    Lightbulb Export data from Excel to Access Table (ADO) using VBA

    Hi All.

    If you want to export a range of data into an Access table (Either before or 2007 or Post 2007), here is a sub. This also allows you to either create a new table or append an existing table.

    Code:
    Option Explicit
    
    Public Enum TableProperty
        AppendTable = 0
        CreateTable = 1
    End Enum
    
    Private Const strTitle As String = "ExcelFox.com"
    
    Sub ExportRangeIntoAccess(ByVal DB_FilePath As String, ByVal DB_Name As String, _
                                                        ByVal Tbl_Name As String, _
                                                        ByVal xl_SheetName As String, _
                                                        ByVal HeaderYes As Boolean, _
                                                        ByVal TableProp As TableProperty, _
                                            Optional ByVal RangeAddress As String, _
                                            Optional ByVal DefinedRngName As String, _
                                            Optional ByVal ClearTable As Boolean = True)

            .DisplayAlerts = 1
        End With
        
    End Sub
    
    Function IsFileExists(ByVal FilePath As String) As Boolean
        IsFileExists = Len(Dir(FilePath, vbDirectory))
    End Function
    and call the sub like

    Code:
    Sub kTest()
        
        ExportRangeIntoAccess "C:\ExcelFox", "Test_2007.accdb", "MyTable", "Sheet1", True, CreateTable, "A1:K200000", "", False
        
        'ExportRangeIntoAccess "C:\ExcelFox", "Test_2007.accdb", "MyTable", "Sheet1", True, CreateTable, "MyRange", "", False
        'ExportRangeIntoAccess "C:\ExcelFox", "Test_2007.accdb", "MyTable", "Sheet1", True, AppendTable, "A1:K200000", "", True
        'ExportRangeIntoAccess "C:\ExcelFox", "Test_2003.mdb", "MyTable", "Sheet1", True, AppendTable, "A1:K20000", "", True
        'ExportRangeIntoAccess "C:\ExcelFox", "Test_2003.mdb", "MyTable", "Sheet1", True, CreateTable, "A1:K20000", "", False

    hi, I am new to excel vba programming, I used your code to export data from excel to access 2007, works perfectly, except for one problem. if the excel column has more than 255 characters in the rows, then I am getting error "too much data", since the default property for access columns is 'text', how to modify your code to be able to change property to 'memo' if length of data is more than 255? Thanks!

    Hi. I'm not an expert on VBA, I couldn't figure out how "HeaderYes" is determined in above codes. It seems that the codes determine the first row of selected range as HDR, then how does the code determine if the first row is header row or not? I'd appreciate if you point it out. Thanks in advance!
