How to lock cells in Excel

1. Select the cells you want to protect.
2. Right-click and select "Format Cells".
3. In the "Format Cells" dialog box, go to the "Protection" tab.
4. Select the "Locked" option to prevent changes to the selected cells.
5. Enter a password in the "Password" box and confirm it in the "Confirm Password" box.
6. Click "OK" to confirm the changes.

Now, when someone tries to edit the protected cells, they will be prompted for the password you set. Without the correct password, no changes can be made to the protected cells.

Note that if you want to protect the entire worksheet instead of individual cells, you will need to select the entire sheet before following the above steps.

This method is useful if you need to share your worksheet with others but want to keep some information confidential or sensitive. For example, you may want to protect formulas or financial data so that only those with the password can access it.

How to unlock protected cells

If you need to edit a protected cell in an Excel worksheet, you can follow these steps to unlock it:

• Select the cell or cells you want to unlock.
• Right-click on the selection and choose "Format Cells".
• In the "Format Cells" window, go to the "Protection" tab.
• Clear the "Locked" checkbox and click OK.

Now the selected cells have been unlocked and you can edit the data as desired. However, to safeguard your data, it is important to restore cell protection after making any necessary changes.

To restore cell protection, follow these steps:

• Select the cells you want to protect again.
• Right-click on the selection and choose "Format Cells".
• In the "Format Cells" window, go to the "Protection" tab.
• Select the "Locked" checkbox and click OK.

This way, your changes will be saved but your cells will still be protected from accidental errors or unauthorized changes.

Remember that if the worksheet is password-protected, you will need to enter the password to unlock or protect cells.
