VBA Macro To Open And Modify Files By Looping Through Files In Folder

I would like a macro that will do the following

1) open all CSV files in folder C:\Journals
2) Format Col's B:D to 2 decimal places
3) Save the files



Your assistance is most appreciated

Try this

Code:

---

Sub OpenAndModifySameFileTypes()
   
    Dim strFile As String
    Dim strFileType As String
    Dim strPath As String
    Dim lngLoop As Long
   
    strPath = "C:\Journals"
    strFileType = "*.csv" 'Split with semi-colon if you want to specify the file types. Example ->> "*.xls;*.jpeg;*.doc;*.gif"
   
    For lngLoop = LBound(Split(strFileType, ";")) To UBound(Split(strFileType, ";"))
        strFile = Dir(strPath & "\" & Split(strFileType, ";")(lngLoop))
        Do While strFile <> ""
            With Workbooks.Open(strPath & "\" & strFile)
                With .Sheets(1)
                    .Range("B1:D" & .UsedRange.Rows.Count).NumberFormat = "0.00"
                End With
                .Close 1
            End With
            strFile = Dir
        Loop
    Next lngLoop
    strFile = vbNullString
    strFileType = vbNullString
    strPath = vbNullString
    lngLoop = Empty
   
End Sub

---

Thanks for the help, much appreciated

Hi Excel Fox

I have tried to amend your code to do the following, but cannot get it to work

I would like to:
1) Hide the row where Col A contains data and COl B and C has no value in the same row as Col A
2) I want to delete 50 rows after the last row in Col A containing data

Regards

Howard

Thanks for the help. Where the is a value in Col A and no values in Col B & C, then the row must be hidden. In the attached sample, there is a value in A5, but nothing in Col B & C, therefore Row 5 must be hidden. Kindly amend your code accordingly

I don't want to hurt your pride: I think you will be able to amend the code yourself.

I will certainly give it a bash

Hi snb & Excel Fox

I have amended my code, but when hiding the row manually and saving and then re-opening , I realised that you cannot hide a column in a CSV file as when it its re-opened the row is no longer hidden

Why don't you process a CSV file and save the file as an Excel file, and delete the original CSV file using code?
