破解Excel保护工作表密码
Excel的工作表保护可以保护工作表内容不被修改,只能查看,也可以使工作表内的公式被隐藏,只显示结果。
以下二个方法可以移除Excel工作表的保护密码,并不能查看到原密码。
方法一:
1、打开需要破解密码的Excel文件。
2、按Alt+F11快捷键打开VBA窗口。
3、单击“插入”菜单下的“模块”。
4、将以下代码复制到模块窗口中。

5、按F5键,运行该宏命令。
6、击击二次确定后,等一会就可以移除Excel保护密码了。
方法二:
注:此方法适合Excel 2007格式
1、将需要破解密码的Excel文件的扩展名改为.zip。
2、打开这个.zip压缩包,编辑\xl\worksheets\sheet1.xml,(sheet1.xml是需要破解密码的工作表名)找到以下代码并删除,保存后替换压缩包中的原文件。
3、将Excel文件的扩展名还原为.xlsx。
