Is there a quick/easy way to filter all unique items in an Excel 2013 column similar to the Google Docs "Unique" function?
Use the Unique records only feature in Advanced Filter.
Under the DATA tab there is this: "Remove Duplicates". It'll do what you want.
There isn't an equivalent to =unique() in Excel, and I hate having to work without it.
Without =unique() trying to find all of the unique values in a large array of data is impossible. Take a dozen columns of a hundred+ entries and see what the unique values are across the whole mess and pop them nicely into a new columns. I can't figure out how to do it in Excel, but in Gdocs it's simple:
=unique(transpose(split(ArrayFormula(concatenate(A:M&",")),",")))
Using Filters, or PivotTables, or whatever, just doesn't cut it, and I haven't been able to find any hacked together ridiculous excel formula to do anything similar.
This is not a pretty answer, but it works. Paste this as an array formula into cell B2:
=LOOKUP(2, 1/((COUNTIF(B$1:B1, A:A)=0)*(A:A<>"")), A:A)
With the column that needs to be filtered in A:A Then drag / copy it down as far as is required.
See it online in Google Spreadsheets
Caveats:
- Does not retain original order (resulting order is in fact the reverse)
- Does not automatically expand to cover all cells
- Not fast, not pretty, not transparent
Footnotes:
- It is trivial to use IFERROR() to filter out the #N/A errors, but I've not done this to keep the answer concise
- In the same vein the header of the column A is currently also returned. This can be fixed by changing A:A to A$2:$25 in all 3 locations
- Original question was for Excel 2013, all of this should work there, but I wrote and tested it in Excel 2016
- I would love to hear suggestions on how to make the formula automatically expand down as far as required.

This might prove to be of some help to you.
