Typical users engage VBA to make repeated, everyday tasks less monotonous through the use of macros. Macros automate almost any activity -- such as performing word and data processing or generating custom charts and tables. For example, a typical user might write a macro that allows them to create and fill a spreadsheet with a single click. Computer professionals use VBA and macros in more complicated ways. Programmers will often write macros that can replicate large portions of code or define specific languages.
