Microsoft Visual Basic for Applications (VBA, Macros) when used with Microsoft Excel can build powerful automated business tools quickly and minimum cost. If you sit in front of a computer screen all day creating reports in Microsoft Excel, you know the power of this VBA software package. But if you aren't using macros yet, you don't know the half of it.
Macros automate common and repetitive keystrokes that you use in Excel to create and edit spreadsheets. By reducing the number of keystrokes required to perform common commands, macros speed up your production and reduce the time you have to spend staring at an electronic spreadsheet each day.
