Visual Basic
From Just Solve the File Format Problem
Visual Basic is a Microsoft programming language based on BASIC, but evolved far enough from early BASICs to be pretty much unrecognizable to anybody acquainted with such languages as Applesoft BASIC. It has an event-driven structure and support for graphical user interfaces.
Visual Basic for Applications (VBA) is a variant of Visual Basic that is used embedded in an application software package; this is what is used for Microsoft Excel macros in XLM, XLSM, and XLTM files.
