Sometimes it is necessary to delete worksheets. Most of the time, people use only one worksheet. However, some operations create and enter data into a new worksheet. When such operations are automated, the data is not entered into an existing blank worksheet, but instead in a new worksheet. This can clutter the work area with too many worksheets. To remove a worksheet, right-click on the worksheet, and select Remove. Although the help manual says that this operation cannot be undone, it can, so don't worry about loss of data when you are doing this. It is also a good idea to allocate custom names to worksheets, to manage a large number of worksheets, or to avoid confusion. Double-click on a worksheet, and enter text to rename it.
