On the Data tab, in the Outline group, click Group. Then in the Group dialog box, click Rows, and then click OK. The outline symbols appear beside the group on the screen. Tip: If you select entire rows instead of just the cells, Excel automatically groups by row - the Group dialog box doesn't even open.
Can you do multiple grouping in Excel?
A shortcut way to group rows or columns is to highlight the rows/columns you wish to group and use ALT+SHIFT+RIGHT ARROW to group the rows/columns, and ALT+SHIFT+LEFT ARROW to ungroup them. You can go multiple levels as well (so you could group rows 1-30, and then group rows 20-25 as a subgroup of the first).
What does grouping cells in Excel do?
Grouping in Excel is used when we have properly structured data and with the header's names mentioned in the column. There, grouping allows users to club rows or columns of any number together so that we can hide or, in proper words, subset the data under the selected columns and rows.
