Hi all,

I am trying to develop a piece of code that will count the number of non-blank cells from a specified range.

Here is what I have thus far:

Public Function CountDataRows() As Long
 'Counts the number of non-blank cells from a START cell range. Loops through the range until empty cell is found. Returns the total number of rows that contain data within the 'specified range/column. Note: Is dependant on each row having a value.

Dim wks As worksheet
Dim wkb As Workbook
Dim rng As Range
Dim Counter As Long

Set wkb = ActiveWorkbook
Set wks = wkb.Sheets("Test")
Set rng = wks.Range("testrow")

    With wks
        Counter = 0
    
        Do Until wks.Range("testrow").Offset(Counter, 0) Is Not Empty
    
        Counter = Counter + 1
    
        Loop
    End With

CountDataRows = Counter

End Function 

Open in new window


Does anyone have any ideas on how to improve upon this?

You probably need something like this

Public Function CountDataRows() As Long
 'Counts the number of non-blank cells from a START cell range. Loops through the range until empty cell is found. Returns the total number of rows that contain data within the 'specified range/column. Note: Is dependant on each row having a value.

Dim wks As worksheet
Dim wkb As Workbook
Dim rng As Range
Dim cel As Range
Dim Counter As Long

Set wkb = ActiveWorkbook
Set wks = wkb.Sheets("Test")
Set rng = wks.Range("testrow")

        Counter = 0
    
        for each cel in rng
        if isempty(cel) then
        Counter = Counter + 1
        end if
        next cel

CountDataRows = Counter

End Function

HI,

You could you use this method (but it only works within the .UsedRange area)

Set myRange = Range("b1:b2")
On Error Resume Next
BlankCells = myRange.SpecialCells(xlCellTypeBlanks).Count
On Error GoTo 0
NonBlankCells = myRange.Cells.Count - BlankCells

Open in new window


If you do not know if your range is within the .UsedRange area

pls try

Set myRange = Range("a1:b3")

Set IntersectRange = Intersect(ActiveSheet.UsedRange, myRange)
On Error Resume Next
IntersectCellsCount = IntersectRange.Cells.Count
On Error GoTo 0
CellsOutsideUsedRange = myRange.Cells.Count - IntersectCellsCount
On Error Resume Next
UsedRangeEmptyCellsCount = IntersectRange.SpecialCells(xlCellTypeBlanks).Count
On Error GoTo 0
BlankCells = UsedRangeEmptyCellsCount + CellsOutsideUsedRange

NonBlankCells = myRange.Cells.Count - BlankCells

Open in new window

EDIT

to find the last empty cell before something else pls

Set myRange = Range("a1").End(xlDown).Offset(-1, 0)
'Or
CellsCount = Range(Range("A1"), Range("a1").End(xlDown).Offset(-1, 0)).Cells.Count

Open in new window
