VBA not cycling through and processing all files in folder

Hi all,

I've been working on some code with the help of a fellow board member to cycle through csv files in a folder and modify the date format from DD/MM/YYYY to YYYY-MM-DD, save each exit and move onto the next.

In my original code the macro would cycle through the files sucessfully and display a message telling the user how many files were processed, but upon opening the csv files in wordpad some of the dates would have switched from YYYYY-MM-DD to YYYY-DD-MM, generally these were where the MM-DD were both under 12, i.e. the month was < December.

This code is below:

Option Explicit
 
 
Sub FixDates()
     
     
    Dim SelectFolder As String
    Dim csvFiles As Variant
    Dim csvWb As Workbook
    Dim x As Integer
    
    Application.DisplayAlerts = False

     
     'browse for folder with csv files
    On Error GoTo FixCsvFiles_Error
    SelectFolder = GetFolder("c:\")
    Application.ScreenUpdating = False
    Application.Calculation = xlCalculationAutomatic
     'Check user did not cancel folder selection
    If SelectFolder = "" Then
        MsgBox "No Folder Selected - Cannot continue", vbCritical
        End
    End If
     
    SelectFolder = SelectFolder & "\"
    csvFiles = Dir(SelectFolder & "*.csv")
    Do While csvFiles <> ""
         
        Set csvWb = Workbooks.Open(SelectFolder & csvFiles)
        Range("F2").Select
        ActiveCell.FormulaR1C1 = "=TEXT(RC[-2],""YYYY-MM-DD"")"
        Selection.AutoFill Destination:=Range("F2:F228")
        Range("F2:F228").Select
        Selection.Copy
        Range("D2").Select
        Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False
        Selection.PasteSpecial Paste:=xlPasteFormats, Operation:=xlNone, _
        SkipBlanks:=False, Transpose:=False
        Range("F2").Select
        Range(Selection, Selection.End(xlDown)).Select
        Application.CutCopyMode = False
        Selection.ClearContents
        Range("A229:E300").Select
        Selection.ClearContents
        x = x + 1
        Application.DisplayAlerts = False
        csvWb.Close SaveChanges:=True
        Application.DisplayAlerts = True
        csvFiles = Dir
    Loop
    Application.ScreenUpdating = True
    MsgBox "A total of " & CStr(x) & " files processed", vbInformation
    On Error GoTo 0
    Application.DisplayAlerts = True
    Exit Sub
     
FixCsvFiles_Error:
     
    MsgBox "Error " & Err.Number & " (" & Err.Description & ") in procedure FixCsvFiles of Module2"
End Sub
 
 
Function GetFolder(strPath As String) As String
    Dim fldr As FileDialog
    Dim sItem As String
     
     
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "BROWSE TO FOLDER LOCATION WITH CSV FILES"
        .AllowMultiSelect = False
        .InitialFileName = strPath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

The improved code provided by Philb1 sucessfully changed the dates in the first csv file processed but doesn't cycle through the remainder of the files in the folder, or display a message telling the user how many files have been processed.

The code is:

    End With

Would anyone know what's wrong with the code above and why it's stopped cycling through the files?
