Not (practically) possible using built-in functions.

One possibility is to download the *free* add-in Morefunc.xll which has a
function (MCONCAT) that *might* do what you want.

Then you could use an array formula like this:

=SUBSTITUTE(TRIM(MCONCAT(IF(J$1:J$5=A1,K$1:K$5,"") &" "))," ",";")

Whe

A1 = a report number
J1:J5 = range of repot numbers
K1:K5 = range of languages

With 10K rows of data *expect* this to be slow!

I should mention that I'd like the output from the table below to look
something like this:

1000020 Td;Tz;Ug;Zm;Zw

1000035 Ao;Mz

etc.

Thanks - Toby

From an Access Query. I've got a list with the unique ID's for reports,
and the next field indicates what Language they were written in.

This was from a Many - Many relationship in Excel, and many of the
reports were written in many different languages.

ReportID CountryID

1000020 Td

1000020 Tz

1000020 Ug

1000020 Zm

1000020 Zw

1000035 Ao

1000035 Mz

I've got over 10,000 records like this and would like an array formula
that for each Report ID (and i've got a separate list of those of course)
provides a listing (preferably tab or semicolon delimited) of every
single country that that report covers.

Any suggestions?

Thanks - Toby
