二、如何破解excel文件密码
我就用我自己的加密的excel文件叫大家怎么破解清除excel密码，首先打开有自己加密的excel文档，如下图：
excel2010和以前的版本有所不同，功能更人性化，更智能化。首先我们要做的是，加载宏文件，excel为宏设置默认是关闭的，我们要启用宏，就必须开启宏；“文件”下的子菜单”选项“
如下图所示：
点击“选项”选择子菜单下“信任中心”“宏设置”在宏设置下。选择“启用所以宏”然后点击“确定”
如下图所示：
点击“视图”在右下面我们会看“宏”打开宏，如下图所示：
现在我们就开始录制新宏，宏名：随便填，我这么久填密码，保存在：选择当前工作薄，说明可以不填。
如下图所示：
我们在宏工作薄中，把一下宏程序写进去。
