How to get unique values in a column using excel formula

Question

I have Excel Data like below

       1001    22
       1030    6
       1031    14

       1001    3
       2344             


        

Answer 1

I think I've found a more elegant workaround without array-functions or built-in functions:

• 1^st column (ID):
  this is the array from we'd like to select distinct values

• 2^nd column (criteria): checks whether this is the first occurrence
  =IF((ROW()-1)=MATCH(A2,$A$2:$A$500,0),1,0)

• 3^rd column (cumulative):
  =SUM($B$2:B2)

• 4^th column (count):
  this is constant 1

• 5^th column (unique ID):
  =OFFSET($A$2,MATCH(ROW()-1,$C$2:$C$501,0)-1,)

• 6^th column (count):
  =SUMIF(A2:A21,F2,D2:D21)
