神技 破解EXCEL工作表保护密码 http://www.mr-wu.cn/crack-excel-workbook-protection/
我们可以通过新建工作本，来创建一个新的工作本来创造新的宏而绕过密码保护机制。
在打开的PDN_Tool_v1_1_1.xls工作本里，通过菜单“文件–>新建工作本“，创建一个新的空白工作本。
在新建的工作本里，通过菜单”工具–>宏–>录制新宏…“来创建一个新的宏。
但我们这里先什么都不用做，直接菜单”工具–>宏–>停止录制“来创建一个空白的宏，我们会对这个新的宏进行编辑工作。
通过菜单”工具–>宏–>宏…“，来打开宏选择窗口，我们会在宏窗口的选择列表里看到我们刚才新建的那个宏”hh”。
选择宏“hh”，然后点击“编辑”按钮。
在弹出的“Visual Basic 编辑器”窗口右边，删除原有的代码，将下边的VBA代码粘贴减去，然后关闭“Visual Basic 编辑器”窗口。
