How to Lock Certain Cells in Excel

Microsoft Excel is an exceptional tool for data management and analysis, utilized by millions of people globally. Most basic data entry spreadsheets have at least a few different calculations, and from time to time, you’ll need to restrict certain cells from being edited or modified. This safeguard is especially critical when the worksheet is accessible to others or even more when the data in the cells contains important and confidential information. Excel makes it simple to protect specific cells while still allowing others to be modified, and in this comprehensive guide, we’ll show you how to lock certain cells in Excel.

Determine which cells you want to lock

Before you start, you need to identify the cells you want to lock, for example, cells containing sensitive information that should not be changed. You can determine beforehand which cells to lock or select the cells while following the steps below.

Select the cells you want to lock

Once you have identified the cells you want to protect, select them by clicking and dragging over them. If the cells you want to lock are not next to each other, hold down the Ctrl key and click on the cells you would like to protect.

Lock the selected cells

To lock the selected cells, follow these simple steps:

Step 1:

Right-click on the selected cells and select “Format Cells” from the menu that appears.

Step 2:

Click on the “Protection” tab in the format cells dialog box that appears.

Step 3:

Check the box next to “Locked” to lock the selected cells and prevent anyone from editing them.

Step 4:

Click “OK” to save your changes, and then select the cells that you want the users to modify. Remember to uncheck the Locked option on these cells.

Protect the worksheet

After you have locked the necessary cells, it is essential to protect the worksheet to prevent changes to cells that aren’t locked. To do this, follow these steps:

Step 1:

On the “Review” tab, click “Protect Sheet.”

Step 2:

In the “Protect Sheet” dialog box, check the boxes to allow certain actions that can still be performed on the worksheet while it’s protected, such as selecting unlocked cells, formatting, and sorting. Enter a password if you want to make it more secure.

Step 3:

Click “OK” to protect the sheet, and your locked cells will now be safeguarded from editing.

With these simple steps, you can quickly lock certain cells in Excel and secure your sensitive data without exposing it to other viewers. Follow this guide, protect your worksheet, and keep your valuable information safe.

Unlocking Cells When Necessary

If for any reason you need to modify the locked cells (e.g., to update the information), you can always unlock them temporarily. Remember, you’ll need to unprotect the worksheet first before you can unlock the cells.

Step 1:

Right-click on the cell you want to modify and click “Format Cells.”

Step 2:

Click on the “Protection” tab in the format cells dialog box.

Step 3:

Uncheck the box next to “Locked” to unlock the selected cells.

Step 4:

Click “OK” to apply the changes and update the cell. Remember to re-lock the cell by following the steps above after you’ve modified the cell.

Protecting a Workbook with Password

To secure your workbook by adding a password protection option, follow these steps:

Step 1:

Click File > Save As.

Step 2:

Give a name to your file and then click on the Tools button located next to the Save button, select General Options.

Step 3:

In the General Options dialog box under “Password to open,” enter a password.

Step 4:

Click “OK” and confirm the password in the next dialog box.

Step 5:

Click “Save,” and your workbook is now password-protected. When you try to open the workbook, you will need to enter the password you just set up.

Now, you know how to lock certain cells in Excel and protect your important and sensitive data. By making use of Excel’s security features, you can safeguard your data from unauthorized editing by others.
