Welcome to! My aim is to help you learn MS Excel including VBA. I always felt that a good way to learn something was to find solutions to problems in that domain. That is why I share these Excel videos with you. Mostly these are questions asked during my corporate training sessions. I've been training individuals and companies in computers since 1991. I did my B. Sc. (Vordiplom), M. Sc. (Diplom) and Ph.D. (Dr. rer. nat.) from Hamburg, Germany. The best thing about solving some of my visitor's questions is that I also gain new insights.
