What is a macro in Excel?

A macro in Excel is defined as a set of instructions that automate repetitive tasks. This functionality allows users to record a series of actions performed in Excel and then play them back later with the click of a button or a keyboard shortcut. This automation saves time and reduces the potential for errors that can occur when performing the same tasks manually multiple times.

Macros are particularly useful for tasks such as formatting a report, creating charts, or applying complex formulas across multiple cells or datasets. By creating a macro, users can streamline their workflow and enhance their productivity, making it easier to manage large quantities of data or perform routine operations efficiently.

In contrast, other options focus on different aspects of Excel that do not align with the core functionality of macros. Manual data entry involves inputting data by hand, visual representations pertain to charts and graphs, and creating complex formulas is about formulating calculations rather than automating repeated actions.
