Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Finding the Address of the Lowest Value in a Range.
When writing a macro, you can find the lowest value in a range of cells by using the WorksheetFunction method to apply the MIN worksheet function. You may need, however, to not only find the lowest value in the range, but also the address of the first cell that contains that value.
One simple way is to simply step through the range you want to examine and derive both the lowest value and the address of the cell being examined, as in the following:
Function FindLowestAddr(pRng As Range) As String Application.Volatile MinVal = pRng.Cells(1).Value MinAddr = pRng.Cells(1).Address For Each c in pRng If c.Value < MinVal Then MinVal = c.Value MinAddr = c.Address End If Next c FindLowestAddr = MinAddr End Function
Note that this approach doesn't rely upon the MIN worksheet function at all. There is a drawback to it, however—it doesn't differentiate between cells that contain numeric values and those that don't. In other words, if the range passed to the function contains a blank cell, that cell is considered to contain a zero value, which may very well be the lowest value in the range.
One way around this is to rely upon worksheet functions from within the macro. The following macro uses both the MIN and MATCH worksheet functions to determine the location of the minimum value and then the index (offset) of that cell within the range.
Function GetAddr(rng As Range) As String Dim dMin As Double Dim lIndex As Long Dim sAddress As String Application.Volatile With Application.WorksheetFunction dMin = .Min(rng) lIndex = .Match(dMin, rng, 0) End With GetAddr = rng.Cells(lIndex).Address End Function
It should be noted that if you are using the macro only to discover the address because you figured there was no way to derive the desired information without the macro, then you can do away with the macro entirely by using a worksheet formula. For instance, if you want to determine the address of the lowest-valued cell in the named range MyRange, you could use the following:
