if cell is not empty excel vba code example

Example 1: excel check if cell not empty

IF(A1<>"","Not empty","Empty")

Example 2: excel vba how to check if a worksheet cell is empty

'VBA to check if cell A1 is blank.

'The best way:
MsgBox IsEmpty([A1])
'But if a formula that returns a zero-length string is in A1, 
'IsEmpty() will return False.


'Another way:
MsgBox Len([A1]) = 0
'Len() will report 0 if A1 contains a formula that returns a
'zero-length string or is completely empty.

'But IsEmpty() is usually better because Len() will throw an
'error if there is an error value in the cell. IsEmpty() on the 
'other hand will just gracefully report False.

'The worksheet functions COUNT() and COUNTA() can also be utilized.
'But these require a call through the boundary between VBA and 
'Excel, which can be slow if done within a loop.
