If suppose I have data like
column1 column2
504231 504109
504109 504201
504201
504299
then I used the following formula
=IF(ISNA(VLOOKUP($A2,$B$2:$B$5,1,0)),"",VLOOKUP($A2,$B$2:$B$5,1,0)) it works fine and it producess following result
column1 column2 column3
504231 504109
504109 504201 504109
504201 504201
504299
Now I have data like
column1 column2 column3
504231 504109 smith
504109 504201 scott
504201
504299
then I want ouput like
column1 column2 column3 column4 column5
504231 504109 smith
504109 504201 scott 504109 smith
504201 504201 scott
504299
**OR**
column1 column2 column3
504231
504109 504109 smith
504201 504201 scott
504299
