VLOOKUP/HLOOKUP

[Guest]

I'm going to provide as much information as possible.

I have an array of data with multiple records mapping to a single reference
ID. I am trying to create a listing of application hosted on a single
server, by server id.

Example:
Server ID ApplicationID Applicationname
1 1.1 AAA
1 1.2 AAB
1 1.3 AAC
2 2.1 BAA
2 2.2 BAB

What I want is to reverse the listing so that each server has a single
record with a horizontal listing of applications following as follows:

Server Application1 Application2 Application4
1 AAA AAB AAC

I know that this is currently not possible using either of the Lookup
functions as they will only return the first instance upon matching the
criteria. Is what I'm trying to do possible in Excel, and if so how?

Thanks.

Assumptions:

A1:C1 contains the headers/labels for the source table

A2:C6 contains the data for the source table

E1:H1 contains the headers/labels for the results table

E2:E3 contains the server ID, such as 1 and 2

Formula:

F2, copied down and across:

=IF(COLUMNS($F2:F2)<=COUNTIF($A$2:$A$6,$E2),INDEX($C$2:$C$6,SMALL(IF($A$2
:$A$6=$E2,ROW($A$2:$A$6)-ROW($A$2)+1),COLUMNS($F2:F2))),"")

....confirmed with CONTROL+SHIFT+ENTER, not just ENTER.

Hope this helps!
