For me, Excel is like the software version of a Swiss armyknife. I do all kinds of stuff with it and think it's really useful. Combined with my iPaq 2210 it makes a killer combination that I use daily.
However, I feel that they've stripped Excel a little too much, some functionality and many functions I frequently use are missing (for the moment I would have liked the DAYOFWEEK function but there are more functions I miss).
Before doing my own versions of the most missed functions I have to ask; is there any add-on or perhaps a good source of information regarding writing your own formulas, something that would help me doing or even spare me the work...?
Well, calculating weeknum was (of course) rather simple but there are functions I still miss and functionality as well.
For instance, why - just why exclude the possibility to copy a sheet? Create them, delete them, rename them and move them, but not copy them? Makes no sense to me. *annoyed*
