Excel - Unique text formula
On March 30,2023 by Tom Routley
Issue
I have 2 columns of names in columns a & b and a list of dates in column c. Column A has a unique name in each cell. Column B had the same 5 or 6 names next to each name in column A.
Column C is the date the name was added to the list. I need a formula to tell me how many unique names in column a were added by a user in column B before the date in column C.
I've read on 'Count the number of unique values by using functions' & 'Count how often multiple number values occur by using functions' but can't get it. Any help offered would be greatly appreciated. Thanks in advance.

Solution
It will first sort on the name who added, then by date and then by client. If you want to see it back in old sort order, you can add rows number to each row before and once macro is done, re-sort of the row number.
But if sort is nothing big, then u can use it as is
Cells.Select Selection.Sort _ Key1:=Range("B2"), Order1:=xlAscending, _ Key2:=Range("C2"), Order2:=xlAscending, _ Key3:=Range("A2"), Order3:=xlAscending, _ Header:=xlYes, OrderCustom:=1, _ MatchCase:=False, Orientation:=xlTopToBottom, _ DataOption1:=xlSortNormal, _ DataOption2:=xlSortNormal, _ DataOption3:=xlSortNormal lrow = 2 AddedByName = Cells(lrow, 2) addCount = -1 Do While Cells(lrow, 1) <> "" If (AddedByName <> Cells(lrow, 2)) Then addCount = -1 AddedByName = Cells(lrow, 2) End If addCount = addCount + 1 Cells(lrow, 4) = addCount lrow = lrow + 1 Loop
