破解 Excel 工作表保护密码

2019年1月7日 Sunndy 0 Comments

如果表格要修改受保护单元格或图表时,需要“撤消工作表保护”,我们可以用VBA宏代码破解法来破解表格保护密码。本方法适用于 Microsoft Office 97—2003(.xls),高版本工作簿(.xlsx)可以尝试另存为低版本之后再破解。

1、通过菜单“文件 –> 新建 –> 空白工作簿”新建一个新的工作簿来创造新的宏绕过密码保护机制;

2、选择“视图 –> 宏 –> 宏录制”;

3、宏名可以随便填写,然后点击“确定”;

4、这里先什么都不用做,选择“视图 –> 宏 –> 停止录制”;

5、查看刚刚创建的宏,选择“视图 –> 宏 –> 查看宏”;

6、对刚刚新建的宏进行编辑;

7、点击“编辑”打开“Microsoft Visual Basic 编辑器”,把原有的代码删除;

8、将下边的VBA代码复制,替换“Microsoft Visual Basic 编辑器”原有的全部代码,然后不要关闭窗口,将其最小化;

9、这时我们打开需要破解的加密文档,在这个文档选择“视图 –> 宏 –> 查看宏”;

10、刚刚编辑完的宏,已经显示在这里,选择并点击“执行”;

11、执行之后会看到提示,点击“确定”继续执行;

12、运行破解需要等待一定时间,视乎你的机器计算能力,破解之后密码就会被重置并显示出来(这个密码并不是原来的密码,只能在运行了这个宏的文档上使用);

13、整个破解流程完成了,之后记得将其“另存为”。


执行宏之后,如果出现长时间”未响应“

可以尝试将工作簿“另存为” Microsoft Office 97—2003(.xls)并重启计算机再执行。

Microsoft Visual Basic 编辑器提示“编译错误:缺少:标识符”

重启计算机、Excel再尝试粘贴代码可以解决。
