Calculated Column if any Column is Blank

jamescosten If you need to show TRUE or Yes if any of the columns is blank, use formula like: 

=IF(OR(ISBLANK([Column 1]),ISBLANK([Column 2]),ISBLANK([Column 3])),"Yes","No")

If you need to show TRUE or Yes if all columns are blank, use formula like: 

=IF(AND(ISBLANK([Column 1]),ISBLANK([Column 2]),ISBLANK([Column 3])),"Yes","No")

Note:

1. Sometimes comma( , ) does not work in formula (it is based on language or regional settings of your SharePoint site). So in that case use semicolon( ; ) instead of comma( , ).
2. Use correct display name of your SharePoint columns in above formula.
3. Wrap column names inside [] if your column name has space in it. For example: [My Column Name].
