How do you merge cells in Excel?

The process of merging cells in Excel involves selecting the desired cells and then using the appropriate command found in the Home tab. Specifically, when you select the cells you want to merge and click 'Merge and Center' in the Home tab, Excel combines those cells into a single cell. Additionally, this function centers the content of the merged cells, enhancing the appearance of the data in your spreadsheet.

Other options may suggest different methods, but they do not exist in Excel. For instance, pressing Ctrl + M is not a recognized shortcut for merging cells, and simply right-clicking does not offer a direct 'Merge' option; instead, it would typically present a context menu without the merge function. Finally, the Data tab does not contain a ‘Merge Cells’ feature, making it an incorrect choice for merging cells effectively.
