Thanks everybody. As it frequently happens, things get harder when you think you're done.
I've managed to copy&paste formulas and remove the references thanks to the hints provided, programming a macro, that it should be always available as it's saved in my personal.xlsb file.
Incredingbly, when Excel is called from the WinTerm software, a new workbook ("Book1.xlsx") is created, but the personal.xlsb is not available, so the macro i programmed can't be called. If i try then to create a new macro and store it in the personal macro book, it says "Personal Macro Workbook in the startup folder must stay open for recording".
So no doubt: that software runs Excel without loading personal.xlsb
How could excel be run without loading my personal.xlsb? Moreover, if i start Excel manually, it loads personal.xlsb correctly!
Thank you very much in advance...
