At what levels can embedded help be added to a workbook?

Embedded help can enhance user experience and provide guidance at multiple levels within a workbook, making it crucial for ensuring users understand the functionalities available to them.

In this case, the correct answer indicates that embedded help can be added at the workbook level, worksheet level, and column level. This approach allows users to receive contextual assistance tailored to the specific feature or data they are interacting with.

At the workbook level, help can provide general instructions relevant to the entire document, ensuring that users have a foundational understanding of the workbook's purpose and features. At the worksheet level, help can dive deeper into the specific information contained within that particular worksheet, such as instructions on how to interpret or utilize certain data. Finally, at the column level, embedded help can offer targeted support related to specific data fields, enhancing clarity and usability for users who may have questions about individual elements within the data set.

In combination, these layers of embedded help create a comprehensive support system that guides users through the complexities of the workbook, ensuring that they can effectively engage with the content presented to them.
