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

Access、Excel、Powerpoint或Word文档上的VBA项目密码(带有扩展名. accdb . xlsm . xltm . docm . dotm . potm . ppsm的2007、2010、2013或2016版本)可以轻松删除。

这只是将文件名扩展名更改为. zip，解压缩文件，并使用任何基本的十六进制编辑器(如XVI32)来“打破”现有密码的问题，这会“混淆”Office，因此它会在下次打开文件时提示输入新密码。

步骤总结:

rename the file so it has a .ZIP extension. open the ZIP and go to the XL folder. extract vbaProject.bin and open it with a Hex Editor "Search & Replace" to "replace all" changing DPB to DPX. Save changes, place the .bin file back into the zip, return it to it's normal extension and open the file like normal. ALT+F11 to enter the VB Editor and right-click in the Project Explorer to choose VBA Project Properties. On the Protection tab, Set a new password. Click OK, Close the file, Re-open it, hit ALT+F11. Enter the new password that you set.

此时，如果您愿意，您可以完全删除密码。

完整的说明和我制作的“way back when”视频在YouTube上。

令人震惊的是，这种解决方法已经存在多年了，而微软还没有解决这个问题。

这个故事的寓意是什么?

Microsoft Office VBA项目密码不依赖于任何敏感信息的安全。如果安全性很重要，请使用第三方加密软件。

Colin Pickard is mostly correct, but don't confuse the "password to open" protection for the entire file with the VBA password protection, which is completely different from the former and is the same for Office 2003 and 2007 (for Office 2007, rename the file to .zip and look for the vbaProject.bin inside the zip). And that technically the correct way to edit the file is to use a OLE compound document viewer like CFX to open up the correct stream. Of course, if you are just replacing bytes, the plain old binary editor may work.

顺便说一句，如果你想知道这些字段的确切格式，他们现在有文档:

编辑:这是已接受答案的更新版本，应该适用于更多的办公室版本。这很难，但让我们把这个答案说出来吧!

轮到我了，这是建立在kaybee99的优秀答案之上的，它建立在Đức Thanh nguykun的出色答案之上，允许这种方法与32/64位版本的Office一起工作。

概览一下更改的内容，我们避免了push/ret，它仅限于32位地址，并将其替换为mov/jmp reg。

它是如何工作的

Open the file(s) that contain your locked VBA Projects. Create a new file with the same type as the above 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 11) As Byte Dim OriginBytes(0 To 11) 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)), 12 End Sub Public Function Hook() As Boolean Dim TmpBytes(0 To 11) As Byte Dim p As LongPtr, osi As Byte Dim OriginProtect As LongPtr Hook = False #If Win64 Then osi = 1 #Else osi = 0 #End If pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA") If VirtualProtect(ByVal pFunc, 12, PAGE_EXECUTE_READWRITE, OriginProtect) <> 0 Then MoveMemory ByVal VarPtr(TmpBytes(0)), ByVal pFunc, osi+1 If TmpBytes(osi) <> &HB8 Then MoveMemory ByVal VarPtr(OriginBytes(0)), ByVal pFunc, 12 p = GetPtr(AddressOf MyDialogBoxParam) If osi Then HookBytes(0) = &H48 HookBytes(osi) = &HB8 osi = osi + 1 MoveMemory ByVal VarPtr(HookBytes(osi)), ByVal VarPtr(p), 4 * osi HookBytes(osi + 4 * osi) = &HFF HookBytes(osi + 4 * osi + 1) = &HE0 MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0)), 12 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

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。

是的，只要你使用的是。xls格式的电子表格(2003年以前Excel的默认格式)。对于Excel 2007以后，默认是.xlsx，这是一个相当安全的格式，这个方法将不起作用。

正如Treb所说，这是一个简单的比较。一种方法是使用十六进制编辑器(参见Windows的十六进制编辑器)简单地交换文件中的密码条目。循序渐进的例子:

Create a new simple excel file. In the VBA part, set a simple password (say - 1234). Save the file and exit. Then check the file size - see Stewbob's gotcha Open the file you just created with a hex editor. Copy the lines starting with the following keys: CMG=.... DPB=... GC=... FIRST BACKUP the excel file you don't know the VBA password for, then open it with your hex editor, and paste the above copied lines from the dummy file. Save the excel file and exit. Now, open the excel file you need to see the VBA code in. The password for the VBA code will simply be 1234 (as in the example I'm showing here).

如果你需要使用Excel 2007或2010，下面有一些其他的答案可能会有帮助，特别是这些:1、2、3。
