我在google电子表格中运行javascript。我正在尝试上传.cs文件，解析它，并将其写入电子表格。 （这是在将.csv数据写入电子表格之前对其进行操作的初步步骤）。 .csv已成功上传到Google文档列表，但是 我无法将其写入电子表格。 我无法测试天气或无法测试我的脚本实际上是获取.csv数据，所以我可以解析它。我的脚本包含在下面。我真的很赞赏任何建议。我尝试了几种变体，当前的一种是抛出“csvFile is undefined”错误。我不知道var files = DocsList.getFiles(fileBlob); var csvFile = ""; csvFile = files.getContentAsString();是否有效。我该如何测试？运行谷歌调试器总是最终我的变量都是未定义的，因为没有用户上传文件。谢谢你的期待。 -Jamie

在doPost功能结束时，您可以使用return app.close();自动关闭UI，无需显示“已完成上传”的标签，工作表会显示数据，因此我们知道上传过程正确。 ..
编辑：
这是代码的“紧凑”版本，没有大量的注释和一些改进，请注意我使用setValues()无需循环将数组数据写回电子表格的方式。用户界面也略有修改。
我在你的其他帖子中看到你想要从驱动器中删除上传的文件，所以我通过直接从blob获取字符串内容跳过了这一步（参见代码中的注释）
