Hi,

I have a data with numbers, which ideally should in series of 50s (i.e. 250-300 or 35000-35050, etc etc). I have attached the sample sheet of numbers,

[TABLE="width: 76"]
<colgroup><col></colgroup><tbody>[TR]
[TD][TABLE="width: 64"]
<colgroup><col width="64" style="width:48pt"> </colgroup><tbody>[TR]

</tbody>[/TABLE]

what result i expect is that,

1) which numbers are missing
2) what is the range of this missing numbers in the series of 50s (i.e. suppose missing number is 65 then range shuld be 50-100)

pls guide.

Excel Facts

VLOOKUP to Left?
Use =VLOOKUP(A2,CHOOSE({1,2},$Z$1:$Z$99,$Y$1:$Y$99),2,False) to lookup Y values to left of Z values.
Sort by date Sort by votes
Give this macro a try...
Rich (BB code): 
Sub ListMissingNumbersAndRange()
  Dim X As Long, Z As Long, LastRow As Long, StartNumber As Long
  Dim Missing As String, Numbers As Variant, NumberRanges() As String
  Const OutputStartCell As String = "B1"
  Const DataCol As String = "A"
  Const StartRow As Long = 1
  LastRow = Cells(Rows.Count, DataCol).End(xlUp).Row
  For X = StartRow + 1 To LastRow
    If Cells(X, DataCol).Value <> Cells(X - 1, DataCol).Value - 1 Then
      For Z = Cells(X - 1, DataCol).Value + 1 To Cells(X, DataCol).Value - 1
        Missing = Missing & " " & Z
      Next
    End If
  Next
  Numbers = Split(Trim(Missing))
  ReDim NumberRanges(0 To UBound(Numbers))
  For X = 0 To UBound(Numbers)
    StartNumber = Numbers(X) - (Numbers(X) Mod 50)
    NumberRanges(X) = StartNumber & " - " & StartNumber + 49
  Next
  Range(OutputStartCell).Resize(UBound(Numbers) + 1) = WorksheetFunction.Transpose(Numbers)
  Range(OutputStartCell).Offset(, 1).Resize(UBound(Numbers) + 1) = WorksheetFunction.Transpose(NumberRanges)
End Sub
Ther e are some constants (the Const statements) that let you control where the data is and where you want the output to go to... adjust them as needed by your setup. Also note that I did not set your ranges like this... 50-100... because doing so would make the end of one range the same as the beginning of the next mean numbers like 100 would belong to two ranges, so I set the end of each range to one less than the beginning of the next (that is, for example, 50-99). If you really want the ranges to overlap as your original message indicated, then change the 49 that I highlighted in red to 50.
