1、Excel 密码保护的解除方法与解除原理 出现这种情况，应该怎么解决呢？经过研究，找到了两种破解 Excel 工作表保护码的方法。一、VBA 宏代码破解法：第一步：打开该文件，先解除默认的“宏禁用”状态，方法是点击工具栏下的“选项”状态按钮，打开“Microsoft Office 安全选项”窗口，选择其中的“启用此内容”，“确定”退出(图 2)；再切换到“视图”选项卡，点击“宏”“录制宏”，出现“录制新宏”窗口，在“宏名”定义一个名称为：PasswordBreaker(图 3)，点击“确定”退出；第二步：再点击“宏”“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“编辑”，
2、打开“Microsoft Visual Basic”编辑器，用如下内容替换右侧窗口中的所有代码：Sub PasswordBreaker()Dim i As Integer, j As Integer, k As IntegerDim l As Integer, m As Integer, n As IntegerDim i1 As Integer, i2 As Integer, i3 As IntegerDim i4 As Integer, i5 As Integer, i6 As IntegerOn Error Resume NextFor i = 65 To 66: For j = 65
3、To 66: For k = 65 To 66For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _Chr(i4) & Chr(i
4、5) & Chr(i6) & Chr(n)If ActiveSheet.ProtectContents = False ThenMsgBox “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).SelectRange(“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 SubEnd IfNext: Next: Next: Next: Next: NextNext: Next: Next: Next: Next: NextEnd Sub第三步：再点击“宏”“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“执行”，密码就现形了(图 4)。第四步：切换“审阅”选项卡，点击“撤消工作表保护”，然后输入密码即可解除锁定。
