Integration in Excel

I have downloaded the instantaneous flow (l/sec) every minute from the historical log file of Wonderware HMI.

I now want to see if it is possible to totalize the values, so I can get the average flow per day or flow per hour.

Technically, I know that we have to use the "Integral" function. I have no clue to program this.


Could some please throw some light on this.

Would very much appreciate you intervention.

I have attached the txt file for review.


Thank you.
