I am trying to compare two list to get match data but unable to get the exact result i want
sample file is uploaded please check and correct my formula
There's nothing wrong with your formula. Your data is the issue. You have V1 040 and V5 056 showing twice with 2 different customers. Index Match, like Vlookup will only take the first result.
Pls see attached file, if you don't have any issue using helper column
I have added helper column and use simple "Vlookup formula" to get desire result
