我有一个 Excel 文件，其中有 50 个问题，我想在 Java 小程序中包含一份问卷调查。此问卷的答案将存储在我创建的 MySQL 数据库中。
有什么方法可以从我的 Excel 文件中选择所有（或一部分）问题并将它们放入 MySQL 表中的字段（我选择）中？
我环顾四周并加载数据文件听起来像是一个可行的选项，但我想选择哪些问题以及将它们放在哪里。谁能指出我正确的方向？还是我应该简单地复制和粘贴？
任何帮助都会很棒！

将 Excel 数据保存为CSV 格式，然后使用LOAD DATA命令将其导入 MySQL。
关于后者的信息可以在这里找到，例如：

这现在可能看起来有点老了，但会帮助任何其他寻找解决方案的人。
Excel 有官方的 MySQL 插件，用于在 Excel 中导出、导入、附加和编辑 MySQL 数据。
这是链接：http ://dev.mysql.com/doc/refman/5.6/en/mysql-for-excel.html

查看 Excel 将数据保存为 CSV 文件，然后将其加载到 MySQL。尝试根据 MySQL 结构在 Excel 中格式化数据。
