In as much as more people are using one and the same workbook and enter the data into a specific cell is desirable to prevent the possible change of important formulas or accidental deletion of data in the worksheet. For this purpose we use the lock cells in the Worksheet.

  • All cells in Excel are locked by default (selected options Locked) but the option is not active until you activate the worksheet protection.
  • To prohibit a possible change of certain cells need to lock them. On the sheet is necessary to unlock the cells you want to be able to change, and then activate the Protect Sheet.
  • Protect Sheet forbids that in cells that are locked can enter data or delete or modify the property and the like.
  • During lock Excel 2013 worksheet can set a password, but we do not have to if we do not want.
  • When we perform Protect Sheet in the choice we have options that can enable or disable the option Select Unlocked Cells, we are sure turn on.
  • Here in the picture above you can see another option hidden. This means that the cell to which we apply this option in the formula bar (formula field) will be prominently displayed formula or text when selected by the respective cell. It is eg used to hide the formulas that you write, and only you know to create the formula.

  • In the group commands Changes click Protect Sheet command to open a dialog window
  • In the Protect Sheet dialog box, turn on the option that you want to allow the user when working on a Worksheet.

Be sure to include the Select unlocked cells because otherwise you will not be able to work because Excel will not allow the selection of cells. Other options include optional and explore them more personally what that option means (though this is a basic tutorial for beginners).

If you want to protect the worksheet so that no one can change your settings in the Password to unprotect sheet set your secret password so that only you can make changes to the worksheet. In as much as you protect the worksheet is not too important then you can leave the Password blank and Lock the Worksheet.
