Question

I am currently able to enter csv file data into Excel VBA by uploading the data via the code below then handling the table, surely not the best way as I am only interested in some of the data and delete the sheet after using the data:

Sub CSV_Import() 
Dim ws As Worksheet, strFile As String 

Set ws = ActiveSheet 'set to current worksheet name 

strFile = Application.GetOpenFilename("Text Files (*.csv),*.csv", ,"Please select text file...") 

With ws.QueryTables.Add(Connection:="TEXT;" & strFile, Destination:=ws.Range("A1")) 
     .TextFileParseType = xlDelimited 
     .TextFileCommaDelimiter = True 
     .Refresh 
End With 
End Sub 

Is it possible to simply load the csv into a two dimensional variant array in VBA rather than going through the use of an excel worksheet?

Answer 1

OK, after looking into this, the solution I have arived at is to use ADODB (requires reference to ActiveX Data Objects, this loads the csv file into array without cycling the rows columns. Does require the data to be in good condition.

Sub LoadCSVtoArray()

strPath = ThisWorkbook.Path & "\"

Set cn = CreateObject("ADODB.Connection")
strcon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strPath & ";Extended Properties=""text;HDR=Yes;FMT=Delimited"";"
cn.Open strcon
strSQL = "SELECT * FROM SAMPLE.csv;"

Dim rs As Recordset
Dim rsARR() As Variant

Set rs = cn.Execute(strSQL)
rsARR = WorksheetFunction.Transpose(rs.GetRows)
rs.Close
Set cn = Nothing

[a1].Resize(UBound(rsARR), UBound(Application.Transpose(rsARR))) = rsARR

End Sub
