Posting links to information on third party websites does not help when, at some time in the future, that information is removed. The thread then becomes useless for anyone else with the same problem. And is a 1 MB file really necessary? Please attach that document here, or better still only the part that really matters, using "File attachments". Have you looked at the information here in Resources > Building Blocks?

[Edit]

(For anyone else thinking of answering: don't bother downloading the file, notes of the contents follow.)

I've downloaded that file. All it is is a spreadsheet of values, a column of times, three columns of currents, and two pairs presumably humidity and temperature. There are more than 22,000 rows altogether. 

You cannot compute power knowing current alone. Even if you know the voltage, from that data you cannot compute real power (watts), only apparent power (volt-amperes) unless you know the power factor of your load. Can you explain a little more clearly and fully what you are trying to do, and what you have attempted?
