相信不少人有过遇到过类似的问题，我也把这个记录一下。
注意：excel打开加密的方式不在本文的介绍范围内。
破解这种保护工作薄的两种方式：
1、利用VB宏代码来破解
注意：如果是高版本的(2013测试不成功)，最好另存为97-2003版本的，否则代码可能无法执行成功。
我这里的环境：office 2013 & win 7
首先另存为97-2003版，然后打开97-2003版的文件。
打开被保护的文件.xls(97-2003)的表,alt+F11，进入VBA编辑器，插入-模块，粘贴这段代码

依次点击：工具-宏
点击运行
破解完成
2、暴力删除保护代码
打开压缩软件(Winrar),找到这个文件，点击查看
将workbook.xml解压出来，用notepad++找这个关键词：workbookProtection
然后删除箭头标记的这一段，保存。
将修改过的文件拖入winrar中，更新workbook.xml这个文件。
然后关闭压缩软件，打开excel，你会发现，没有之前的那些提示了，就可以随意编辑excel了。
