今天早上朋友问我怎么破解Excel密码？
Excel加密虽然不能防止能打开的人通过复制等操作外泄，但至少也是一防较好的防线。移除Excel 2013的密码保护方法如下：
点击“Office”按钮，再选择“另存为”：
在弹出的“另存为”对话框中，单击左下角的“工具”按钮，选择“常规选项”：
弹出“常规选项”对话框，可以看到，当然有星号显示密码：
将这个星号显示的密码清除，再单击“确定”即可：
Excel文件虽然能打开，能编辑，一些工作簿却因为有了“保护工作表”密码而无法编辑。可以用如下代码进行解除密码保护。
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)
Exit Sub
End If
Next: Next: Next: Next: Next: Next
Next: Next: Next: Next: Next: Next
End Sub
上述代码在Excel 2013上也是有效的！这个大家不防一试！
