excel - 循环文件，拆分文本并保存文件

问题描述

我有一些 vba 代码循环遍历文件夹中的所有 csv 文件。它保存文件但不将文本拆分为列。

当我使用 F8 单步执行代码时，我可以看到文本被拆分为列，但是在重新打开修改后的文件时，我看不到已拆分的文本。

我正在尝试打开每个文件，将文本拆分为列，然后保存并转到下一个文件。我想对我选择的文件夹中的所有文件执行此操作。每个文件夹可能包含数千个文件。

解决方案

您可能会将文件保存回 csv。您应该以这种方式将文件保存在 xlsx 中：

wb.SaveAs Filename:=split(myfile, ".")(0), FileFormat:=xlOpenXMLWorkbook

请也应用@Luuklag 的建议。
