What is the formula for a time sheet adding work hours in military time.
Example Cell A1=8:00 and Cell A2=12:00. My formula =Mod(A2-A1,1) will return the correct answer, but the problem is that this formula will return the answer of 16 if nothing is put in cell A2. I want no answer if nothing is in cell A2.

When did Power Query debut in Excel?
Although it was an add-in in Excel 2010 & Excel 2013, Power Query became a part of Excel in 2016, in Data, Get & Transform Data.

=IF(A2="","",MOD(A2-A1,1))
