Step 18 of 40: Fill Series/Delete Worksheet

This step illustrates how to use the Fill Series command and how to delete a worksheet.


Q: The Account Listing worksheet is protected. What is the password to unprotect it?

A: There are two different levels of protection within Excel workbooks:

  • Worksheet protection means that only unlocked cells can be edited.
  • Workbook protection prevents you from adding, moving, renaming, or deleting worksheets. 

The Account Listing worksheet has worksheet protection applied to keep you going in the right direction. Coversely workbook protection is not enabled, because if it were you would not be able to delete the Account Listing worksheet.

Written description of the slides

The Fill Series command creates a series of numbers from a seed value that you provide. In this case, you'll enter the number 1 into cell F2, and then select cell F2. Choose Home | Fill | Series, choose Columns, and then set the Stop Value to 9 in this case, and then click OK. Based upon these instructions, Excel creates a series from 1 to 9.


To delete a worksheet, right-click the Account Listing worksheet tab and then choose Delete from the context menu. Click Delete to confirm the deletion.

TIP: You cannot undo deleting a worksheet in Excel, so pause and double-check before choosing the Delete command.
