Unlocking a Worksheet with an Unknown Password

Dennis has a travel expense worksheet that he has inherited; it has been passed down within his organization for years. Some of the cells in the worksheet need to be unlocked so that Dennis can correct the outdated formulas they contain. There is the problem, though: The worksheet is locked, and changing the formulas is not permitted because of the protection. Dennis wants to know how he can unprotect the worksheet so he can make the necessary changes.

Depending on the way that the worksheet was protected, you may be able to simply copy the worksheet contents to a new worksheet. Follow these steps:

1. Create a new, blank worksheet. This can be in the current workbook or in a new workbook.
2. Display the original worksheet that is protected. The first cell in the worksheet (A1) should be selected.
3. Press Shift+Ctrl+End. Excel should select all the used cells in the worksheet. (If it doesn't, hold down the Shift key and press the arrow keys until you have selected all the worksheet cells.)
4. Press Ctrl+C. This copies the selected cells to the Clipboard.
5. Display the new, blank worksheet you created in step 1. Cell A1 should be selected.
6. Press Ctrl+V. Excel pastes the contents of the Clipboard to the new worksheet.

The new worksheet can be changed in any way you need. If the old worksheet has links to other worksheets, you may need to copy those separately or establish those links manually. You will also need to adjust row heights and column widths, as necessary, to match the old worksheet.

If the above doesn't work, for some reason, you will need to actually try to crack the worksheet password. There are macros available, on the Internet, that will remove or identify any internal passwords, such as those used to protect a worksheet. If you do a search for "Excel password cracker" or something similar, you will find lots of candidates. The problem is that you'll also get lots of search results for programs that remove workbook passwords—something you don't need for this particular purpose.

Let me save you some trouble, however. There is a perfectly good internal password remover that is available at this page:

The page explains the macro (which is rather long) and even provides a download you can use, if desired.
