Hi,

You can make a conditional formatting on your date column and find the
result in color for example:
if the date is before expiry date no color
in expiry date the color could be yellow
after expiry date the color could be red

Thanks,

if your date is in cell A1, put the following formula in cell B1:

=IF(A1-TODAY()<31,"Warning","OK")

Note that with this formula you'll get "Warning" also when certificates have
already expired. You could improve the process by having:

=IF(A1<TODAY(),"Expired",IF(A1-TODAY()<31,"Warning","OK"))

I have an excel document with dates of when offshore certificates expire. I'd
like a column that would say "Warning" when it's 30 days before the
certificate expires, unitl a new date is entered then it would say "OK".
