One more option: How about a UserDefinedFunction?

It uses the almost the same syntax as the =vlookup() function. But it always
uses "false" as the 4th argument--no matter what you type.

Select a range (single column/single row) with enough cells to fill in your data
(any cells not used will appear empty).

Then type in your formula:

=mvlookup2(a1,sheet2!$a$1:$c$999,3,false)
(mvlookup2 = multiple Vlookup)
(2 because this one is different from my original. You can change it (all
spots) if you want to.

I have a list of contract numbers (column A) and associated account numbers
(column B). Some contract numbers are listed more than once because there
may be multiple associated account numbers.

My goal is to have one row/record for each contract number, with all the
associated account numbers in a single cell, comma delimited.

Can Excel do this?
