There are a few ways to merge cells in Google Sheets. The easiest way is to select the cells you want to merge and then go to the menu bar and select "Merge Cells" from the "Format" drop-down menu.

Another way to merge cells is to select the cells you want to merge and then use the keyboard shortcut Ctrl+M.

If you want to merge cells but keep the text in the cells separate, you can use the "Merge and Center" function. To do this, select the cells you want to merge and then go to the menu bar and select "Merge and Center" from the "Format" drop-down menu.
