Which feature allows you to automate repetitive tasks in Excel?

The feature that automates repetitive tasks in Excel is macros. Macros are a set of instructions that can be recorded or written in Visual Basic for Applications (VBA) to perform tasks automatically. This means that when you have a series of steps that you need to repeat frequently—such as formatting cells, performing calculations, or cleaning data—you can record those steps as a macro. Once recorded, you can run the macro with a single command, saving time and ensuring consistency in your work.

Macros are especially valuable in scenarios where manual execution of a task would be tedious or prone to error. By using macros, you can streamline your workflow and improve efficiency significantly.

In contrast, tables, charts, and data validation serve different purposes within Excel. Tables help organize and manage data for easy referencing and can provide structured data storage, while charts visually represent data trends. Data validation, on the other hand, utilizes rules to limit the type of data that can be entered into a cell, ensuring data integrity. None of these features offer the automation capabilities that macros do.
