今天早上朋友問我怎么破解Excel密碼？
Excel加密雖然不能防止能打開的人通過復制等操作外泄，但至少也是一防較好的防線。移除Excel 2013的密碼保護方法如下：
在彈出的“另存為”對話框中，單擊左下角的“工具”按鈕，選擇“常規選項”：
彈出“常規選項”對話框，可以看到，當然有星號顯示密碼：
Excel文件雖然能打開，能編輯，一些工作簿卻因為有了“保護工作表”
密碼而無法編輯。可以用如下代碼進行解除密碼保護。
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
上述代碼在Excel 2013上也是有效的！這個大家不防一試！
