Excel -- Index Match array giving incorrect result

Posted on 2015-01-22

I have a formula that is intended to retrieve a list of IP addresses from a sheet named ip. The ip sheet stores the ip addresses in the second column (B). Whenever I enter the name of the server into A2 on the lookup sheet it gives me the IP address that falls one cell below the intended result.

I believe you need to adjust all of the ranges referred to from the ip sheet to starting at the same row, ie ip!$A$2, you have some starting at ip!$A$1.

I don't think the finishing rows being different is an issue in this case but worth changing those to the same as well.

As an aside, you can probably shrink the formula using IFERROR(..) rather than IF(ISERROR(..)).



In your case, (I have adjusted for all same ranges as mentioned above, but check the brackets!!):

ip!$A$1 is the header, is it still required?

Also Rob, changing the $A$2 to $A$1 generates an empty result

I was suggesting the other way, make all ranges start at A2.

You can't have ROWS in that part, Rob

Try this version, assuming you enter the formula in D2 and copy down


confirmed with CTRL+SHIFT+ENTER
