1、打开Excel文件，新建一个Excel工作表。
2、在这个工作表的名称上单击右键，执行“查看代码”功能。
3、在弹出的窗口中输入以下代码，保存关闭这个窗口。
Public Sub 工作表保护密码破解() Const DBLSPACE As String = vbNewLine & vbNewLine Const AUTHORS As String = DBLSPACE & vbNewLine & _ "作者:McCormick JE McGimpsey " Const HEADER As String = "工作表保护密码破解" Const VERSION As String = DBLSPACE & "版本 Version 1.1.1" Const REPBACK As String = DBLSPACE & "" Const ZHENGLI As String = DBLSPACE & " hfhzi3—戊冥 整理" Const ALLCLEAR As String = DBLSPACE & "该工作簿中的工作表密码保护已全部解除!!" & DBLSPACE & "请记得另保存" _ & DBLSPACE & "注意：不要用在不当地方，要尊重他人的劳动成果！" 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 = "解密需花费一定时间,请耐心等候!" & DBLSPACE & "按确定开始破解!"

4、在原来的Excel文件中，执行“工具--宏--宏”的功能，执行“工作表保护密码破解”这个宏。
等待几分钟，密码就破解成功了。
