循环遍历当前目录下的所有文件

Question

我的宏要求我实际打开一个逗号分隔的文件， 运行我的宏，保存文件然后重复。

我需要一个宏来遍历当前目录中的所有文件进行更改然后保存自己。

文件目录是
X:\New Gas Team 2016\Incorrect TTZ Database\Read Flows\UMR

转换后的文件需要保存到以下
X:\New Gas Team 2016\Incorrect TTZ Database\Read Flows\UMR\converted

作为启用 Excel 宏的工作簿，文件名与转换前相同。

您将使用Dir 函数。这是您将代码嵌套在其中的循环示例：

'Get a count of the files to be merged
f = Dir(fol & "\" & y & "*Office Hrs.xls*")
Do While Len(f) > 0
    fc = fc + 1
    f = Dir

    'Fail safe escape option
    If fc > 600 & Len(f) > 0 Then
        MsgBox "An error has occurred causing it to appear that there are more than 600 files in the specified folder.", vbOKOnly, "Overly Large File Count"
            Application.Calculation = xlCalculationAutomatic
            Application.ScreenUpdating = True
            End
    End If
Loop

另外，你应该从你的宏中删除Select，几乎所有它出现的地方。选择不是必需的，会减慢您的代码速度。比如：

Range("A1").Select
ActiveCell.FormulaR1C1 = "Transaction_Type"

应该是

Range("A1").Value = "Transaction_Type"

此外，正如我的示例所暗示的那样，除非您实际上将 Excel 公式添加到单元格中，否则您应该设置 .Value 属性
