How to Protect Sheets in MS-Excel?

If you keep your files in the office or any other shared computers, chances are there that others may access your files and make alterations or deletions.  You have created an Excel file with sensitive data having some special formulas and for which you have taken so much time and effort to create it.  If you lose any number or formula the whole sheet will have no use and creating the same may take time.

There may be data which you have to show or share to other employees including your boss but at the same time you need to protect them from any alteration or deletion.  There is an option to protect your MS-Excel sheets, follow the steps below:

  • Open the file à Select your particular sheet
  • Right Click on the Mouse à you can see an option ‘Protect Sheet’

protect sheet1


  • Select ‘Protect Sheet’ à a pop up window will appear named ‘Protect Sheet’


protect sheet2


  • Check the option ‘Protect worksheet and contents of locked cells’ at the top
  • Type the password in the space provided just below ‘Password to unprotect sheet’ à click ‘OK’
  • Another window 'Confirm Password' will open and ask you to ‘Reenter password to proceed’ 
protect sheet3



(Remember if you forget the password, you cannot recover it) à retype the password and click ‘OK’

The sheet is now protected.  You can also check the options to allow users to do some functions like ‘Insert rows or columns’, ‘Delete rows or columns’, ‘sort’, etc (see picture No.2).
