Hi dear list, If anybody could help me, it would be great!
I have two files: File 1 is a list (one column and around 100000 rows) File 2 is a list with all the names from file one and a few more (one column and more than 100000 rows) What I want is to add a column in file 2 that says which name appeared in file 1 and which doesn't (yes and no would work as a code) It's very important to keep the order of the names in file 2. Thank you!
