Applying AdvancedFilter Unique:=True to a simple column (A) values of, say, 1,1,1,1,1,2,3,4,5,6,7,7

will result in :

1,1,2,3,4,5,6,7

and NOT the required 1,2,3,4,5,6,7

Why?  Thanks, k.

Because the first 1 is considered as a field name. Change the first 1 to a meaningful name like "Numbers" and then try it.

Your comment of course works. But I find it impossible to see that can be reasonable behaviour by Excel. I have no need nor opportunity of identifying a column header - field name -  in my data. Cell A1 should be treated as any other cell in the range. Surely there must be a fully unique-compliant way of doing this?

What's more, the field header will end up in any copying of the data that I do, and I do not want that at all.

I'd go so far as to say that IMO it's one of the most ridiculous and application-defeating, lame functions I've yet seen in Excel. The fact that the Filter function has no optional header exclusion parameter is beyond belief.

You can do this in VBA and you will get the results you want:
ActiveSheet.Range("$A$1:$A$20").RemoveDuplicates Columns:=1, Header:=xlNo

Open in new window

Or just go to Data->Remove Duplicates and leave the "My data has headers" box unchecked.

HTH,
Dan

What does it mean to be "Always On"?

Well, someone at Microsoft will be happy about the next question: maybe it's time to upgrade? :)

Yeah . . .  s/one at MS is always happy I'd reckon. ;)

The fact is I'd already written my own (very long, but effective) de-dupe routine, but as it's in a sub with a load of other stuff, I wanted to make a new sub - which also will need a de-dupe routoine too -, less busy by using this AdvancedFilter option. Now that I see I can't, I'll have to use my own again. But even *that* leaves a bitter taste, as, like you said, it's all redundant if one has 2013.

This says that the RemoveDuplicates method is available since Excel 2007.
