        workbook.easy_addWorksheet_2 ("Second tab")
        Set xlsTable = workbook.easy_getSheetAt(1).easy_getExcelTable()
        xlsTable.easy_getCell_2("A1").setValue ("Data added by Tutorial39")

        For Column = 0 To 4
            xlsTable.easy_getCell(1, Column).setValue ("Data " & (Column + 1))

        ' Confirm conversion of CSV to Excel
        If workbook.easy_getError() = "" Then
            Me.Label1.Caption = Me.Label1.Caption & vbCrLf & "File successfully created."
            Me.Label1.Caption = Me.Label1.Caption & vbCrLf & "Error: " & workbook.easy_getError()

End Sub

Overloaded methods
For methods with same name but different parameters, only the first method overload retains the original name. Subsequent overloads are uniquely renamed by appending to the method name '_2', '_3', etc (method, method_2, method_3), an integer that corresponds to the order of declaration that can be found in EasyXLS.h, a file that comes with EasyXLS installation.
