# Output first Match Found if Cells contain Duplicate Text

Suppose I have several a range of cells, each cell of which contain a string, and I want a function to look at this range and output "FALSE" if all strings in the range are unique from each other and I want it to output the first duplicate it finds if there are at least two cells with the same value. Examples of what I'm wanting:

Cells: A, B, C, D, E
Output: FALSE

Cells: A, B, C, D, A:
Output: A

Cells: A, B, C, B, A:
Output: A

Cells: A, B, C, B, D
Output: B

Is it possible to write an Excel function that does this? (It's not imperative how the 'first' match is defined; what's important is that it just outputs one of the matches.)

Try this:
Code:
``````[FONT=Lucida Console][COLOR=Royalblue]Function[/COLOR] try77(r [COLOR=Royalblue]As[/COLOR] Range) [COLOR=Royalblue]As[/COLOR] [COLOR=Royalblue]Variant[/COLOR]
[COLOR=Royalblue]Dim[/COLOR] c [COLOR=Royalblue]As[/COLOR] Range
[COLOR=Royalblue]Dim[/COLOR] z
z = False

[COLOR=Royalblue]For[/COLOR] [COLOR=Royalblue]Each[/COLOR] c In r
[COLOR=Royalblue]If[/COLOR] WorksheetFunction.CountIf(r, c.Value) > [COLOR=Brown]1[/COLOR] [COLOR=Royalblue]Then[/COLOR]
z = c.Value: [COLOR=Royalblue]Exit[/COLOR] [COLOR=Royalblue]For[/COLOR]
[COLOR=Royalblue]End[/COLOR] [COLOR=Royalblue]If[/COLOR]
[COLOR=Royalblue]Next[/COLOR]

try77 = z

[COLOR=Royalblue]End[/COLOR] [COLOR=Royalblue]Function[/COLOR][/FONT]``````

For a worksheet formula approach, try this array formula (requires Excel 2013 or later). It should be entered without the {} but confirmed with Ctrl+Shift+Enter, not just Enter. If confirmed correctly, Excel will insert the {}. The formula can then be copied down.

Edit:
(requires Excel 2013 or later)
Otherwise
{=IFERROR(INDEX(A1:E1,MATCH(TRUE,COUNTIF(A1:E1,A1:E1)>1,0)),FALSE)}

You're welcome.

(And if you would prefer to avoid the C+S+E confirmation, you can use the marginally longer ...)

For some reason your code is now a jumble of html. I put it in an html document to view it and will post a screenshot here so people can see what you wrote:

It is due to the change in forum software. We hope that in the not to distant future all these "jumbled code" posts will be converted to readable content.
