newdoverman, I appreciate the quick response. I was able to plugin my data, comparing 2000 rows to an index of 7000 rows, to your spreadsheet and was able to modify the formula in column C to identify the unique rows in column B. Forgive my beginner knowledge of Excel, but I am having difficulty modifying the formula in column F to list any more than 25 unique rows from column B.

Here is the modified formula from C2, which seems to be working:
=IF(COUNTIF($A$2:$A$7810,B2)>0,"",MAX($C$1:C1)+1)

This is the modified formula from F2, which is only returning 25 unique rows from B:
=IFERROR(INDEX($B$2:$B$2362,MATCH(E2,$C$2:$C$2362,0)),"")

I also just noticed that column E is only enumerated to row 26 even though column C identifies 324 unique rows.

I am sure that I am missing something simple, but as I said my untrained eye is blind tonight. Thanks, in advance for your help.
