破解EXCEL密码最靠谱的办法-excel加密

EXCEL是我们工作中很得力的助手，尤其是一些函数公式大大的方便我我们的一些数据统计、计算等等。看一些高手做的一些带函数公式的EXCEL表格也可以帮助我们学习EXCEL的知识，可是有些高手做的表格都加密了，根本看不到是怎么计算的。所以我们很想把密码去掉，下面我就来分享一下破解过程。

1. 打开需要破解密码的EXCEL表格。

2. 点击工具-宏-录制新宏。默认的宏名称为Macrol，点击确定。

3. 点击停止按钮。

4. 依次点击菜单栏上的工具-宏，选择刚刚录制的宏，默认的宏名称为Macrol。点击右侧的编辑按钮。

5. 清空编辑框内的所有内容。

6. 复制以下代码到编辑框内：
   

   Option Explicit

   ' probably originator of base code algorithm modified for coverage
   ' of workbook structure / windows passwords and for multiple passwords

7. 点击工具栏内的运行按钮。选运行子过程/用户窗体。

8. 跳出对话框后点击确定，稍后再次跳出对话框后再次点击确定。

9. 稍等一会儿，跳出密码。注意：这个密码并不是原作者设定的密码，但是确实可以用，可原密码无异。

10. 点击确定，然后会自动备份一个不加密的文件出来。

11. 破解完成。
