Challenge: Unique Values via Formulas
Assuming that A2:A15 contains your data...
B1: leave empty
B2, copied down:
=INDEX(A2:$A$15,MATCH(0,COUNTIF($B$1:B1,A2:$A$15), 0))
....confirmed with CONTROL+SHIFT+ENTER, not just ENTER.
Hope this helps!

I was wondering if there was a way to return unique values in a column
from another column which contains duplicates. I already have a number
of macros to do this (and I'm aware of Filtering) but I was wondering if
there was a formulaic solution one might try to implement something like
this within a spreadsheet to keep this light and simple without having
to resort to these other methods. I think there should be a way.
To illustrate, say I have the following in column A:
A
A
B
C
C
D
D
D
D
E
F
F
G
G
The goal would be to return A-G IN CONTIGIUOUS cells in Column B (or
some other column). I should mention that using "helper" columns (such
as those containing the count of the value in column A for offset
purposes) would be okay, of course (as long as it's limited to a few of
them, say in B-D and my results column is D or something like that).
Thus far, I've been thinking along the lines of (for rows 2 and
greater):
Helper column B:
=COUNTIF(A:A,A2) ...[For Cell A2, and similar, copied down]
Results column C:
=OFFSET($A$1,SUM(OFFSET(B2,0,0):OFFSET(B2,(-1*ROW())+1,0)),0)
But this isn't quite doing it.
I'd love to collaborate on this, if anyone is willing.
Thanks,
