    Combining transpose, Count and IF

    Hi everyone. I'm having some serious issues with a data set from hell. I managed to merge 3 separate excel files using a combination of IF's, VLOOKUP and sacrificing small animals.

    But now I'm hopelessly stuck. the data set contains about 5000 students but their marks are organized in rows and not columns. I need it in columns for SPSS to like it. (so it should look like Sheet 2)

    However, there are over 450 subjects and I can only use a subject for analysis if there are more than 100 students who took that subject. I need to somehow transpose the subjects and marks into a new sheet but only if the subject count exceeds 100. Essentially it needs to run down column B and D in Sheet1 and if there are more than 100 students that have taken a specific subject then it should write that subject to a new column in a new sheet and allocate the relevant marks to the relevant student number.

    So for argument's sake, let's assume that only Accounting, English, Mathematics, Chemistry 171, and Calculus 158 had more than 100 counts in Sheet 1. This produces Sheet2. It can chuck the other stuff out.

    I hope i made it clear what the issue is. I would appreciate some help an awful lot as I don't have time to learn VBA in a day.

    The easy way is to just pivot it, but here is some code to do it

    Public Sub BasicLoop()
    Dim this As Worksheet
    Dim sh As Worksheet
    Dim rowLast As Long
    Dim rowMatch As Long
    Dim colMatch As Long
    Dim i As Long
        Application.ScreenUpdating = False
        Set this = ActiveSheet
        Set sh = Worksheets.Add
        sh.Name = "Formatted"
        sh.Range("A1").Value = "Student"
        With this
            rowLast = .Cells(.Rows.Count, "A").End(xlUp).Row
            For i = 2 To rowLast
                rowMatch = 0
                On Error Resume Next
                rowMatch = Application.Match(.Cells(i, "A").Value, sh.Columns(1), 0)
                On Error GoTo 0
                If rowMatch = 0 Then
                    rowMatch = sh.Cells(sh.Rows.Count, "A").End(xlUp).Row + 1
                    sh.Cells(rowMatch, "A").Value = .Cells(i, "A").Value
                End If
                If .Cells(i, "B").Value <> "" Then
                    colMatch = 0
                    On Error Resume Next
                    colMatch = Application.Match(.Cells(i, "B").Value, sh.Rows(1), 0)
                    On Error GoTo 0
                    If colMatch = 0 Then
                        colMatch = sh.Cells(1, sh.Columns.Count).End(xlToLeft).Column + 1
                        sh.Cells(1, colMatch).Value = .Cells(i, "B").Value
                    End If
                    sh.Cells(rowMatch, colMatch).Value = .Cells(i, "C").Value
                End If
            Next i
            sh.Rows(1).Font.Bold = True
        End With
        Application.ScreenUpdating = True
    End Sub

    Wow. That worked flawlessly. You sir are a saint. I'll study the macro later to day to try to learn from it. Thank you aigain.

    Sub M_snb()
        sp = Sheet3.Cells(1).CurrentRegion.Rows(1)
        ReDim sq(0, UBound(sp, 2))
        sn = [if(sheet1!A1:A1000="","",if(Column(A1:C1000)=1,A1:A1000,if($B1:$B1000="",offset(A1:C1000,,2),$A1:$C1000)))]
        With CreateObject("scripting.dictionary")
          For j = 2 To UBound(sn)
            st = .Item(sn(j, 1))
            If VarType(st) = 0 Then st = sq
            st(0, 0) = sn(j, 1)
            If Not IsError(Application.Match(sn(j, 2), sp, 0)) Then st(0, Application.Match(sn(j, 2), sp, 0) - 1) = sn(j, 3)
            .Item(sn(j, 1)) = st
          Sheet3.Cells(2, 1).Resize(.Count, UBound(sp, 2) + 1) = Application.Index(.items, 0, 0)
        End With
    End Sub
