Excel Lookup with IF condition?

I have Client List In ONE worksheet
Client List:
1234
2345
3456
4567

and Super Client in another Worksheet which MIGHT be the same number as a client..
1234
9876
8765
4567

In Workgroup 1 - I need to display Two Colums and MATCH the corresponding Super client..

Client - Super Client
1234 - 1234

How can I achieve this in excel? Via a lookup? Example?

vlookup() works well for this kind of thing. I have provided an example spreadsheet. The first tab has the lookup data. The setup tab uses the information and does the lookup.

How do I get rid of n/a#

Aeriden

There are a couple of ways to handle this (looking at cell B4 of the demo)...

=IF(ISERROR(VLOOKUP(A4,'Client Lookup'!$A$2:$B$28,2)), "", VLOOKUP(A4,'Client Lookup'!$A$2:$B$28,2))

This will get rid of all #N/A errors. However, you may want the errors if there is indeed no lookup found, but only if something is specified.

=IF(A4="","",VLOOKUP(A4,'Client Lookup'!$A$2:$B$28,2))

This is probably the preferred method. But thought it would be handy to know both.

What happens if I had the Super Client in one column instead of a sheet? How would i reference that... Thanks.

Aeriden

I guess I am not exactly sure what you mean... Do you mean instead of having two tabs, both are in one tab?

Yes

Here is a new version with a single tab.

Sorry for not getting back sooner and I am glad Aeriden as provided good answers while I was out.

The way VLOOKUP works is pretty simple. I could spend coming up with a great explanation but MatthewsPatrick has great article on it.

Also attached is an answer to you last question. If you award points I would give them to Aeriden.
