Unless you do it manually, one content control at a time, you'll need a macro to delete the content controls. For example:
Code:
Sub Demo()
Application.ScreenUpdating = False
Dim i As Long
With ActiveDocument
For i = .ContentControls.Count To 1 Step -1
With .ContentControls(i)
.LockContentControl = False
.Delete False
End With
Next
End With
Application.ScreenUpdating = True
End Sub
or:
Code:
Sub Demo()
Application.ScreenUpdating = False
With ActiveDocument
Do While .ContentControls.Count > 0
With .ContentControls(1)
.LockContentControl = False
.Delete False
End With
Loop
End With
Application.ScreenUpdating = True
End Sub
Do note that macros can't be stored in docx files, so you'd need to add it to the relevant document's template.
