Limiting Who Can Delete Data

Jim has a workbook that is used by multiple people in his company. He wonders if there is a way to allow everyone to add data to a group of cells, yet restrict who can delete the data from the cells. He has a group of about 50 that he wants to be able to add data, but he wants to give the delete capability to just 2 individuals.

There are any number of macro-based solutions you can try. Essentially, you need a macro to detect when information has been deleted and then check to see if the person deleting the information has permission to do so. The following is just one possible approach to the issue:

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim sPassCheck As String
    Dim sTemp As String
    Dim sPassword As String

    sPassword = "Password"
    sTemp = "You must enter the password to delete data"

    If Target.Cells(1, 1).Value = "" Then
        sPassCheck = InputBox(sTemp, "Delete check!")
        Application.EnableEvents = False
        If sPassCheck <> sPassword Then Application.Undo
    End If

    Application.EnableEvents = True
End Sub

The macro, which is actually an event handler triggered whenever something in the worksheet is changed, checks to see if the information in the top-left corner of the range was deleted. If so, then the user is asked for a password. If the person doesn't have the password, then the Undo method is invoked to "undo" the person's deletion. (You'll want to change the password, assigned to the sPassword variable) to the actual password you want people to use.)

As I said, this macro is just one possible approach. You'll want to think through how your worksheet may be used and then craft a macro to reflect that usage. For instance, you might want to check the Application.UserName property and, if it isn't a specific user, disallow the changes.

Another option is to use an Excel add-in that can take care of the security issues for you. Some subscribers suggest using Add-In A-Tools. You can find more information about this add-in here:

Add-In A-Tools, among other things, apparently allows you to apply various security features to Excel data that resides on a network. (Chances are good that Jim is sharing his workbook on a network, as it is used by many people in his company.)
