Date Formatting

New Contributor

I have a series of cells with a vlookup formula which either returns a date (if the lookup table has a date) or a blank. This works fine. I am trying to pick up the value of that cell and return a code letter in another cell which will either be "Y" or "N" if the cell is blank or has a date in  it. The cell is formatted as a standard date field.

I have tried ISBLANK, looked at the LEN of the cell but am having problems solving this issue. Any help gratefully received.

ISBLANK works only with the completely blank cells.

If the blank is returned by a formula, then you have to check whether the cell is blank or not using this formula:



Hope that helps

Thanks Haytham, but I am afraid it does not work. Although the cell appears to be blank, If I ask for the LEN(cell ref) I get "01/01/1900". I have tried using that in the formula, but that does not work either.

The lookup formula works perfectly to either display a date or a blank cell, but I need to identify if it is displaying a date then another cell gets to show a code letter.




Hi Ernie,


I can't figure out what exactly you're trying to do!

I understood that you have a date column contains dates and some blank cells, all returned by VLOOKUP.

And you want in another column to check whether the cell is blank or not.

So I have suggested this formula:



I don't know why you use the LEN function?

If can provide a sample worksheet attached here, that's would be better to figure out what is the problem.

As a comment, it looks like misprint is here

LEN(cell ref) I get "01/01/1900"

it shall be "00/01/1900" (if dd/mm/yyyy format), other words LEN(cell ref) returns 0.
