Hi guys - new and curious

Hi everybody,

I really like Excel a lot and have some smaller knowledge.
Working with it as a user about 25 years, and I am fascinated how it developed.
So its just normal, that once in a while I try some stuff, to make some of my work easier.
Unfortunately as an amateur I get often quickly eliminated by lack of knowledge.
That's why I am here to check whether it is possible to develop smaller stuff with your help.

For sure you'll find quickly a question I have :-))
Appreciate every hint, so thx in advance!

I speak English, Spanish, German and a bit Thai.
I am 55, male, work at the moment in Barcelona/Spain, but live also partly in Bangkok/Thailand or Da Nang/Vietnam.
