您可以尝试这种不需要HEX编辑的直接VBA方法。它将适用于任何文件(*.xls， *.xls， *.xls)。xlsm, *。xlam……)。

它是如何工作的

我会尽我最大的努力解释它是如何工作的-请原谅我的英语。

The VBE will call a system function to create the password dialog box. If user enters the right password and click OK, this function returns 1. If user enters the wrong password or click Cancel, this function returns 0. After the dialog box is closed, the VBE checks the returned value of the system function if this value is 1, the VBE will "think" that the password is right, hence the locked VBA project will be opened. The code below swaps the memory of the original function used to display the password dialog with a user defined function that will always return 1 when being called.

使用代码

请先备份您的文件!

Open the file(s) that contain your locked VBA Projects Create a new xlsm file and store this code in Module1 code credited to Siwtom (nick name), a Vietnamese developer Option Explicit Private Const PAGE_EXECUTE_READWRITE = &H40 Private Declare Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" _ (Destination As Long, Source As Long, ByVal Length As Long) Private Declare Function VirtualProtect Lib "kernel32" (lpAddress As Long, _ ByVal dwSize As Long, ByVal flNewProtect As Long, lpflOldProtect As Long) As Long Private Declare Function GetModuleHandleA Lib "kernel32" (ByVal lpModuleName As String) As Long Private Declare Function GetProcAddress Lib "kernel32" (ByVal hModule As Long, _ ByVal lpProcName As String) As Long Private Declare Function DialogBoxParam Lib "user32" Alias "DialogBoxParamA" (ByVal hInstance As Long, _ ByVal pTemplateName As Long, ByVal hWndParent As Long, _ ByVal lpDialogFunc As Long, ByVal dwInitParam As Long) As Integer Dim HookBytes(0 To 5) As Byte Dim OriginBytes(0 To 5) As Byte Dim pFunc As Long Dim Flag As Boolean Private Function GetPtr(ByVal Value As Long) As Long 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 Long Dim OriginProtect As Long 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 Long, _ ByVal pTemplateName As Long, ByVal hWndParent As Long, _ ByVal lpDialogFunc As Long, ByVal dwInitParam As Long) 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 under the above code in Module1 and run it Sub unprotected() If Hook Then MsgBox "VBA Project is unprotected!", vbInformation, "*****" End If End Sub Come back to your VBA Projects and enjoy.

Colin Pickard has an excellent answer, but there is one 'watch out' with this. There are instances (I haven't figured out the cause yet) where the total length of the "CMG=........GC=...." entry in the file is different from one excel file to the next. In some cases, this entry will be 137 bytes, and in others it will be 143 bytes. The 137 byte length is the odd one, and if this happens when you create your file with the '1234' password, just create another file, and it should jump to the 143 byte length.

如果您尝试将错误的字节数粘贴到文件中，当您尝试用Excel打开该文件时，您将丢失VBA项目。

EDIT

这对Excel 2007/2010文件无效。标准的。xlsx文件格式实际上是一个。zip文件，包含许多子文件夹，其中格式、布局、内容等存储为xml数据。对于未受保护的Excel 2007文件，只需将.xlsx扩展名更改为.zip，然后打开zip文件并查看所有xml数据。这很简单。

但是，当您对Excel 2007文件进行密码保护时，整个.zip (.xlsx)文件实际上是使用RSA加密进行加密的。不再可以将扩展名更改为.zip并浏览文件内容。

你试过在OpenOffice.org中打开它们吗?

前段时间我遇到了类似的问题，发现Excel和Calc不能理解彼此的加密，因此允许直接访问几乎所有内容。

这是一段时间以前，所以如果这不仅仅是我的侥幸，它也可能已经被修补。

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。

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.

从以下站点采取额外步骤 https://confluence.jaytaala.com/display/TKB/Remove+Excel+VBA+password

万一你的街区 没有发生= \ r \ nDPB“XXXX”=“XXXXX”\ r \ nGC =“XXXXXX” 如果您的“已知密码”文件比“未知密码”文件中的现有块短，请用后面的零填充十六进制字符串以达到正确的长度。

e.g.

CMG=“xxxxxx”\r\nDPB=“xxxxx”\r\nGC=“xxxxx”

在未知密码文件中，应设置为

CMG="XXXX00"\r\nDPB="XXXXX000"\r\nGC="XXXXXX0000"保留文件长度。

我在office 2007中也使用过。xla(97/2003格式)文件。
