Remove one excel data from another.



Could anyone help me with my issue?


I have one big sheet of Excel with data let's call it "A"  ( there are some information concerning customers e.x Name, Surname, address, client number and so on). 

I also have small data of another Excel sheet let's call it "B"  and here are some customers that may or may not be included in this first sheet. 

Now I have to get rig of customers that are included in Excel sheet ( B ) from the Excel sheet ( A ) in other words delete them.

The outcome of this process should be A - B.

How can I do it with Knime. 


I tried with Joiner but I have to do something wrong or this is wrong idea.

Hi, you should try the Reference Row Filter.
