Javascript 访问、解析和写入.csv数据-谷歌应用程序脚本
我在谷歌电子表格中运行javascript。我正试图上传一个.cs文件,对其进行解析,然后将其写入电子表格。(这是在将.csv数据写入电子表格之前能够对其进行操作的初步步骤)。.csv已成功上载到Google文档列表,但我无法将其写入电子表格。我在测试天气时遇到问题,或者我的脚本是否实际获取了.csv数据,因此我可以对其进行分析。我的脚本包括在下面。我真的很感激任何建议。我尝试了几种变体,当前的变体抛出了一个“csvFile is undefined”错误。我不知道Javascript 访问、解析和写入.csv数据-谷歌应用程序脚本,javascript,parsing,csv,google-apps-script,Javascript,Parsing,Csv,Google Apps Script,我在谷歌电子表格中运行javascript。我正试图上传一个.cs文件,对其进行解析,然后将其写入电子表格。(这是在将.csv数据写入电子表格之前能够对其进行操作的初步步骤)。.csv已成功上载到Google文档列表,但我无法将其写入电子表格。我在测试天气时遇到问题,或者我的脚本是否实际获取了.csv数据,因此我可以对其进行分析。我的脚本包括在下面。我真的很感激任何建议。我尝试了几种变体,当前的变体抛出了一个“csvFile is undefined”错误。我不知道var files=DocsL
