Find Number Between 2 Numbers

Excel and most MS Office Applications, have a Find feature than can be use to find a specified value, or text string, in a range, Worksheet, or Workbook. However, no such feature exists where we can tell Excel to find the first occurrence of a number that is between a Minimum number and a maximum number. We can however use some Excel VBA macro code to do it for us.

Loops Are Too Slow

Most would go with a loop to get a number between a nominated range . However, this can be extremely slow and horribly inefficient if  the Worksheet contain thousands of used cells. The method below makes use of the SpecialCells method to ensure we are only checking numeric cells.

Search All Cells or Only Selection

The code works in the same way as the standard Find feature does. That is, search ALL cells on the Worksheet if only a single cell is selected, or search ONLY the selected cells if more than one cell is selected.

If will locate and select the first cell, that has a value between (not equal to) the specified min and max. It searches by rows. Note, it will not locate a zero value.

Sub GetBetween()

Dim strNum As String

Dim lMin As Long, lMax As Long

Dim rFound As Range, rLookin As Range

Dim lFound As Long, rStart As Range

Dim rCcells As Range, rFcells As Range

Dim lCellCount As Long, lcount As Long

Dim bNoFind As Boolean



    strNum = InputBox("Please enter the lowest value, then a comma, " _

        & "followed by the highest value" & vbNewLine & _

        vbNewLine & "E.g. 1,10", "GET BETWEEN")

        

        If strNum = vbNullString Then Exit Sub

         On Error Resume Next

        lMin = Left(strNum, InStr(1, strNum, ","))

        If Not IsNumeric(lMin) Or lMin = 0 Then

            MsgBox "Error in your entering of numbers, or Min was a zero", vbCritical, "Ozgrid.com"

            Exit Sub

        End If

        

        lMax = Replace(strNum, lMin & ",", "")

        If Not IsNumeric(lMax) Or lMax = 0 Then

            MsgBox "Error in your entering of numbers, or Max was a zero", vbCritical, "Ozgrid.com"

            Exit Sub
