That would be Visual Basic for Applications, not the full-featured Visual Basic, if I'm not mistaken. I don't think it's possible to save out standalone executables that can run on machines that don't have Excel (or perhaps other Office apps), since its purpose is for Office automation scripting.
You are correct. But, that's about the only difference between VBA and VB. I was a VB developer for 10 years before I wrote my first VBA application (in Excel), and I was surprised when everything I tried to do in VBA just worked(TM).
