Hello,
I can do this "join" in max 2 days. Of course my proposal can't be analytical, since I don't have enough details, but for sure I will use VBA code for this project.
A few words abut me: I'm developing VBA programs for more than 15 years and I'm a trainer for Excel, Word and VBA for 12+ years. As you can guess, I have created a plethora of VBA programs of any kind and difficulty level, for both training purposes and business.
Looking forward to hear from you,
Kind regards,
Chriskerpini
