Import data from a text file (ADO)
2002-04-02 ADO 2 786
The procedure below can be used to get an ADO recordset from a text file and fill in the result in a worksheet.
Sub GetTextFileData(strSQL As String, strFolder As String, rngTargetCell As Range)
' example: GetTextFileData "SELECT * FROM filename.txt", "C:\FolderName", Range("A3")
' example: GetTextFileData "SELECT * FROM filename.txt WHERE fieldname = 'criteria'", "C:\FolderName", Range("A3")
Dim cn As ADODB.Connection, rs As ADODB.Recordset, f As Integer
If rngTargetCell Is Nothing Then Exit Sub
Set cn = New ADODB.Connection
On Error Resume Next
cn.Open "Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=" & strFolder & ";Extensions=asc,csv,tab,txt;"
On Error GoTo 0
If cn.State <> adStateOpen Then Exit Sub
Set rs = New ADODB.Recordset
On Error Resume Next
rs.Open strSQL, cn, adOpenForwardOnly, adLockReadOnly, adCmdText
On Error GoTo 0
If rs.State <> adStateOpen Then
cn.Close
Set cn = Nothing
Exit Sub
End If
' the field headings
For f = 0 To rs.Fields.Count - 1
rngTargetCell.Offset(0, f).Formula = rs.Fields(f).Name
Next f
rngTargetCell.Offset(1, 0).CopyFromRecordset rs ' works in Excel 2000 or later
'RS2WS rs, rngTargetCell ' works in Excel 97 or earlier
rs.Close
Set rs = Nothing
cn.Close
Set cn = Nothing
End Sub
The procedure can be used like this:Sub TestGetTextFileData()
Application.ScreenUpdating = False
Workbooks.Add
GetTextFileData "SELECT * FROM filename.txt", "C:\FolderName", Range("A3")
' GetTextFileData "SELECT * FROM filename.txt WHERE fieldname = 'criteria'", "C:\FolderName", Range("A3")
Columns("A:IV").AutoFit
ActiveWorkbook.Saved = True
End Sub
Replace filename.txt with the name of the text file you want to get data from. Use square brackets around the filename if it contains any space characters:
"SELECT * FROM [file name.txt]"
Replace C:\FolderName with the name of the folder where the text file is saved.
The first row in the text file will be used as column headings/field names.
Each column with data must be separated with the list separator character that is used in the regional settings in the Control Panel. In Norway this usually is a semicolon (;), in other countries this can be a comma (,).
See information about using a Schema.ini file to set information about e.g. column data types and separator characters.

The macro examples assumes that your VBA project has added a reference to the ADO object library. You can do this from within the VBE by selecting the menu Tools, References... and selecting the Microsoft ActiveX Data Objects x.x Object Library.
