Hi TIm:
We will use a combination of COUNIF() in a helper column and Autofiltering:
Say our data (in Cols A&B) is:
size type
large dog
medium dog
small dog
large cat
medium cat
small cat
large bird
medium bird
small bird
large fish
medium fish
small fish
tiny ant
in C2 enter:
=COUNTIF($A$2:A2,A2) and copy down column C, resulting in:
size type helper
large dog 1
medium dog 1
small dog 1
large cat 2
medium cat 2
small cat 2
large bird 3
medium bird 3
small bird 3
large fish 4
medium fish 4
small fish 4
tiny ant 1
Then turn on autofilter and pick 1 for column C
