Lock Cells in Excel

Lock Specific Cells| Lock Formula Cells

You can lock cells by using Excel’s built-in options. Locking a cell protects it from being edited by other users. We have divided this tutorial into three different sections: lock all cells, lock specific cells, and lock formula cells.

Lock All Cells

If you protect your worksheet, all cells become locked by default. Let’s follow the steps below.

1. Select all cells.

select all cells

2. Right click and select Format cells (keyboard shortcut: CTRL + 1).

3. Click on the Protection tab and check the Locked box.

4. Click OK or Cancel.

5. Now, Protect the sheet because locking cells has no effect until you protect the sheet.

Note: If you want to unprotect the cells, simply follow the steps of unprotecting sheet. (Hyperlinked) The password we used to unprotect the sheet is “protect”.

Lock Specific Cells

If you want to lock specific cells instead of locking the whole sheet, you need to unlock all cells first. Here are the steps.

2. Select cells B1 to B7.
