No problem. In Excel, select all of the data in the spreadsheet (including the column headers), using Ctrl+A. Then click on the Data tab at the top of the Excel window, and look for an icon labelled “Sort” near the center of the Data tab ribbon. Click on the “Sort” icon, which brings up a small pop-up Window, as shown below. Make sure that the checkbox labeled “My data has headers” is checked (see #1 in the screenshot below), and then select the desired column header from the dropdown selection tool labeled “Sort by” (see #2 in the screenshot below). Then click “OK”.
