Find original item id with multiple links





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I have a sheet with a large amount of item ID's in column A and in column B I have a new replacement item ID. The replacement ID can also have a replacement ID, this could be repeated up to ~20 times.



What I would like to do is in column C find the original item ID.



I have previously been able to solve it with multiple vlookup but as the file grows its getting messy and hard to manage.



Example

  • Does column A and column B (separately) have no duplicates?

Here is one formula you can use:



=IF(COUNTIF($B$1:B1,A2)=0,A2,INDEX($C$1:C1,MATCH(A2,$B$1:B1,0)))



How it works:





  • =IF(COUNTIF($B$1:B1,A2)=0,A2 - checks whether actual ID is a replacement (occurs in column B above current line), if not a replacement, than use ID as original ID


  • =,INDEX($C$1:C1,MATCH(A2,$B$1:B1,0))) - for replacement it looks for the original ID of the original item


I used a few assumptions:




  • each ID is replaced at most once (when you replace again, you replace the new ID)

  • each replacement is listed below the row containing its original ID
