Detect if range is empty

Question

I want to check if a range in Excel is empty.

How do I write in VBA code:

If Range("A38":"P38") is empty

Answer 1

Found a solution from the comments I got.

Sub TestIsEmpty()
    If WorksheetFunction.CountA(Range("A38:P38")) = 0 Then
        MsgBox "Empty"
    Else
        MsgBox "Not Empty"
    End If
End Sub

Answer 2

If you find yourself in a situation where you can’t use CountA then it's much faster to first store your range as an array and loop on the array data than it is to loop on range/cell data.

Function IsRangeEmpty(ByVal rng As Range) As Boolean
    'Converts a range to an array and returns true if a value is found in said array
    
    Dim area As Range
    For Each area In rng.Areas
        
        If area.Cells.Count > 1 Then
        
            'save range as array
            Dim arr As Variant
            arr = area.value
            
            'loop through array
            Dim cel As Variant
            For Each cel In arr
            
                'if cell is not empty then
                If Len(Trim(cel)) > 0 Then
                    IsRangeEmpty = False
                    Exit Function
                End If

            Next cel
            
        Else    'cannot loop on array with one value
            
            'if cell is not empty then
            If Len(Trim(area.Value2)) > 0 Then
                IsRangeEmpty = False
                Exit Function
            End If
            
        End If

    Next area

    IsRangeEmpty = True

End Function

Example of how to use it:

Sub Test()
    Debug.Print IsRangeEmpty(Range("A38:P38"))
End Sub

If Range("A38:P38") is empty, it would print True in the Immediate Window; otherwise it'd print False.

IsEmpty returns True if the variable is uninitialized, or is explicitly set to Empty; otherwise, it returns False. False is always returned if expression contains more than one variable. IsEmpty only returns meaningful information for variants. (https://msdn.microsoft.com/en-us/library/office/gg264227.aspx) . So you must check every cell in range separately:

    Dim thisColumn as Byte, thisRow as Byte

    For thisColumn = 1 To 5
        For ThisRow = 1 To 6
             If IsEmpty(Cells(thisRow, thisColumn)) = False Then
                 GoTo RangeIsNotEmpty
             End If
        Next thisRow
    Next thisColumn
    ...........
    RangeIsNotEmpty: 

Of course here are more code than in solution with CountA function which count not empty cells, but GoTo can interupt loops if at least one not empty cell is found and do your code faster especially if range is large and you need to detect this case. Also this code for me is easier to understand what it is doing, than with Excel CountA function which is not VBA function.

Answer 4

Dim M As Range

    Set M = Selection

If application.CountIf(M, "<>0") < 2 Then
    MsgBox "Nothing selected, please select first BOM or Next BOM"
Else

'Your code here

End If

From experience I just learned you could do:

If Selection.Rows.Count < 2 
Then End If`

Clarification to be provided a bit later (right now I'm working)

Answer 5

Dim cel As Range, hasNoData As Boolean

    hasNoData = True
    For Each cel In Selection
        hasNoData = hasNoData And IsEmpty(cel)
    Next

This will return True if no cells in Selection contains any data. For a specific range, just substitute RANGE(...) for Selection.

Answer 6

Another possible solution. Count empty cells and subtract that value from the total number of cells

Sub Emptys()

Dim r As range
Dim totalCells As Integer

'My range To check'
Set r = ActiveSheet.range("A1:B5")

'Check for filled cells'
totalCells = r.Count- WorksheetFunction.CountBlank(r)


If totalCells = 0 Then
    MsgBox "Range is empty"
Else
    MsgBox "Range is not empty"
End If

End Sub

Answer 7

This just a slight addition to @TomM's answer/ A simple function to check if your Selection's cells are empty

Public Function CheckIfSelectionIsEmpty() As Boolean
   Dim emptySelection As Boolean:emptySelection=True
   Dim cell As Range
   For Each cell In Selection
       emptySelection = emptySelection And isEmpty(cell)
       If emptySelection = False Then
          Exit For
       End If
   Next
   CheckIfSelectionIsEmpty = emptySelection
End Function

Answer 8

This single line works better imho:

Application.Evaluate("SUMPRODUCT(--(E10:E14<>""""))=0")

in this case, it evaluates if range E10:E14 is empty.
