    Adding time in excel.

    Hello

    Im trying to add call time that I pull for my sales team. The format it comes out in excel is HH:MM:SS if they had a total talk time of more then an hour. If they only taked for says 45 minutes it comes in like this :45:00.

    The problem I am having is that I can sum everything that is formated comes in as 00:00:00 but not if its :00:00. I put an example below. It sums the first two but not the second to. So far the only fix I have is manually putting an a 0 in front. Which really is time consuming for the volume I work with. Any suggestions on how to get it to sum or convert to a 00:00:00 format.



    Rep 1 1:00:00
    Rep 2 1:23:51
    Rep 3 :07:51
    Rep 4 :40:20
    Sum 2:23:51

    If you have data in A1:A10 try this formula to sum

    =SUMPRODUCT((0&A1:A10)+0)

    format result cell as [h]:mm:ss

    Wow, thanks so much that worked perfect. The more I work with excel I realize there is not always a magic formula but a formulas altered to the way you need the to work. Can you explain how this foruma works? I have never used SUMproduct before.

    Re: Adding time in excel.

    The formula is just concatenating 0 to the front of the times, i.e. 0&A1:A5 - that won't alter the value of a valid time or a blank cell but it makes a text string like :40:20 look like a valid time value, i.e. 0:40:20......but that's still a text string so the +0 "co-erces" the text string that looks like a time into a real time.

    All we need to do then is to sum the results so

    =SUM((0&A1:A10)+0)

    will work......but that's is an "array formula" that needs to be entered with CTRL+SHIFT+ENTER. Using SUMPRODUCT instead of SUM means you don't need that key combination....
