Hi,  
Need help with filtering data in columns & rows with specified email addresses.  
Ideally, I’d like to remove all the @guest.booking.com email addresses within column Email Address, and replace it with a genuine personal email address from an adjacent column Email1 (not shown in screenshot).  
The step in this screenshot doesn’t seem to be doing anything?  
Pls advise.  
Mark

@Mark_Berry Not a newbie question at all. If I’m understanding correctly, I’d use the `Add if/else column` step to create a new column with that logic (included one row of sample data to give you a sense of what I mean). The `Filter rows` step will get keep/remove any rows that match whatever criteria you provide, but I think the if/else step is actually what you need. See below for how I configured!
