我目前的环境是使用 Javascript、HTML、File API 来上传文件。目前，我一直在研究如何读取 File API 上传的 CSV 文件，例如：

可在此处下载 CSV 文件

例如，将所有列标题和行数据等输出到 HTML 上显示的表格中

大多数在线研究似乎都集中在类似于 JSON 数据的传入 csv 数据上。但我似乎无法找到解析 CSV 文件的文件。任何帮助或指导将不胜感激。

通常 CSV 文件包含由分隔符分隔的单元格，例如;：在您的示例中，分隔符是,. 所以你需要做的是：

1）将您的CSV文件读入一个String，例如您可以命名它input；

2）像这样创建一个字符串数组String[] result = input.split("\\,");；

3）随心所欲地迭代你result的。
