网上有很多这个代码，但很多朋友并不太了解如何运用在此做了一些整理，希望对大家有所帮助！
注：很多时候会因为忘记密码丢失重要EXCEL文件而烦恼，这份代码就能帮你找回，仅仅出之这个初衷，如因为这个代码让你感到不安全，那请加强电脑文件的密保，如用在不当的地方，后果自负！
方法/步骤
-
1、新建一个EXCEL文件“BOOK1”，在工具栏空白位置，任意右击，选择Visual Basic项，弹出Visual Basic工具栏：
-
2、在Visual Basic工具栏中，点击“录制”按钮，弹出“录制新宏”对话框，选择“个人宏工作簿”：
-
3、选择“个人宏工作簿”后按确定，弹出如下“暂停”按钮，点击停止：
-
4、在Visual Basic工具栏中，点击“编辑”按钮：
-
5、点击“编辑”按钮后，弹出如下图的编辑界面：
找到“VBAProject（PERSONAL.XLS）－模块－模块1（也可能是模块N-其他数字）”
双击模块1－将右边代码内容清空
-
6、复制“工作保护密码破解”代码到右边框中，点保存，然后关闭“BOOK1”
-
7、运行需要解密的“EXCEL文件”，在Visual Basic工具栏中，点击“运行”按钮
-
8、点击“运行”按钮后，弹出“宏”对话框，
点击运行“PERSONAL.XLS!工作保护密码破解”这个宏
-
9、运行“PERSONAL.XLS!工作保护密码破解”这个宏后，
如下图示意就可以 解除工作表的密码保护了
-
（这个图，如果工作表中有多组不同密码，
每解开一组，就会提示一次，也就说可能会出现几次）
