I\'m a novice programmer trying to automate some repetitive workplace tasks that should be done by a clever script instead of humans. I\'ve done some VBA and Java, but very

The code below works for converting 2D arrays in CSV. I have not written the code, but have tested it and it works!

' SaveAsCSV saves an array as csv file. Choosing a delimiter different as a comma, is optional.
'
' Syntax:
' SaveAsCSV dMyArray, sMyFileName, [sMyDelimiter]
'
' Examples:
' SaveAsCSV dChrom, app.path & "\Demo.csv"       --> comma as delimiter
' SaveAsCSV dChrom, app.path & "\Demo.csv", ";"  --> semicolon as delimiter

Public Sub SaveAsCSV(MyArray() As Variant, sFilename As String, Optional sDelimiter As String = ",")

Dim n As Long 'counter
Dim M As Long 'counter
Dim sCSV As String 'csv string to print

On Error GoTo ErrHandler_SaveAsCSV


'check extension and correct if needed
If InStr(sFilename, ".csv") = 0 Then
  sFilename = sFilename & ".csv"
Else
  While (Len(sFilename) - InStr(sFilename, ".csv")) > 3
    sFilename = Left(sFilename, Len(sFilename) - 1)
  Wend
End If

'If MultiDimensional(MyArray()) = False Then '1 dimension

  'save the file
'  Open sFileName For Output As #7
'  For n = 0 To UBound(MyArray(), 1)
'    Print #7, Format(MyArray(n, 0), "0.000000E+00")
'  Next n
'  Close #7

'Else 'more dimensional

  'save the file
  Open sFilename For Output As #7
  For n = 1 To UBound(MyArray(), 1)
    sCSV = ""
    For M = 1 To UBound(MyArray(), 2)
      sCSV = sCSV & Format(MyArray(n, M)) & sDelimiter
    Next M
    sCSV = Left(sCSV, Len(sCSV) - 1) 'remove last Delimiter
    Print #7, sCSV
  Next n
  Close #7

'End If

Exit Sub
