Compare column of number

[Novice Lee]

Hello,
Is there a way to compare numbers in a column and return the numbers once.
Example:
a b c d e f
300 300 310 312 400 411
310
300
312
411
400
400
400

Thanks

Source data assumed running in A1 down
In B1: =IF(A1="","",IF(COUNTIF(A$1:A1,A1)>1,"",ROW()))
Copy B1 down to cover the max expected extent of source data, say down to
B200?

Then in C1:
=IF(COLUMNS($A:A)>COUNT($B:$B),"",INDEX($A:$A,SMALL($B:$B,COLUMNS($A:A))))
Copy C1 across to cover the max expected number of unique items, eg across
to Z1?. C1 across returns the results you seek. Success? hit the YES below

insted of doing the whole column how can I get it do ranges of numbers like

A4:A28, A31:A55, A58:A82, etc.....

Here's how, an example for > A4:A28 ..

In B4: =IF(A4="","",IF(COUNTIF(A$4:A4,A4)>1,"",ROW()))
Copy down to B28

In C4
=IF(COLUMNS($A:A)>COUNT($B$4:$B$28),"",INDEX($A:$A,SMALL($B$4:$B$28,COLUMNS($A:A))))
Copy across as far as required to cover the max expected number of unique
items from the source range, say to C20?
Success? hit the YES below
