撤銷Excel工作表保護密碼(考勤機報表)

用宏代bai碼破解密碼：
以office2007為例說明，（2003也是一樣的，只是菜單命令的位置不同）

第一步：打開該文件，先解除默認的“宏禁用”狀態，方法是點擊工具欄下的“選項”狀態按鈕，打開“Microsoft Office安全選項”窗口，選擇其中的“啟用此內容”，“確定”退出；
再切換到“視圖”選項卡，點擊“宏”→“錄制宏”，出現“錄制新宏”窗口，在“宏名”定義一個名稱為：PassWordBreaker，點擊“確定”退出；

第二步：再點擊“宏”→“查看宏”，選擇“宏名”下的“PasswordBreaker”並點擊“編輯”，打開“Microsoft Visual Basic”編輯器，用如下內容替換右側窗口中的所有代碼：

Sub PasswordBreaker()
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)
ActiveWorkbook.Sheets(1).Select
Range("a1").FormulaR1C1 = 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

　　

第三步：再點擊“宏”→“查看宏”，選擇“宏名”下的“PasswordBreaker”並點擊“執行”，密碼就現形了。
