使用VBA代碼在Excel中恢復丟失的工作表保護密碼

以下VBA代碼可以幫助您快速取消工作表中的原始密碼。

1。 打開您以前受保護的工作表。

2。 按住 ALT + F11 鍵,然後打開 Microsoft Visual Basic for Applications窗口.

3。 點擊 插入 > 模塊,然後將以下代碼粘貼到 模塊窗口.

VBA代碼:恢復丟失的工作表保護密碼

Sub PasswordRecovery()
Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim i1 As Integer, i2 As Integer, i3 As Integer
Dim i4 As Integer, i5 As Integer, i6 As Integer
On Error Resume Next
For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126
ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
If ActiveSheet.ProtectContents = False Then
MsgBox "One usable password is " & Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
Exit Sub
End If
Next: Next: Next: Next: Next: Next
Next: Next: Next: Next: Next: Next
End Sub

4。 然後點擊 F5 鍵運行此代碼,然後會彈出一個提示框,單擊 OK 將其關閉,您的受保護工作表密碼將立即被取消。

筆記:

1.使用此代碼,您一次只能恢復一個工作表保護密碼,如果有多個受保護的工作表,則需要一個一個地應用此代碼。

This does not appear to work. It only generates passwords with As, Bs and something else at the end. What am I missing?
