Here's one easy ways (assuming you have a column heading):

Use a Pivot Table
Set ROW to your_col_heading
Set DATA to Count of your_col_heading

Does that help?

Cell B1: =A1
Cell B2: =IF(ISERROR(MATCH(0,COUNTIF(B$1:B1,$A$1:$A$20&""),0)),"",
INDEX(IF(ISBLANK($A$1:$A$20),"",$A$1:$A$20),MATCH(0,COUNTIF(B$1:B1,$A$1:$A$2
0&""),0)))

enter as an array formula, commit with Ctrl-Shift-Enter, then copy down

Cell C1: =IF(B1<>"",COUNTIF(A:A,B1),"")

and copy down
