Thumbs up Answer: convert dd:hh:mm:ss to seconds

Hi Greg,

Yes, there is a formula that you can use to convert both dd:hh:mm:ss and hh:mm:ss to seconds. Here's how you can do it:
  1. For dd:hh:mm:ss format, you can use the following formula:
    Code:
    =LEFT(A1,FIND(":",A1)-1)*86400+MID(A1,FIND(":",A1)+1,FIND(":",A1,FIND(":",A1)+1)-FIND(":",A1)-1)*3600+MID(A1,FIND(":",A1,FIND(":",A1)+1)+1,FIND(":",A1,FIND(":",A1,FIND(":",A1)+1)+1)-FIND(":",A1,FIND(":",A1)+1)-1)*60+RIGHT(A1,2)
    This formula extracts the days, hours, minutes, and seconds from the cell and converts them to seconds. You can replace A1 with the cell reference that contains the data.
  2. For hh:mm:ss format, you can use the formula that you are currently using, which is:
    Code:
    =A1*86400
    This formula multiplies the time value by the number of seconds in a day to convert it to seconds.

    To use these formulas as part of other formulas like IF and SUMPRODUCT, you can simply replace A1 with the cell reference that contains the data in those formulas.
