point it is a bit less flexible compare to nested If equivalents.
But what to use depends on goals, in some cases quick hardcording works quite fine.
If use formatting nested if becomes much more clear and editable. Like this
=IF(ISNUMBER(SEARCH("Sales", B3,1)),"Sales",
IF(ISNUMBER(SEARCH("Arch", B3,1)),"Architecture",
IF(ISNUMBER(SEARCH("Land", B3,1)),"Land",
IF(ISNUMBER(SEARCH("All", B3,1)),"All",
IF(ISNUMBER(SEARCH("Contracts", B3,1)),"Contracts",
IF(ISNUMBER(SEARCH("Construction", B3,1)),"Construction",
"No Match"
))))))
If instead of hardcoded strings use references nested IF becomes more flexible. And if add some extra references (nested if) for future strings to find it becomes even more flexible.
=IF(ISNUMBER(SEARCH($F$1,B3,1)),$G$1, IF(ISNUMBER(SEARCH($F$2,B3,1)),$G$2, IF(ISNUMBER(SEARCH($F$3,B3,1)),$G$3, IF(ISNUMBER(SEARCH($F$4,B3,1)),$G$4, IF(ISNUMBER(SEARCH($F$5,B3,1)),$G$5, IF(ISNUMBER(SEARCH($F$6,B3,1)),$G$6, IF(ISNUMBER(SEARCH($F$7,B3,1)),$G$7, IF(ISNUMBER(SEARCH($F$8,B3,1)),$G$8, IF(ISNUMBER(SEARCH($F$9,B3,1)),$G$9, "No Match" )))))))))
I don't vote for nested IF, i would like to say where is no limitations here. What to use that's concrete person choice.

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))))))
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.
