I have a daily file that I generate everyday, the issue is that it is a snapshot. So I created a file where I merge all info together, I would like to create an append to existing file, that whenever I add the snapshot data to that file, in a “Created Date” column of the “big data” file, it puts the timestamp of that snapshot.
this way I could see what data was added and in which day. Is this possible?
Thank you very much in advance.
