Question

In my two columns of data I would like to keep only the unique values of ColumnOne that have the highest value in ColumnTwo.

For example

ColumnOne       ColumnTwo
2                  6
3                  2
7                  8
2                  7
3                  4
7                  3

So in this example my output would be:

      2                  7
      7                  8
      3                  4

because this is the unique values in ColumnOne with the highest values in ColumnTwo.

I tried using the formula

    "=IF(COUNTIF($A$2:A2,A2)>1,[ IF(B2>____  )1,0 ], 0)"

but I am stuck on what to put in this portion

   "IF(B2>____)."

This is what I am trying to say in the function:
If the value in the first column is repeated more than once

1. Than if the corresponding B column has a greater value PRINT 1 ELSE PRINT 2

2. *Else*Print 0

Any help would be really appreciated, Thanks!

Answer 1

Based on the original data you could put this formula in C2

=(B2=MAX(IF(A$2:A$7=A2,B$2:B$7)))*(SUM(IF(A$2:A2=A2,IF(B$2:B2=B2,1)))=1)

confirmed with CTRL+SHIFT+ENTER and copied down

That will place a 1 against the first instance of each row containing the MAX B value for each distinct A value, zero otherwise.

You can filter by 1s in column C to see just those rows
