This definition explains the meaning of macros.  Macros are a series of operations that are performed with a single computer instruction or command that represents a sequence of instructions or keystrokes.

Excel has a built-in macro recorder whereby processes can be recorded and macros can be assigned to a keyboard shortcut or quick access button.  The macro can then be executed whenever similar sets of data need to be formatted. It’s a nifty trick for employees who want to eliminate time-consuming tasks.
