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

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

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  gt  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    gt  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    gt  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  quot A38 P38 quot    End Sub  If Range  quot A38 P38 quot   is empty  it would print True in the Immediate Window  otherwise it d print False

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

This single line works better imho   Application Evaluate  SUMPRODUCT -- E10 E14 lt  gt        0     in this case  it evaluates if range E10 E14 is empty

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
