VBA Multiple FreeFile Exports to CSV - vba

Question

I'm trying to use the Freefile to export to text files. The process is taking a worksheet with many columns and for each column, exporting it as text.
The problem I've been having is getting the error 55 code "file is already open".
Because I want the column range as the input to be of a variable length, I don't know for certain how many freefile commands I would need.
For j = intColumOffsett + 1 To intLastColumn
strDate = wkSource.Cells(1, j).Value
strNewFile = strDirectory & strDate & " New.csv"
For i = 1 To intLastRow
strTarget = strTarget & wkSource.Cells(i, 1).Value & ","
strTarget = strTarget & wkSource.Cells(i, 2).Value & ","
strTarget = strTarget & wkSource.Cells(i, 3).Value & ","
strTarget = strTarget & strDate & ","
strTarget = strTarget & wkSource.Cells(i, j).Value
' It's this this section I'm not sure about \/
'Set strNewFile = Nothing
'Stop
iF1 = FreeFile(j)
'Close #iF1
On Error GoTo Error:
Open strNewFile For Output As #iF1
Print #iF1, strTarget
Debug.Print strTarget
strTarget = ""
Error:
MsgBox (Err.Description)
Next i
Close #iF1
Next j
How can I avoid these errors will exporting as many new CSV's as I needed depending on the unknown number of columns from the source....?????

FreeFile will generate a new file number each time you call it.
But in your code, you were calling it for each row.
And you error handling wasn't appropriate, so I added a sub to show how you should use! ;)
Sub MultiFreeFiles()
'''...
For j = intColumOffsett + 1 To intLastColumn
strDate = wkSource.Cells(1, j).Value
strNewFile = strDirectory & strDate & " New.csv"
iF1 = FreeFile
On Error GoTo Error:
Open strNewFile For Output As #iF1
For i = 1 To intLastRow
strTarget = vbNullString
With wkSource
strTarget = strTarget & .Cells(i, 1).Value & ","
strTarget = strTarget & .Cells(i, 2).Value & ","
strTarget = strTarget & .Cells(i, 3).Value & ","
strTarget = strTarget & strDate & ","
strTarget = strTarget & .Cells(i, j).Value
End With 'wkSource
Debug.Print strTarget
Print #iF1, strTarget
Next i
Close #iF1
Next j
'''...
Exit Sub
Error:
MsgBox (Err.Description)
Resume
End Sub
