excel密码忘记了怎么办（office 2007）-excel2007工作表保护,excel怎么取消工作表保护

第一步，先找到一个带有有工作表保护密码的百Excel工作表，然后把后缀名称改为.rar。

第二步，用压缩文件打开度，然后找压缩的对应路径。

第三步，把从压缩文件里面找到的.xml文件，然后拖拽出来，进行修改。

第四步，把保护代码删除来撤消工作知表保护，找到这个.xml文件用记事本道打开，然后搜索【protection】，把从<sheetprotection.........="0"/>的代码，全部删除掉，如图所示。

第五步，然后再把刚刚修改后的.xml文件，选择拖拽到压缩的工作表中替换掉。

第六步，再把文件名称后缀改为.xlsx，打开Excel表格，密码保护就可以取消了。

第七步，撤消保护工内作表后，还可以在【审阅】容选项下对工作表重新进行进行保护和撤消保护工作表操作，如图所示。

如果Excel文件的打开密码忘记了，且密码是7位数以内的数字，可用以下步骤解开：
新开一Excel，同时按Alt和F11，进入VBA界面，点菜单上的插入，模块，在新出来的窗口粘贴一下代码：
Sub crack()
Dim i As Long
Dim FileName As String
Application.ScreenUpdating = False
i = 1
FileName = Application.GetOpenFilename("Excel文件（*.xls & *.xlsx）,*.xls;*.xlsx", , "VBA破解")
FileName = Right(FileName, Len(FileName) - InStrRev(FileName, "\"))
line2:
On Error GoTo line1
Do While True
Workbooks.Open FileName, , , , i
MsgBox "Password is " & i
Exit Sub
Loop
line1:
i = i + 1
Resume line2
Application.ScreenUpdating = True
End Sub然后直接在e79fa5e98193e4b893e5b19e363此界面下按F5运行此宏如果有字母，稍微复杂些，道理是类似的。太长的密码，基本解不开了。若果还有读写密码，且与打开密码一样，将Workbooks.Open FileName, , , , i 改为Workbooks.Open FileName, , , , i, i
是保护工作表密码吗？如果是，可以用宏代码进行破解，方法如下
（1）打开工作表
（2）按“Alt+F11”调出VBA编辑器，选择“插入”—“模块”—把下列7a686964616fe58685e5aeb9335“宏代码”粘贴进去保存，退出VBA编辑器，回到工作表界面

用宏代码破解密码：
以office2007为例说明，（2003也是一样的，只是菜单命令的位置不同）

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7a64e4b893e5b19e366“启用此内容”，“确定”退出；
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，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
