What is the process for manually grouping rows in Excel?

Manually grouping rows in Excel is accomplished through the Group feature, which allows users to combine multiple rows or columns into a single adjustable unit. This feature is particularly useful for organizing large datasets, making it easier to manage and analyze data by collapsing or expanding sections as needed.

When you select the rows you want to group and then access the Group functionality—often found under the Data tab in the ribbon or through the context menu by right-clicking—you can create an expandable section that helps in navigating through complex spreadsheets.

Using the sort function does not create groups; it simply rearranges the order of the data based on specified criteria. Accessing the Formula Bar is related to editing cell contents rather than managing the layout of rows. Inserting a header row serves to label data but does not facilitate the grouping of rows for better data management. Therefore, the option involving the Group menu item correctly identifies the appropriate action for manually grouping rows in Excel.
