Question

I need to output some results as a .csv file, that gets parsed later on by another process. In order to produce these results, I have a huge workbook containing all the macros and functions that I need.

1. Is it possible to "create" a separate .csv file from VBA?
2. Is it possible to use VBA features to write into it instead of just writing in a "raw textual" approach?

Answer 1

Is something like this what you want?

Option Explicit
Sub WriteFile()

  Dim ColNum As Integer
  Dim Line As String
  Dim LineValues() As Variant
  Dim OutputFileNum As Integer
  Dim PathName As String
  Dim RowNum As Integer
  Dim SheetValues() As Variant

  PathName = Application.ActiveWorkbook.Path
  OutputFileNum = FreeFile

  Open PathName & "\Test.csv" For Output Lock Write As #OutputFileNum

  Print #OutputFileNum, "Field1" & "," & "Field2"

  SheetValues = Sheets("Sheet1").Range("A1:H9").Value
  ReDim LineValues(1 To 8)

  For RowNum = 1 To 9
    For ColNum = 1 To 8
      LineValues(ColNum) = SheetValues(RowNum, ColNum)
    Next
    Line = Join(LineValues, ",")
    Print #OutputFileNum, Line
  Next

  Close OutputFileNum

End Sub

Don’t forget you will need to put quotes around any field containing a comma.
