Good evening I have a sample of data below. I have about 200,000 rows. I am looking for a formula or subroutine that will find the school month and calculate the frequency like below. Here is an example I would like to check Lincoln School in the SEPT column and count how many cells are 1 to 4. In the example it would be 4. Any help would be appreciated.
<style type="text/css">
table.tableizer-table {

margin: 3px;
border: 1px solid #CCC ;
}
.tableizer-table th {
background-color: #104E8B ;
color: #FFF ;
font-weight: bold;
}
</style>
<table class="tableizer-table">

Start here assuming your range of data starts in A1. Modify as necessary

=COUNTIFS($B$2:$B$20,B2,$D$2:$D$20,">0",$D$2:$D$20,"<5"), this will give you the result for Sept, Lincoln between 0 and 5

yeah thanks alansideman I was using =SUMPRODUCT(($B$2:$B$20=$O2)*($D$2:$D$20={1,2,3,4})) but the problem I have is that when I go to pull down the months I need the formula to update. The same will occur with your formula,

Given the size of the data, I suspect any formula solution may be very slow to calculate, hence I'm suggesting a macro (though I haven't tested it with that much data either).

Code: 
Sub CountRanges()
  Dim d As Object
  Dim a As Variant, b As Variant
  Dim i As Long, j As Long, k As Long, uba2 As Long, cols As Long, baseRow As Long, col As Long
  
  Set d = CreateObject("Scripting.Dictionary")
  d.CompareMode = 1
  a = Range("B1", Range("M" & Rows.Count).End(xlUp)).Value
  uba2 = UBound(a, 2)
  cols = uba2 - 2
  ReDim b(1 To Rows.Count, 1 To 6)
  
  For i = 2 To UBound(a)
    If Not d.exists(a(i, 1)) Then
      For k = 1 To cols
        b(d.Count * cols + k, 1) = a(i, 1)
        b(d.Count * cols + k, 2) = a(1, k + 2)
      Next k
      d(a(i, 1)) = d.Count
    End If
    baseRow = d(a(i, 1)) * cols + 1
    For j = 3 To uba2
      Select Case a(i, j)
        Case Is >= 16: col = 6
        Case Is >= 11: col = 5
        Case Is >= 5: col = 4
        Case Is >= 1: col = 3
        Case Else: col = 0
      End Select
      If col > 0 Then b(baseRow + j - 3, col) = b(baseRow + j - 3, col) + 1
    Next j
  Next i
  Application.ScreenUpdating = False
  With Range("O1").Resize(d.Count * cols + 1, UBound(b, 2))
    .Offset(1).Resize(.Rows.Count - 1).Value = b
    .SpecialCells(xlBlanks).Value = 0
    With .Rows(1)
      .NumberFormat = "@"
      .Value = Array("School", "Month", "1-4", "5-10", "11-15", "16+")
    End With
    .Columns.AutoFit
  End With
  Application.ScreenUpdating = True
End Sub

Hi,

I am sure Peter's vba code works faster given the size of the data. If you still need a formula, you may try this -

=COUNTIFS($B$2:$B$20,$B26,OFFSET($C$1,1,MATCH($C26,$D$1:$M$1,0),ROWS($B$2:$B$20),1),">=1",OFFSET($C$1,1,MATCH($C26,$D$1:$M$1,0),ROWS($B$2:$B$20),1),"<=4")


Assuming data is in A1:M20 and output range is B25:G35

The formula can be copied for a column and needs to be updated for other conditions: 5-10, 11-15 and 16+. This hard coding can also be avoided by using helper cells. Hope this helps.

Regards.

You are very welcome. :)


If you did want to try a formula solution, and the school/month columns were pre-populated, you could try this SUMPRODUCT formula. It should be less onerous than using OFFSET.
Q1:T1 house the lower bound of each range.
Formula in Q2 is copied across to T2 and down
Column U is empty (at least no numerical values)
