I need to remove duplicate cells but besides specifying which cells
constitute a match I want to specify what to do with conflicting values in
the duplicates.

For instance one thing I'd like to do for some cells is combine/concatanate

So if I was merging on Field 1 but wanted to concatanate field 2:

Cat | Brown
Cat | White
Dog | Spotted
Dog | Striped

I'd end up with

Cat | Brown; White
Dog | Spotted; Striped

Likewise if I just wanted one value I'd like to use another field (e.g.
SourceField) to do so. So in the same instance if I wanted to merge/remove
dupes on Field 1 and use the values from Field 2 where value in Field3
(Source) = "Library"

Cat | Brown | Library
Cat | White | Wikipedia
Dog | Striped | Opinion
Dog | Spotted | Library

I'd end up with

Cat | Brown
Dog | Spotted

Are these possible with formulas?

Well, I personally wouldn't attempt it with worksheet functions, although
others might. So if you can accept a VBA solution, you're welcome to use
this one.

2 routines are provided, one for the first case you laid out, one for the
second (with 'source' considered).

To get the code to work in your workbook, open (a copy of) your workbook and
press [Alt]+[F11] to enter the VB Editor. In there, choose Insert -- Module
and copy the code below and paste it into the module presented to you. Make
any edits you need to the 'Const' values for both routines. Close the VB
Editor.

Use Tools--Macro--Macros to choose which one to [Run]. Should work for
you as long as macros are enabled in the workbook.

Here's the code.

Hi,

1. Assume the data is in D27:F30;
2. Down and install the following addin -
http://www.download.com/Morefunc/300...-10423159.html
3. In D32:D33, type Dog and Cat
4. In E32, enter the following array formala (Ctrl+Shift+Enter)

=MCONCAT(IF($D$27:$D$30=D32,IF($F$27:$F$30="Librar y",$E$27:$E$30,""),""),"
")

Hope this helps,
