我尝试了上面的一些解决方案，但没有一个适合我(excel 2007 xlsm文件)。然后我找到了另一个解决方案，甚至检索密码，而不仅仅是破解它。

将此代码插入模块，运行它并给它一些时间。它将恢复您的密码的蛮力。

Sub PasswordBreaker()

'Breaks worksheet password protection.

Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim i1 As Integer, i2 As Integer, i3 As Integer
Dim i4 As Integer, i5 As Integer, i6 As Integer
On Error Resume Next
For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126
ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _

If ActiveSheet.ProtectContents = False Then

Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)

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。

保护是Excel中的一个简单的文本比较。 在你最喜欢的调试器中加载Excel (Ollydbg是我选择的工具)，找到进行比较的代码并将其修复为总是返回true，这应该可以让你访问宏。

删除VBA项目密码的一个简单方法是执行以下操作:

将xlsm文件转换为zip 打开VBAProject.bin文件(我更喜欢使用notepad++ (https://notepad-plus-plus.org/downloads/)) 搜索DPB字段 用DPx替换它 保存文件 将zip文件转换为XLSM 打开excel文件 如果出现消息框，请单击“是” 为VBA项目属性设置新密码 关闭并再次打开该文件 输入新密码取消保护

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。
