Hello Guys,

=IF(AND(CELL("format",A2)="D4",
CELL("format",B2)="D4",
CELL("format",C2)="D4",
CELL("format",D2)="D4"),
"is in DATE Format",)

above formula is to check if all values in A2 to D4 are in date.
my boss challenged me to simplify above formula.

Just tested again the Array Formula for you ...

And it does work ...

As an alternative ... a simple UDF can also perforrn the task ...

Code:
``````Function CountDates(rng As Range) As Long
Dim c As Range
Dim x As Long
For Each c In rng
If IsDate(c.Value) = True Then x = x + 1
Next c
CountDates = x
End Function``````

P.S. For your info the Cell function does not accept an Array ...

You are welcome ...

Excel contains over 450 functions, with more added every year. That’s a huge number, so where should you start? Right here with this bundle.
