Once created, where can a macro be utilized?

A macro is a set of instructions that automates tasks in spreadsheet applications, allowing users to perform complex sequences of operations quickly. The correct answer indicates that once a macro is created, it can be utilized across multiple worksheets and filters in different contexts. This versatility is one of the main advantages of using macros, as they can enhance efficiency and productivity by allowing repetitive tasks to be executed without manual input.

By being applicable in various contexts, macros enable users to streamline workflows not only within a single worksheet but also across different sheets and even potentially different workbooks. This capability promotes greater reusability and adaptability, making it easier to maintain consistent processes across a broader environment.

In contrast, the other options suggest limitations that do not reflect the true functionality of macros. They highlight contexts where a macro would not be beneficial or usable, which undermines the primary advantages that macros offer in enhancing productivity and efficiency in spreadsheet management.
