Password-Protect and Unprotect All Excel Worksheets

There is no standard feature in Excel that will enable you to protect and unprotect all worksheets in one go; however, some simple code can make it happen.

Excel provides protection that you can add to an Excel worksheet by selecting Review → Changes → Protect Sheet (pre-2007, Tools → Protection → Protect Sheet). You can also supply a password so that another user cannot unprotect the worksheet and gain access unless he knows the password.

Sometimes, though, you want to password-protect and unprotect all worksheets in a workbook in one step, because protecting and unprotecting each worksheet individually is a huge nuisance. Here is how you can simplify this task.

1. Open the workbook to which you want to apply the code.
   Alternatively, select Windows → View → Unhide to unhide your Personal.xls file and make it available to any workbook. If this option is grayed out, it means you do not have a Personal.xls file yet. You can create one easily by recording a dummy macro:
   1. Select Developer → Code → Record Macro (pre-2007, Tools → Macro → Record New Macro).
   2. Choose Personal Macro Workbook from the Store Macro In: box.
   3. Click OK, select any cell, and stop recording. Excel will create your Personal.xls file automatically.
2. Next, press Alt/Option-F11 and select Insert → UserForm. This should display the Control toolbox. If it doesn't, select View → Toolbox.
3. From the toolbox, select a TextBox (indicated as ab|). Click onto the UserForm to add the TextBox to the UserForm. Position it in the top left of your form and size it to your preference.
4. Ensure that the textbox is still selected and then select View → Properties (F4). From the Properties window of the textbox, scroll down until you see PasswordChar, and in the white box on the right, enter an asterisk (*).
5. From the toolbox, select a CommandButton and then click the UserForm and position it in the top right of your form.
6. With the CommandButton still selected, select View → Properties (F4). From the Properties window of the CommandButton, scroll down until you see Caption, and in the white box on the right, enter the caption OK. If you are using Excel 97, also scroll down until you see TakeFocusOn Click, and set this to False.
7. Now select the UserForm and, from its Properties window, find Caption and change it to Protect/Unprotect all sheets.
8. Select View → Code (F7) and enter the following code exactly as shown:

   Private Sub CommandButton1_Click( )
   Dim wSheet As Worksheet
    For Each wSheet In Worksheets
    If wSheet.ProtectContents = True Then
    wSheet.Unprotect Password:=TextBox1.Text
    Else
    wSheet.Protect Password:=TextBox1.Text
    End If
    Next wSheet
    Unload me
   End Sub
   

   The code loops through all worksheets in the active workbook. If one is protected, it unprotects it using the password entered into the text box. If the worksheet is already unprotected, it protects it using the password entered into the text box.
9. Nowselect Insert → Module and enter this code, which is used to launch the UserForm:

   Sub ShowPass( )
    UserForm1.Show
   End Sub
   

10. Close the window to get back to Excel, then save your workbook.
11. Press Alt/Option-F8, select ShowPass, and then click Options and assign a shortcut key. This will unprotect all worksheets that are protected and protect all worksheets that are unprotected.
12. Remember to save your workbook.

As this macro does not ask you to confirm your password, you should be very sure of what you type. Otherwise, you may find that typos lock you out of your spreadsheets.

If you're protecting the contents only from yourself, the following macro lets you perform the same tasks with a blank password instead:

Option Explicit

Sub Protect_Unprotect( )
Dim wSheet As Worksheet

For Each wSheet In Worksheets
 With wSheet
 If .ProtectContents = True Then
 .Unprotect Password:=""
 Else
 .Protect Password:=""
 End If
 End With
Next wSheet

End Sub

Although it's not very secure, it's definitely convenient.
