Excel, Find the first entry using VLOOKUP

Hi,

I've got two lists available. One containing IDs repeating several times, the other containing IDs appearing once only with Father's Name. I want to use VLOOKUP in such a way that only the first occurrence gets the result from second sheet.

Attaching sheet for understanding.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Saqib,


your solution would not work, if the repeated data is not consecutively ordered. for example if

2015-06-01-10-49-18-Microsoft-Excel---Fi
if A101 is repeated again after A103 then then the vlookup will return again.  

Countif is more suitable solution for this.

ProfessorJimJam, I proposed the solution for the "given" data for which it works. Your formula is good for the scenario you have considered.

BTW, may I request you to take a bit of trouble when uploading a file. If you can also paste the formula or code or whatever in the comment box it would save many from having to open your file.
