SharePoint calculated column formatting a date that is null

SharePoint calculated column formatting a date that is null

A few weeks ago one of my blog readers sent me a question regarding SharePoint calculated columns. He was trying to format a date column and it was working fine as long as the date wasn’t blank, or null. However when the date was null, he was getting some unexpected results.

I thought I would share the solution here on my blog in case anyone else runs into a similar problem. Following is the original question I received:

I was hoping you could help me with a calculated column condition. I have a Project list, and using calculated column to return the start and delivery dates to show “MMMM YYYYY” so if a delivery date is set to 6/30/2015 it’s displayed as “June 2015”. I created a new column called “New Delivery Date” to record if a project is behind schedule we will keep the Planned Delivery date is missed we still have it on record how far it’s behind.

The problem I have is the calculated column for New Delivery Date is returning “December 1899” since the column its referring to is blank. I would like to create an IF statement that says “IF New Delivery Date = date return MMMM YYYY if not, show as blank.” Could you assist with this?

After a couple emails back and forth to get more info and to determine the name of the column that the calculated column is referring to (which is New Completion Date), I came up with the following formula, and the reader verified that it worked:

=IF(ISBLANK([New Completion Date]),””,TEXT([New Completion Date],”MMMM YYYY”))

Basically what the formula is saying if you break it down into parts is this:

  • Tried both with 2010 and it would not work in my calculated field formula, kept getting error with;

    =IF(ISBLANK([CS Suspense Date]),””,TEXT([CS Suspense Date],”dd MMM yy”))


    =IF([CS Suspense Date],TEXT([CS Suspense Date],”dd MMM yy”),”no date”)

    • That is strange indeed. The syntax definitely looks to be correct. I’d make sure that the quotes are not the “fancy” quotes (which you sometimes get when you copy/paste from the web), and replace them with “straight” quotes if that is the case.

  • I’ve been doing something similar in Sharepoint to leave blank a total field if all of the summed fields are blank. The output is a currancy field and the formula is =IF(AND(ISBLANK(Comm2015),ISBLANK(Fee2015)),””,(Comm2015+Fee2015)).

    Sharepoint is fine with that, but when I look at the results in Access 2013, it shows the calculated fields as #Error. Have you by chance seen that before?
