Adding Comments to Protected Worksheets

Doug notes that Excel allows you to add comments to cells, but only if the worksheet is unprotected. He wonders if there is a way to allow the addition of comments in protected worksheets.

There are a few ways you can tackle this problem. The first is to simply modify how you protect your worksheet. Starting with an unprotected worksheet, follow these steps:

1. Display the Home tab of the ribbon.
2. In the Cells group, click Format | Protect Sheet. (You could also click the same tool on the Review tab of the ribbon.) Excel displays the Protect Sheet dialog box. (See Figure 1.)

3. Enter a password to be used in protecting the worksheet.
4. Scroll down in the list of permissions and select the Edit Objects check box. (Comments are considered objects in Excel.)
5. Set any other permissions desired.
6. Click OK to dismiss the dialog box. If you provided a password in step 3 you are prompted to reenter it, which you should do.

Any worksheet user can now add comments to cells. Note that this allows them to add comments to any cells in the worksheet, not just to those cells that you've formatted as unlocked. In addition, users can also modify (add, change, or delete) any other objects in the worksheet, such as drawings and charts.

If you want a more granular approach to dealing with comments in protected worksheets, then you'll need to resort to using a macro. The concept is to have the macro prompt the user for the comment text, unlock the worksheet, insert the comment, and then relock the worksheet.

Public Sub InsertComment()
    Dim sPassword As String
    Dim MyComment As String

    sPassword = "123"

    Set commentCell = ActiveCell
    MyComment = InputBox("Enter your comments", "Comments")

    ActiveSheet.Unprotect Password:=sPassword
    Range(commentCell.Address).AddComment
    Range(commentCell.Address).Comment.Text Text:=MyComment
    ActiveSheet.Protect Password:=sPassword
End Sub

Change the value assigned to the sPassword variable; this is required to unlock and relock the worksheet. Since you are storing the password in the macro, you'll also want to make sure that you take steps to protect the macro (put a password on the VBA module) so others cannot see the password. The macro can be assigned to a shortcut key or added to the Quick Access Toolbar.
