I have a column of data in Excel that is HH:MM:SS format, for example, 0:30:42 (thirty minutes forty-two seconds), When using the formula =SUM(b2:b3), I get zero value. If I do B2+B3 I get a result.


Is there another formula/function to add time values?

Can you AutoAverage in Excel?
There is a drop-down next to the AutoSum symbol. Open the drop-down to choose AVERAGE, COUNT, MAX, or MIN
I think this might help.

Also, check out this info from Microsoft.

And this is a deep summary of number formatting. This one lets you practice.
