What is the primary use of the Group feature in the Outline Ribbon Group?

The primary use of the Group feature in the Outline Ribbon Group is to create an automatic outline of a worksheet. This feature allows users to organize and manage large sets of data by grouping rows or columns that share similar characteristics. Creating an outline helps in summarizing the information, making it easier to navigate and analyze different levels of detail within the data set. When you use the Group feature, the data can be collapsed or expanded, which provides a clearer view of the major sections, while still having the ability to drill down into the details when necessary. This is particularly valuable in financial reports or extensive datasets where maintaining clarity while still being able to access detailed information is essential.
