1. Select the entire range of cells that you want to sort, excluding the header row. You can do this by clicking on the first cell of the data range and dragging down to the last cell.
2. Click on the "Data" tab in the ribbon at the top of the Excel window.
3. Click on the "Sort" button in the "Sort & Filter" section of the ribbon.
4. In the "Sort" dialog box, select the column that you want to sort by from the "Sort by" drop-down list.
5. Choose the sort order (ascending or descending) from the "Order" drop-down list.
6. Click on the "Options" button in the "Sort" dialog box.
7. In the "Options" dialog box, make sure that the "My data has headers" checkbox is checked.
8. Click on the "OK" button to close the "Options" dialog box.
9. Click on the "OK" button in the "Sort" dialog box to apply the sort.

This should sort your data without moving or touching the top row where the column header information is.
