How to convert two different CSV files into two sheets in the same Excel workbook?

Question

I have a solution which copies the csv data to excel sheet but it works for only 1 CSV file to 1 Excel sheet. How to transfer multiple CSV files to multiple sheets in Excel?

Here is my code:

Dim oExcel  
Set oExcel = CreateObject("Excel.Application")  
With oExcel  
    .DefaultSaveFormat=51  
    .Workbooks.Open sourceFile  
    .Sheets(1).Columns("A").TextToColumns .Range("A1"), , , , , True  
    .Sheets.add
    .ActiveWorkbook.SaveAs outputFile, 51  
    .Quit  
End With

You actually don't need to use TextToColumns. For the first CSV file, the sheet is already there and for the second one, you can open the file as another workbook, then use the Worksheet.Copy method to copy the sheet after the first one.

There you go:

Const xlWorkbookDefault = 51

Dim sourceFile1, sourceFile2, outputFile
Dim xlApp, xlWorkbook1, xlWorkbook2

sourceFile1 = "...\CSV1.csv"
sourceFile2 = "...\CSV2.csv"
outputFile = "...\output.xlsx"

Set xlApp = CreateObject("Excel.Application")
With xlApp
    Set xlWorkbook1 = .Workbooks.Open(sourceFile1)
    Set xlWorkbook2 = .Workbooks.Open(sourceFile2)
    xlWorkbook2.Sheets(1).Copy , xlWorkbook1.Sheets(1)
    xlWorkbook2.Close
    .xlWorkbook1.SaveAs outputFile, xlWorkbookDefault
    .Quit  
End With

To make it more generic, you can adjust the previous code to work with any number of CSV files:

Const xlWorkbookDefault = 51

Dim sourceFiles(5)
Dim outputFile
Dim xlApp, xlWorkbook1, xlWorkbook2

sourceFiles(0) = "...\CSV1.csv"
sourceFiles(1) = "...\CSV2.csv"
sourceFiles(2) = '...
' TODO: Add more files.
outputFile = "...\output.xlsx"

Set xlApp = CreateObject("Excel.Application")
With xlApp
    Set xlWorkbook1 = .Workbooks.Open(sourceFiles(0))
    For i = 1 To UBound(sourceFiles)
        Set xlWorkbook2 = .Workbooks.Open(sourceFiles(i))
        xlWorkbook2.Sheets(1).Copy , xlWorkbook1.Sheets(i)
        xlWorkbook2.Close
    Next
    .xlWorkbook1.SaveAs outputFile, xlWorkbookDefault
    .Quit  
End With
