If you no longer need a worksheet, or create one by mistake, you can delete it.
Right-click the worksheet you want to delete.
Select Delete from the menu.
Tip
Delete Multiple Worksheets If you want to delete more than one worksheet, press the Ctrl key, and select the worksheets you no longer want. Then, right-click and select Delete from the menu.
Caution
Excel Workbooks Require at Least One Worksheet Because Excel requires at least one worksheet, you can’t delete all the worksheets in your workbook. If you no longer need any of the worksheets in a workbook, you should delete the entire workbook instead.
