Excel加密攻略：如何批量快速加密多个文件
在处理敏感数据时，确保Excel文件的安全性至关重要。Excel提供了多种加密方式，可以帮助我们保护数据不被未授权访问。本文将详细介绍如何在Excel中加密单个文件，以及如何批量快速加密多个文件。
一、Excel加密方法
1. 单个文件加密
（1）打开Excel文件，点击“文件”菜单，选择“另存为”。
（2）在“另存为”对话框中，选择保存位置，然后点击“工具”按钮。
（3）在弹出的下拉菜单中选择“常规选项”。
（4）在“常规选项”对话框中，勾选“加密文件内容”复选框，然后输入密码。
（5）点击“确定”按钮，保存文件。此时，文件会被加密，只有输入正确的密码才能打开。
2. 批量快速加密多个文件
（1）将需要加密的Excel文件放入一个文件夹中。
（2）打开命令提示符（Windows系统）或终端（macOS系统）。
（3）进入包含Excel文件的文件夹，使用以下命令：
```
