  • Check the box next to “Show error alert after invalid data is entered” if you want Excel to display an error message when someone tries to enter invalid data.

To unlock the cells, simply go back to the “Data Validation” window and remove the validation rule.

Lock cells using a formula:

Another way to lock cells in Excel is by using a formula. This method can be used to lock cells based on the value of another cell. For example, you can lock a cell if the value of another cell is greater than 100. To use a formula to lock cells, follow these steps:

  • Select the cell you want to lock.
  • In the formula bar, enter a formula that evaluates to “TRUE” or “FALSE.” For example, “=A1>100” would evaluate to “TRUE” if the value in cell A1 is greater than 100, and “FALSE” if it is not.
  • Press “Enter” to apply the formula.
  • Right-click on the cell and choose “Format Cells.”
  • In the “Format Cells” window, go to the “Protection” tab.
  • Check the box next to “Locked.”
  • Click “OK.”

With this method, you can lock cells based on the value of another cell. To unlock the cells, you will need to remove the formula from the cell.
