Split2 - A Split variant that parses multiple lines of text

' A Split variant that parses a string that contains
' row and column separators, and returns a 2-dimensional array
'
' the result String array has a number of columns equal
' to the highest number of fields in individual text lines

Function Split2(ByVal Text As String, Optional ByVal RowSeparator As String = _
    vbCrLf, Optional ByVal ColSeparator As String = ",") As String()
    Dim lines() As String
    Dim cols() As String
    Dim r As Long
    Dim c As Long
    
    ' first, split the string in lines
    lines() = Split(Text, RowSeparator)
    ' initialize the result array
    ' start with just one column
    ReDim res(UBound(lines), 0) As String
    
    ' parse each line of text
    For r = 0 To UBound(lines)
        cols() = Split(lines(r), ColSeparator)
        
        ' resize the result array if necessary
        If UBound(cols) > UBound(res, 2) Then
            ReDim Preserve res(UBound(lines), UBound(cols)) As String
        End If
        ' copy the individual values
        For c = 0 To UBound(cols)
            res(r, c) = cols(c)
        Next
    Next
        
    Split2 = res()
    
End Function
