What is the easiest way to check if a cell is a date in VBA?

---

You can use the IsDate function in VBA to check if a given cell is a date.

This function will return True if the value in a given cell is recognized as a date.

Otherwise, the function will return False.

Here is one common way to use this function in practice:

Sub CheckDate()
    
Dim i As Integer

For i = 1 To 9
    
    If IsDate(Range("A" & i)) = True Then
        Range("B" & i) = "Is a Date"
    Else
        Range("B" & i) = "Is Not a Date"
    End If
Next i
    
End Sub

This particular macro will check if each cell in the range A1:A9 is a date.

If a cell is a date, then “Is a Date” will be returned in the corresponding cell in the range B1:B9.

If a cell is not a date, then “Is Not a Date” will be returned instead.

The following example shows how to use this syntax in practice.

Example: How to Use IsDate in VBA

Suppose we have the following column of values in Excel:

Suppose we would like to check if each cell in column A is a date.

We can create the following macro to do so:

Sub CheckDate()
    
Dim i As Integer

For i = 1 To 9
    
    If IsDate(Range("A" & i)) = True Then
        Range("B" & i) = "Is a Date"
    Else
        Range("B" & i) = "Is Not a Date"
    End If
Next i
    
End Sub

When we run this macro, we receive the following output:

Note that we chose to return either “Is a Date” or “Is Not a Date” but you can return whatever you would like using the If Else statement.
