Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Protecting an Entire Workbook.
Excel provides a way that you can protect an entire workbook. To stop the user from taking actions such as renaming a worksheet or inserting new worksheets, you must use workbook-level protection. To protect your workbook, select Protection from the Tools menu and then choose the Protect Workbook option. This displays the Protect Workbook dialog box. (See Figure 1.)
Figure 1. The Protect Workbook dialog box.
The two check boxes at the top of the dialog box allow you to indicate exactly what should be protected in the workbook. The choices are as follows:
At the bottom of the dialog box you can specify a password to use for this level of protection. When you click your mouse on OK, Excel asks you to repeat any password you specified. If you did not provide a password, then Excel simply protects your workbook directly.
If you later want to remove the protection applied to a workbook, you do so by choosing Protection from the Tools menu and then Unprotect Workbook from the resulting submenu. If you used a password to protect the workbook, Excel displays the Unprotect Workbook dialog box. At this point, all you need to do is enter the correct password and the workbook will be unprotected.
You should note that protecting a workbook without protecting the worksheets it contains doesn't offer much protection. (Protecting worksheets is covered in other issues of ExcelTips.) The reason is that even though a user cannot delete a worksheet in a protected workbook, they can delete the information the worksheet contains. In other words, workbook protection does not protect the contents of your workbook at any level "lower" than individual worksheets.
