1、打开您需要撤销保护密码的Excel文件；

2、依次点击菜单栏上的工具---宏----录制新宏，输入宏名字如:ab；

3、停止录制(这样得到一个空宏)；

4、依次点击菜单栏上的工具---宏----宏,选ab,点编辑按钮；

5、删除窗口中的所有字符(只有几个),替换为以下内容；

Public Sub 工作表保护密码()
Const DBLSPACE As
String = vbNewLine & vbNewLine
Const AUTHORS As String = DBLSPACE &
vbNewLine & _
"作者:eric"
Const HEADER As String = "工作表保护密码"
Const
VERSION As String = DBLSPACE & "版本 Version 1.1.1"
Const REPBACK As String
= DBLSPACE & ""
Const ZHENGLI As String = DBLSPACE &
"
eric"
Const ALLCLEAR As String = DBLSPACE & "该工作簿中的工作表密码保护已全部解除。" &
DBLSPACE & "请记得重新设置密码" _
& DBLSPACE & "注意：此方法仅用于遗忘密码使用。"
Const
MSGNOPWORDS1 As String = "该文件工作表中没有加密"
Const MSGNOPWORDS2 As String =
"该文件工作表中没有加密2"
Const MSGTAKETIME As String = "请耐心等候!" & DBLSPACE &
"按确定开始回复"
Const MSGPWORDFOUND1 As String = "密码重新组合为:" & DBLSPACE &
"$$" & DBLSPACE & _
"如果该文件工作表有不同密码,将搜索下一组密码并修改清除"
Const
MSGPWORDFOUND2 As String = "密码重新组合为:" & DBLSPACE & "$$" & DBLSPACE
& _
"如果该文件工作表有不同密码,将搜索下一组密码并解除"
Const MSGONLYONE As String =
"确保为唯一的?"

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，等候一两分钟,会出现以下对话框：

这是Excel密码对应的原始密码(此密码和之前设置的密码均能打开此文档。

2007--审阅--保护工作表，点进去就可以取消。但如果保护密码为全保护而又忘记了密码，可能就需要专门的破解软件了。

2007--审阅--保护工作表，点进去就可以取消，2003的也差不多
