Ok, let me explain better
As you can see in the images below, I have different files that contains all the infos I want, but these infos are stored in different files, and I need them all in ONE file.
In common they have the first column.
I need to aggregate the infos on the other files and columns all in one file.
I noted that some of this codes are not in every file, for example the code 'A03-HP851' of the second picture is not provided in the first and third file, in such case that code / line must be deleted.
Really looking forward for your help
thanks
