How to protect your Excel spreadsheet? If you don't want your Excel table to be changed randomly, you need to protect it. This guide explains step-by-step how to restrict editing permissions to some cells and an entire worksheet in Excel, helping you protect important data and prevent unauthorized changes. PHP editor Xiaoxin has compiled detailed steps to allow you to easily implement table protection and ensure data security and integrity.

1. Restrict the editing permissions of some cells

Sometimes, you may only want to allow specific cells to be edited, while protecting other cells from being modified. Then you can do it as follows.

1. Taking the picture below as an example, you need to set the "Quantity" column to be editable, and other areas cannot be edited.

2. Use the shortcut key "Ctrl+A" to select the entire table, then right-click the mouse and select [Format Cells]. After the dialog box pops up, check the [Lock] option in the [Protect] interface, and then click [OK] 】.

3. Return to the table, use the mouse to select the editable area, that is, the "Quantity" area, then right-click the mouse and select [Format Cells]. After the dialog box pops up, remove the [Lock] in the [Protect] interface. "Tick" and click [OK].

4. Click [Protect Sheet] in the [Review] list of the menu tab.

5. After the dialog box pops up, check [Protect worksheet and locked cell contents], then enter the password you want to set in the password field, click [OK] and enter it again, "Restrict editing area" of the Excel table It's set.

6. Reopen the file and try to edit previously unlocked cells and locked cells. You'll find that you can only edit unlocked cells, but not the rest.

2. Restrict the editing permissions of the entire Excel worksheet

If you want to protect the entire worksheet from being modified, we only need to perform the last two steps of "Restricting Partial Editing Permissions":

1. After opening the Excel table, click [Protect Worksheet] in the [Review] list of the menu tab;

2. After the dialog box pops up, enter the password in the password field, click [OK] and enter it again, and it is set.

3. After setting, reopen the file and try to edit any cell in the worksheet, you will find that the entire worksheet cannot be edited unless you enter a password to unprotect it.

3. Cancel editing permissions

How to cancel editing permissions if you no longer need to restrict them in the future?

Whether it is restricting the editing permissions of some cells or restricting the permissions of the entire Excel table, you can cancel it by following the following methods.

After opening the Excel table, click [Revoke Worksheet Protection] in the [Review] list of the menu tab. After the dialog box pops up, enter the originally set password in the password field. After clicking [OK], the editing permission will be cancelled. You can then edit the entire table.

4. Forgot the editing permission password

It should be reminded that the "editing permission" password of Excel must be remembered or saved, because Excel does not have a "forgot password" related option, and you cannot remove the permission without a password. Locked areas cannot be edited.

What should I do if I accidentally forget it? In this case, we need the help of other tools.
