Excel Macro - Convert CSV files into single Excel Sheet

Excel Macro - Merge all CSV files from selected folder and then convert it into single Excel Sheet (xls format)

Following macro will ask user to select a folder with csv files,

-Then merge all csv files into single file

-Then convert the merged csv file into excel sheet with xls format

-Finally you will get all the data from multiple csv files into single excel sheet (xls format) :-)

' Start Code

Declare Function OpenProcess Lib "kernel32" _
(ByVal dwDesiredAccess As Long, _
ByVal bInheritHandle As Long, _
ByVal dwProcessId As Long) As Long

Declare Function GetExitCodeProcess Lib "kernel32" _
(ByVal hProcess As Long, _
lpExitCode As Long) As Long

Public Const STILL_ACTIVE = &H103

Public Sub ShellAndWait(ByVal PathName As String, Optional WindowState)
Dim hProg As Long
Dim hProcess As Long, ExitCode As Long
'fill in the missing parameter and execute the program
If IsMissing(WindowState) Then WindowState = 1
hProg = Shell(PathName, WindowState)
'hProg is a "process ID under Win32. To get the process handle:
hProcess = OpenProcess(PROCESS_QUERY_INFORMATION, False, hProg)
'populate Exitcode variable
GetExitCodeProcess hProcess, ExitCode
Loop While ExitCode = STILL_ACTIVE
End Sub

Sub Merge_CSV_Files()
Dim BatFileName As String
Dim TXTFileName As String
Dim XLSFileName As String
Dim FileExtStr As String
Dim FileFormatNum As Long
Dim DefPath As String
Dim Wb As Workbook
Dim oApp As Object
Dim oFolder
Dim foldername

'Create two temporary file names
BatFileName = Environ("Temp") & _
"\CollectCSVData" & Format(Now, "dd-mm-yy-h-mm-ss") & ".bat"
TXTFileName = Environ("Temp") & _
"\AllCSV" & Format(Now, "dd-mm-yy-h-mm-ss") & ".txt"

'Folder where you want to save the Excel file
DefPath = Application.DefaultFilePath
If Right(DefPath, 1) <> "\" Then
DefPath = DefPath & "\"
End If

'Set the extension and file format
If Val(Application.Version) < 12 Then
'You use Excel 97-2003
FileExtStr = ".xls": FileFormatNum = -4143
'You use Excel 2007
FileExtStr = ".xlsx": FileFormatNum = 51
'If you want to save as xls(97-2003 format) in 2007 use
'FileExtStr = ".xls": FileFormatNum = 56

End If

'Name of the Excel file with a date/time stamp
XLSFileName = DefPath & "MasterCSV " & _
Format(Now, "dd-mmm-yyyy h-mm-ss") & FileExtStr

'Browse to the folder with CSV files
Set oApp = CreateObject("Shell.Application")
Set oFolder = oApp.BrowseForFolder(0, "Select folder with CSV files", 512)
If Not oFolder Is Nothing Then
foldername = oFolder.Self.Path
If Right(foldername, 1) <> "\" Then
foldername = foldername & "\"
End If

'Create the bat file
Open BatFileName For Output As #1
Print #1, "Copy " & Chr(34) & foldername & "*.csv" _
& Chr(34) & " " & TXTFileName
Close #1

'Run the Bat file to collect all data from the CSV files into a TXT file
ShellAndWait BatFileName, 0
If Dir(TXTFileName) = "" Then
MsgBox "There are no csv files in this folder"
Kill BatFileName
Exit Sub
End If

'Open the TXT file in Excel
Application.ScreenUpdating = False
Workbooks.OpenText Filename:=TXTFileName, Origin:=xlWindows, StartRow _
:=1, DataType:=xlDelimited, TextQualifier:=xlDoubleQuote, _
ConsecutiveDelimiter:=False, Tab:=False, Semicolon:=False, Comma:=True, _
Space:=False, Other:=False

'Save text file as a Excel file
Set Wb = ActiveWorkbook
Application.DisplayAlerts = False
Wb.SaveAs Filename:=XLSFileName, FileFormat:=FileFormatNum
Application.DisplayAlerts = True

Wb.Close savechanges:=False
MsgBox "You find the Excel file here: " & vbNewLine & XLSFileName

'Delete the bat and text file you temporary used
Kill BatFileName
Kill TXTFileName
