I have two .csv-files, master.csv and slave.csv, and I need to compare those two and get the difference to output in a file.
The master.csv-file contains the up-to-date entries and slave.csv contains the entries that are "active" and need to be updated.
In master.csv there might have been entries added or removed and I need the diff in two files, lets say master.added.csv and master.removed.csv and in those files there are Only the entries that got added/removed and nothing more.
Is this possible?
Let me explain this in a little more simpler way.
To in this case I should get these files:
I hope you understand what I'm looking for. Is this possible?

Yes, you can do it, and if the data are in the same format in both files you can do it quite easily I suppose.
I would try to handle the files as plain text. Loading them in memory and comparing them.

If you have any problems implementing this, let me know.
