提问然后呢

回答2、用压缩文件打开忘记密码的Excel文件，然后按以下步骤进行操作：xl——worksheets——sheet1.xml（这里是将sheet1工作表设置了保护密码，可根据实际情况选择相应文件名

3、从压缩文件里面找到sheet1.xml文件，然后拖拽至一个方便找到的位置（因为我们要对其要进行修改） 。然后将sheet1.xml文件右击选择用记事本打开方式打开。

4、然后搜索，“protection”，把从这一段代码，全部删除掉。

提问好难呀

回答、然后再把修改后的sheet1.xml文件，选择拖拽到压缩的工作薄中，选择替换掉即可，点击确定

6、最后一步，和第一步相反，把文件名称后缀，由“演示表格.rar”重新更改“演示表格.xlsx”。最后打开Excel表格，你会惊喜地发现是不是保护密码都取消了吧。

提问为什么更换后缀后提示错误，说压缩文件格式未知

回答有解压软件吗

提问有的

回答更改后缀只适用于.xlsx

如果Excel文件的打开密码忘记了，且密码是6位数以内的数字，可用以下步骤解开（关掉所有程序，为了速度）：
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
i = 0
FileName = Application.GetOpenFilename("Excel文件（*.xls & *.xlsx）,*.xls;*.xlsx", , "VBA破解")
FileName = Right(FileName, Len(FileName) - InStrRev(FileName, "\"))
Application.ScreenUpdating = False
line2: On Error GoTo line1
Workbooks.Open FileName, , True, , i
MsgBox "Password is " & i
Exit Sub
line1: i = i + 1
Resume line2
Application.ScreenUpdating = True
End Sub

然后在此界面直接按F5运行此宏，

用专业的Excel密码破解工具，这样可以极大的保证密码找回成功率并保证安全，这里以使用Advanced Office Password Recovery找回Excel密码为例介绍如何找回密码。
