如何批量处理excel中的某一列md5加密

背景：在用excel作为数据存储的时候，发现有部分需求需要对手机号进行md5加密

使用VB编写有关md5加密的宏

如何引用：

1.打开excel后，点击右上角“文件”--“选项”，打开excel选项，然后点击“自定义功能区”，勾选“开发工具”，然后确定

2.excel工具栏中新增一列“开发工具”，如图

3.点击“excel加载项”，点击“浏览”，添加之前保存好的宏路径（宏的后缀名为.xla），然后点击“确定”按钮

6.这个时候会弹出下图对话框，关掉然后重新打开excel即可

7.打开你需要加密的excel文件，新增一列为“密文”，在单元格中输入=Md5_String_Calc(A2)回车即可

8.批量操作，把鼠标放在刚刚生成密码的单元格的右下角，有个“+”，点击“+”往下拖拽即可全部生成密文

9.验证是否成功：
