  1. Select the cells that will be unprotected

  2. Select Format - Cells - Cell Protection. Unmark the Protected box and click OK.

Sheet protection also affects the context menu of the sheet tabs at the bottom of the screen. The Delete and Rename commands cannot be selected.

If a sheet is protected, you will not be able to modify or delete any Cell Styles.

A protected sheet or cell range can no longer be modified until this protection is disabled, with the exceptions of the settings for columns and row of the Tools - Protect Sheet dialog. To disable the protection, choose the Tools - Protect Sheet command. If no password was set, the sheet protection is immediately disabled. If the sheet was password protected, the Remove Protection dialog opens, where you must enter the password.

Once saved, protected sheets can only be saved again by using the File - Save As command.


Complete protection of your work can be achieved by combining the options Tools - Protect Sheet and Tools - Protect Spreadsheet Structure, including password protection. To prohibit opening the document altogether, in the Save dialog mark the Save with password box before you click the Save button.
