Macro Express is a Windows-based application that allows automation of routine functions, such as filling out web forms, opening programs, and performing mouse clicks, by means of a simple, specialized programming language with support for variables, if-then-else logic, loops and other functions.

Features include recording of the user's actions into macros, a visual programming language,^[2] sending email, window repositioning and resizing, text file processing, and file manipulation. Macros can be launched via a hotkey, or automatically triggered when a process starts or terminates, when a network connection has been made or released, when a file change occurred in a folder, or based on the contents of the clipboard.
