I have below set of data in excel and would like to create formula in next tab, so whenever I type dealer #, agent name should populate automatically in another tab.
Dealer # Agent
720486 AART
720548 BCCD
720962 SISI
719728 PRUF
720541 PARA
719730 PROF
720280 TOSS
721007 TFIT
720516 DOTD
720526 DHTD
Please help, thanks in advance.

Use vlookup

This will require bunch of nested formulas. There are various methods you can use. What you can do is use data validation technique. You can then use either vlookup function or index and match function. But using this along won't auto-populate the dealer name. What you need to do is use nested formula using IFNUMBER and SEARCH as well.

Avii,

you can use below formula to get the result you are looking for.
IFERROR(VLOOKUP(C3,A:B,2,FALSE),"")
Basically copy and paste the formula in column D. It will show blank if there is no value in but as soon as you enter the value, it will show you the agent name. Let me know if this help or if you need further help.

IFERROR(VLOOKUP(C3,A:B,2,FALSE),"")
A B C D
Dealer# Agent Dealer# Result
720486 AART
720491 BCCD 720491 BCCD
720496 SISI

Hi Avii, In my earlier post, I was trying to put the table in below format so it make sense. You can use this formula in any tab where you want to see the name and change the reference cell in formula, it will populate the Agent Name you are looking for. Hope this helps. Formula in D3 =IFERROR(VLOOKUP(C3,A:B,2,FALSE),"")

There are lot to watch but I liked this guy. Practice helps .

Thank you everyone for the suggestion, I am able to do so with simple VLOOKUP. For some reason there was an error on my lookup so couldn't get what I was looking for but now it is fixed.
Thanks again for your time and effort.

Someone gave me a solution book of trigonometry during my high school. I failed in 1st assessment. I gave it to my teacher then I got better and pass the final.
