How to query UTF-8 encoded CSV-files with VBA in Excel 2010?

Question

I would like to query an UTF-8 encoded CSV file using VBA in Excel 2010 with the following database connection:

provider=Microsoft.Jet.OLEDB.4.0;;data source         


        

Answer 1

The following procedure extracts the entire CSVfile into a new Sheet, clearing the BOM from the Header. It has the Path, Filename and BOM string as variables to provide flexibility.

Use this procedure to call the Query procedure

Sub Qry_Csv_Utf8()
Const kFile As String = "UTF8 .csv"
Const kPath As String = "D:\StackOverFlow\Temp\"
Const kBOM As String = "\xEF\xBB\xBF"
    Call Ado_Qry_Csv(kPath, kFile, kBOM)
End Sub

This is the Query procedure

Sub Ado_Qry_Csv(sPath As String, sFile As String, sBOM As String)
Dim Wsh As Worksheet
Dim AdoConnect As ADODB.Connection
Dim AdoRcrdSet As ADODB.Recordset
Dim i As Integer

    Rem Add New Sheet - Select option required
    'With ThisWorkbook           'Use this if procedure is resident in workbook receiving csv data
    'With Workbooks(WbkName)     'Use this if procedure is not in workbook receiving csv data
    With ActiveWorkbook         'I used this for testing purposes
        Set Wsh = .Sheets.Add(After:=.Sheets(.Sheets.Count))
        'Wsh.Name = NewSheetName        'rename new Sheet
    End With

    Set AdoConnect = New ADODB.Connection
    AdoConnect.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
        "Data Source=" & sPath & ";" & _
        "Extended Properties='text;HDR=Yes;FMT=Delimited(,);CharacterSet=65001'"

    Set AdoRcrdSet = New ADODB.Recordset
    AdoRcrdSet.Open Source:="SELECT * FROM [" & sFile & "]", _
        ActiveConnection:=AdoConnect, _
        CursorType:=adOpenDynamic, _
        LockType:=adLockReadOnly, _
        Options:=adCmdText

    Rem Enter Csv Records in Worksheet
    For i = 0 To -1 + AdoRcrdSet.Fields.Count
        Wsh.Cells(1, 1 + i).Value = _
            WorksheetFunction.Substitute(AdoRcrdSet.Fields(i).Name, sBOM, "")
    Next
    Wsh.Cells(2, 1).CopyFromRecordset AdoRcrdSet

End Sub
