接受的答案在Windows 10上的Excel 2019中无法正常工作。找到了查看锁定宏所需的额外步骤。我正在总结步骤。

Add a .zip to the end of the excel filename and hit enter Once the file has been changed to a ZIP file, open it by double clicking on it Inside you would see a folder called xl like below Inside xl, you'll find a file called vbaProject.bin, copy/paste it on the desktop Go to the online Hexadecimal Editor HexEd.it Search for the following texts DPB=... and change them to DPx=... Save the file and close HexEd.it Copy/Paste the updated file from your desktop inside the ZIP file (you would need to overwrite it) Remove the .zip extension from the end of the filename and add the excel extention again. Open the file in excel - you may receive a couple of error notifications, just click through them.

====在接受的答案=====之外的额外步骤

Open the Visual Basic window (usually ALT+F11 if I remember correctly) and open the VBAProject properties (Tools menu). Click on the Protection tab and change (do not remove at this stage) the password to something short and easy to remember (we'll be removing in next step). Save the workbook and then close and reopen. Open again the Visual Basic window and enter the password you just put in. Redo the previous step but this time you can remove (delete) the password. Save the workbook and you have now removed the password.

ElcomSoft提供高级办公密码破断器和高级办公密码恢复产品，只要文档是在Office 2007或更早版本中创建的，就可以适用于这种情况。

还有另一种更简单的解决方案，不存在尺寸问题。今天我使用了这种方法(在一个2003年的XLS文件上，使用Excel 2007)，并且取得了成功。

备份xls文件 在HEX编辑器中打开文件，并找到DPB=…部分 更改DPB=…string to DPx=… 在Excel中打开xls文件 打开VBA编辑器(ALT + F11) 魔术: Excel发现一个无效的键(DPx)，并询问您是否要继续加载项目(基本上忽略保护) 您将能够覆盖密码，因此将其更改为您可以记住的密码 保存xls文件* 关闭并重新打开文档并使用您的VBA魔法!

*注意:请确保您已将密码更改为新值，否则下次打开电子表格Excel将报告错误(意外错误)，然后当您访问VBA模块列表时，您现在将看到源模块的名称，但在尝试打开表单/代码/等时收到另一个错误。要解决这个问题，请返回VBA项目属性并将密码设置为新值。保存并重新打开Excel文档，您应该可以开始了!

我基于Đức Thanh nguynun的精彩回答，让这种方法适用于64位版本的Excel。我在64位的Windows 7上运行Excel 2010 64位。

Open the file(s) that contain your locked VBA Projects. Create a new xlsm file and store this code in Module1 Option Explicit Private Const PAGE_EXECUTE_READWRITE = &H40 Private Declare PtrSafe Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" _ (Destination As LongPtr, Source As LongPtr, ByVal Length As LongPtr) Private Declare PtrSafe Function VirtualProtect Lib "kernel32" (lpAddress As LongPtr, _ ByVal dwSize As LongPtr, ByVal flNewProtect As LongPtr, lpflOldProtect As LongPtr) As LongPtr Private Declare PtrSafe Function GetModuleHandleA Lib "kernel32" (ByVal lpModuleName As String) As LongPtr Private Declare PtrSafe Function GetProcAddress Lib "kernel32" (ByVal hModule As LongPtr, _ ByVal lpProcName As String) As LongPtr Private Declare PtrSafe Function DialogBoxParam Lib "user32" Alias "DialogBoxParamA" (ByVal hInstance As LongPtr, _ ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, _ ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer Dim HookBytes(0 To 5) As Byte Dim OriginBytes(0 To 5) As Byte Dim pFunc As LongPtr Dim Flag As Boolean Private Function GetPtr(ByVal Value As LongPtr) As LongPtr GetPtr = Value End Function Public Sub RecoverBytes() If Flag Then MoveMemory ByVal pFunc, ByVal VarPtr(OriginBytes(0)), 6 End Sub Public Function Hook() As Boolean Dim TmpBytes(0 To 5) As Byte Dim p As LongPtr Dim OriginProtect As LongPtr Hook = False pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA") If VirtualProtect(ByVal pFunc, 6, PAGE_EXECUTE_READWRITE, OriginProtect) <> 0 Then MoveMemory ByVal VarPtr(TmpBytes(0)), ByVal pFunc, 6 If TmpBytes(0) <> &H68 Then MoveMemory ByVal VarPtr(OriginBytes(0)), ByVal pFunc, 6 p = GetPtr(AddressOf MyDialogBoxParam) HookBytes(0) = &H68 MoveMemory ByVal VarPtr(HookBytes(1)), ByVal VarPtr(p), 4 HookBytes(5) = &HC3 MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0)), 6 Flag = True Hook = True End If End If End Function Private Function MyDialogBoxParam(ByVal hInstance As LongPtr, _ ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, _ ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer If pTemplateName = 4070 Then MyDialogBoxParam = 1 Else RecoverBytes MyDialogBoxParam = DialogBoxParam(hInstance, pTemplateName, _ hWndParent, lpDialogFunc, dwInitParam) Hook End If End Function Paste this code in Module2 and run it Sub unprotected() If Hook Then MsgBox "VBA Project is unprotected!", vbInformation, "*****" End If End Sub

这对我来说很有效，我在这里记录了它，希望它能帮助别人。我还没有完全测试过。请确保在继续此选项之前保存所有打开的文件。

对于Windows 10机器上的Excel 2016 64位，我使用了十六进制编辑器来更改受保护的xla的密码(尚未对任何其他扩展进行测试)。 提示:在执行此操作之前创建备份。

我采取的步骤:

在十六进制编辑器中打开vba(例如XVI) 搜索这个DPB 将DPB更改为其他内容，如DPX 保存它! 重新打开.xla，将出现一条错误消息，继续。 您现在可以通过打开属性并转到password选项卡来更改.xla的密码。

我希望这对你们中的一些人有所帮助!
