导入 CSV 并替换相应命名工作表中的数据
Import CSV and replace data in corresponding named sheets
请耐心等待，因为我完全没有编写脚本的经验。
我需要帮助的是一个 Google 应用程序脚本，它自动从我的 google 驱动器导入 10 个 .csv 文件，并覆盖包含一个 'dashboard' 的传播 sheet 中的数据sheet、一个'working' sheet等都是CSV导入的sheet，与csv文件名相同。到目前为止，我已经找到了执行此操作的 trial/paid 扩展程序，但我确实找到了这个可以很好地导入数据的脚本，但它将所有数据附加到一个 sheet 而不是替换 sheets与 csv 具有相同的文件名。
我什至不确定脚本是否是最好的方式或 sheet 中的公式是否可行，但我不确定。
非常感谢您的帮助

如果你想替换工作表上的所有数据（而不是追加），可能你可以通过更改此行（在相同的函数 processCsv_() 中）来实现：
