破解宏密码步骤5：按F5执行代码，输入密码长度。如果不知道密码的长度，就猜，第一次输1，第二次输2.。。依次试。
破解宏密码步骤6：输入密码长度后，点击确定。并在2s内将鼠标的焦点点在最开始要破解文件的密码输入框里边。接下来的工作就是“静候佳音”了。
破解宏密码步骤7：没有破解不开的密码。主要的是你有时间就好!1位密码破解最长时间：62/(1/0.005)=0.31秒;2位数密码破解最长时间：62*62/(1/0.005)=19.22秒。。。依次类推：N位数密码破解时间：(62)的N次方/(1/0.005)秒的时间。就看您的耐性了!破解完成之后就会自动进去VBA代码模块。
破解宏密码步骤8：接下来就是修改别人的密码了!进去果断点击VBA工程属性，改密码。
二、如何破解excel密码保护
Excel弹出“您试图更改的单元格或图表受保护，因而是只读的。若要修改受保护单元格或图表，请先使用‘撤消工作表保护’命令(在‘审阅’选项卡的‘更改’组中)来取消保护。可能会提示您输入密码。”窗口，如图1.
出现这种情况，应该怎么解决呢？经过研究，找到了两种破解Excel工作表保护码的方法。
一、VBA宏代码破解法：
第一步：打开该文件，先解除默认的“宏禁用”状态，方法是点击工具栏下的“选项”状态按钮，打开“Microsoft Office安全选项”窗口，选择其中的“启用此内容”，“确定”退出(图2)；
再切换到“视图”选项卡，点击“宏”→“录制宏”，出现“录制新宏”窗口，在“宏名”定义一个名称为：PassWordBreaker(图3)，点击“确定”退出；
第二步：再点击“宏”→“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“编辑”，打开“Microsoft Visual Basic”编辑器，用如下内容替换右侧窗口中的所有代码：
Sub PasswordBreaker()
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) & _
Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
If ActiveSheet.ProtectContents = False Then
MsgBox "One usable password is " & Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
ActiveWorkbook.Sheets(1).Select
Range("a1").FormulaR1C1 = Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
Exit Sub
End If
Next: Next: Next: Next: Next: Next
Next: Next: Next: Next: Next: Next
End Sub
第三步：再点击“宏”→“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“执行”，密码就现形了(图4)。
第四步：切换“审阅”选项卡，点击“撤消工作表保护”，然后输入密码即可解除锁定。
二、软件破解法
有许多专门为破解Excel各种密码而制作的软件，Excel Key与Advanced Office Password Recovery就是其中的佼佼者。它们的使用方法简单且破解速度极快。
1. Excel Key
下载(下载地址：http://www.mydown.com/soft/183/183131.html)安装完后运行软件，点击工具栏“Recovery”按钮，找到要破解的文件，软件马上就可以解出密码了(图5)。
2. Advanced Office Password Recovery
下载(下载地址：http://www.mydown.com/soft/utilitie/security/268/410768.shtml)安装完后运行软件，点击工具栏“Open File”按钮，打开要破解的Excel文件，马上就可以看到解出的密码了(图6)。
可以看出，用以上方法读出的密码完全不同，但它们确实均可以解除该工作表的密码保护，这实在是个有趣的问题。
在网上查找了许久，终于找到比较圆满的解释答案：
当Excel工作表采用密码保护时，就会生成一个16位(双字节)长hash值。当输入密码进行验证时，真正进行比较的就是这个hash值。事实上，有很多不同的密码都可以生成同样的hash值。
大家可以试试：
当你用“test”(不含双引号)作为Excel工作表保护密码，你同样可以用“zzyw”(同样不含双引号)这个密码进行解锁。怎么样，神奇吧?
