Understanding How Locking Works in Excel

Fortunately, Excel allows you to lock an entire sheet to prevent any changes or lock specific cells to prevent them from being edited while keeping the rest of the areas open for input.

Here is the golden rule of locking cells in excel: Locking cells has no effect until you protect the worksheet. By default, all cells are set to "Locked." To allow editing in specific areas, you must "Unlock" them before protecting the sheet.

How to Lock Specific Cells or Protect Selected Cells

The following steps will guide you to open (unlock) input cells and then protect cells in excel that shouldn't be touched. To know how to lock a cell in excel properly, please do the following:

1. Select All Cells: Click the arrow in the upper left corner of the worksheet (or press Ctrl + A) to select all cells in the active worksheet.

2. Open Format Cells: Right-click on any selected cell and select Format Cells from the context menu (or press the shortcut Ctrl + 1).

3. Unlock All Cells: In the Format Cells dialog, go to the Protection tab. Uncheck the "Locked" box and click OK. Now, all cells in your sheet are editable.

4. Select Cells to Lock: Highlight only the specific cells and ranges you want to excel protect cells (like headers or data tables). Right-click and select Format Cells again.

5. Lock Selected Cells: Check the Locked option under the Protection tab and click OK. These specific cells are now ready to be protected.

How to Lock Formulas in Excel

3. Click Special... and select Formulas. Click OK. Excel will now highlight only the cells containing formulas.
4. Press Ctrl + 1, go to the Protection tab, and check Locked.

Final Step: Protecting the Worksheet

Your cells are configured, but the lock isn't active yet. You must enable sheet protection.

6. Click Review > Protect Sheet to excel lock cells from editing.

7. Set a Password: Enter a password in the empty box of the Protect Sheet dialog and click OK. Retype the password to confirm.
