如何重置Excel工作表保护密码

1、袄嬖艽蛞录制宏由于加密文档无法新建宏，所以需要先录制一个宏，然后在对现有的宏进行编辑。打开加密文档——开发工具——录制宏，进行录制，然后停止。如图：

2、打开备用宏打开开发工具——宏——编辑。如图：

3、替换代码将备用宏里面的代码全部清空，然后将一下代码复制到编辑区内：Public Sub 工作表保护密码破译()Const DBLSPACE As String = 即枢潋雳vbNewLine & vbNewLineConst AUTHORS As String = DBLSPACE & vbNewLine & _"作者:D兰花开S "Const HEADER As String = "工作表保护密码破译"Const VERSION As String = DBLSPACE & "版本 Version 1.1.1"Const REPBACK As String = DBLSPACE & ""Const ZHENGLI As String = DBLSPACE & " "Const ALLCLEAR As String = DBLSPACE & "该工作簿中的工作表密码保护已全部解除!!" & DBLSPACE & "请记得另保存" _& DBLSPACE & "注意：不要用在不当地方，要尊重他人的劳动成果！"Const MSGNOPWORDS1 As String = "该文件工作表中没有加密"Const MSGNOPWORDS2 As String = "该文件工作表中没有加密2"Const MSGTAKETIME As String = "解密需花费一定时间,请耐心等候!" & DBLSPACE & "按确定开始破译!"Const MSGPWORDFOUND1 As String = "密码重新组合为:" & DBLSPACE & "$$" & DBLSPACE & _"如果该文件工作表有不同密码,将搜索下一组密码并修改清除"Const MSGPWORDFOUND2 As String = "密码重新组合为:" & DBLSPACE & "$$" & DBLSPACE & _"如果该文件工作表有不同密码,将搜索下一组密码并解除"Const MSGONLYONE As String = "确保为唯一的?"Dim w1 As Worksheet, w2 As WorksheetDim i As Integer, j As Integer, k As Integer, l As IntegerDim m As Integer, n As Integer, i1 As Integer, i2 As IntegerDim i3 As Integer, i4 As Integer, i5 As Integer, i6 As IntegerDim PWord1 As StringDim ShTag As Boolean, WinTag As BooleanApplication.ScreenUpdating = FalseWith ActiveWorkbookWinTag = .ProtectStructure Or .ProtectWindowsEnd WithShTag = FalseFor Each w1 In WorksheetsShTag = ShTag Or w1.ProtectContentsNext w1If Not ShTag And Not WinTag ThenMsgBox MSGNOPWORDS1, vbInformation, HEADERExit SubEnd IfMsgBox MSGTAKETIME, vbInformation, HEADERIf Not WinTag ThenElseOn Error Resume NextDo 'dummy do loopFor i = 65 To 66: For j = 65 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 126With ActiveWorkbook.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 .ProtectStructure = False And _.ProtectWindows = False ThenPWord1 = Chr(i) & Chr(j) & Chr(k) & Chr(l) & _Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)MsgBox Application.Substitute(MSGPWORDFOUND1, _"$$", PWord1), vbInformation, HEADERExit Do 'Bypass all for...nextsEnd IfEnd WithNext: Next: Next: Next: Next: NextNext: Next: Next: Next: Next: NextLoop Until TrueOn Error GoTo 0End IfIf WinTag And Not ShTag ThenMsgBox MSGONLYONE, vbInformation, HEADERExit SubEnd IfOn Error Resume NextFor Each w1 In Worksheets'Attempt clearance with PWord1w1.Unprotect PWord1Next w1On Error GoTo 0ShTag = FalseFor Each w1 In Worksheets'Checks for all clear ShTag triggered to 1 if not.ShTag = ShTag Or w1.ProtectContentsNext w1If ShTag ThenFor Each w1 In WorksheetsWith w1If .ProtectContents ThenOn Error Resume NextDo 'Dummy do loopFor i = 65 To 66: For j = 65 To 66: For k = 65 To 66For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126.Unprotect Chr(i) & Chr(j) & Chr(k) & _Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)If Not .ProtectContents ThenPWord1 = Chr(i) & Chr(j) & Chr(k) & Chr(l) & _Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)MsgBox Application.Substitute(MSGPWORDFOUND2, _"$$", PWord1), vbInformation, HEADER'leverage finding Pword by trying on other sheetsFor Each w2 In Worksheetsw2.Unprotect PWord1Next w2Exit Do 'Bypass all for...nextsEnd IfNext: Next: Next: Next: Next: NextNext: Next: Next: Next: Next: NextLoop Until TrueOn Error GoTo 0End IfEnd WithNext w1End IfMsgBox ALLCLEAR & AUTHORS & VERSION & REPBACK & ZHENGLI, vbInformation, HEADEREnd Sub如图：

4、运行保存宏，然后关闭VBA窗口，返回到Excel中，运行宏。如图：

5、开始密码破译点击确定，开始破译并重置保护密码。如图：点击两次确定。

6、编辑文档破译之后，你会看到Excel单元格可以编辑而且相关隐藏的公式等都能显示出来。如图：
