6、关闭编辑窗口；
7、依次点击菜单栏上的工具---宏-----宏,选AllInternalPasswords,运行,确定两次；
等一会,就会出现以下对话框：这就是Excel密码对应的原始密码(此密码和原先设置的密码都能打开此文档。如果是别人的文档，你又想恢复密码设置，就可以用此密码进行保护，他就能用他设置的密码打开，你可以试试，很有趣的。字母一定要大写)：
Q2：excel表格中忘了撤销工作表保护密码怎么办
excel表格中忘了撤销工作表保护密码怎么办 网上下个解密工具！ 找个破解软件破解即可，很多的，自己搜索一下，不保密的话发给我给你破解，需要HI
Q3：工作表被保护了，没密码，怎么破解？
小编刚刚在头条上分享过的文章，可以去搜索极客坊看一看。文件密码忘记，要怎么样找回密码，推荐这3个工具。
Advanced Office Password Recovery
该款工具是专门针对Office文件，可对我们常见的word、excel、PPT等办公文件进行密码找回。启动软件，点击：‘打开“，打开文件，首先要对软件进行设置，选项选择密码位数或密码是字母还是字符，越复杂的组合所花的时间越久，如果记得大概，可以进行模糊设定。以便缩短时间。
Advanced PDF Password Recovery
该工具是专门针对PDF文件，PDF文件分为打开权限和打印权限密码，此工具只能找回打开权限，打印权限只能通过截图的方式曲线使用。启动软件，打开文件，恢复模式选择“bao力 破 解”，设置筛选条件，设置密码长度，设置字符为0→9、a-z（一般尝试小写字母）即可，点击“开始”即可进行。
Advanced Archive Password Recover
针对压缩文件，RAR、ZIP.、ACE和ARJ的密码找回。
以上3款软件可以对我们常用文件进行密码找回，所使用的方式都是穷举法，所以如果密码复杂，花费的时间就会很久，如果自己记得一点，比如是否纯数字，是否纯字母，是否数字＋字母等等，在开始进行破解时能正确设定将大大缩短时间。
Q4：撤销工作表保护密码考勤机报表被保护怎么撤销
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“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
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。

Q5：EXCEL工作表保护密码忘记了，如何撤消工作表保护？
第一步，先找到一个带有有工作表保护密码的Excel工作表，然后把后缀名称改为.rar。
第二步，用压缩文件打开，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表保护，找到这个.xml文件用记事本打开，然后搜索【protection】，把从
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，撤消保护工作表后，还可以在【审阅】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。
