Microsoft Excel is a spreadsheet application that is a part of the Microsoft Office software package and allows users to store data, create graphs and cheats and calculate advanced equations. When using a spreadsheet document, you can lock a single cell or more to protect the data from being accidentally deleted. You can also protect the data by creating a password that only you know in order to unlock the cell. Protecting a single cell can be done the same way for both the 2003 and 2007 versions of Excel.

Skill level:


  1. 1

    Open the Excel spreadsheet that contains that data and cells that you want to separately protect. Click on the individual cell that you want to lock.

  2. 2

    Click on the “Format” option from the top tool bar menu. Click on the “Cells” option and then click on the “Protections” tab.

  3. 3

    Click on the box next to the “Locked” field. Click on the “OK” button and you’ll be returned to the spreadsheet.

  4. 4

    Click on the “Tools” option from top tool bar menu. Scroll over the “Protection” option and then click on the “Protect Sheet” option.

  5. 5

    Type a password that will protect the cell from being unlocked by anyone else and then click on the “OK” button. The single cell in your spreadsheet will now be protected.
