回复：使用文件对话框选择器和列定义编写打开 CSV 的脚本。嗨，杰夫，

谢谢，有效。 只是为了完整性，为什么在包含列规范时 open 函数不起作用？
安迪回复：使用文件对话框选择器和列定义编写打开 CSV 的脚本。

你能用吗选择文件()然后在 Open() 中使用该文件名？

 

chosen_file=pick file("Choose a .csv file", "$DESKTOP", {"Text files|csv;"});

open(chosen_file);

使用文件对话框选择器和列定义编写打开 CSV 的脚本。

你好，

 

致力于自动化分析，并在导入 csv 文件的第一步中陷入困境。 我的方法是使用自动生成的脚本作为基础。

以下脚本适用于我的测试文件，我想修改为使用文件浏览器来选择文件而不是当前的硬编码。

脚本文档指出，如果文件路径字符串不存在，则将使用文件对话框。 本着这种精神，我删除了“$DESKTOP/test.csv”字符串，但这只是返回请求字符串的错误。 如果我在没有列定义的情况下进行打开，例如 dt =open();然后会出现文件对话框，但会出现导入对话框，并且需要单击我想避免的情况。 如何获得文件对话框窗口来选择文件以及最终数据表的列定义？

安迪
