But why when I checked the number of threads of Excel in Windows Task

Excel is a process with multiple threads. ?? thanks again

Wouldn't being event-driven virtually require being multi-threaded? I
would guess you would need at least one monitoring thread. Calculation
and screen-updating seem to take place in different threads sice the
screen seems to update *while* calculation is going on - but this may
be an illusion.
