Just skimmed through the announcement found here:
http://www.insidegadgets.com/2012/08/13/standalone-temperaturevoltage-logger-updated-to-v1-1/
which says, in the last lines:
It will generate a file name based on the current date and time and show you the data being transferred.
So I don't see the logger program injecting data directly into any app, just writing data into a file (like the csv approach others have told you about).
Maybe with Visual Basic one could write a serial-to-excel program that uses excel api to open a spreadsheet and control it (just guessing). Maybe Openoffice has some similar capability too (don't know OOo Basic that well, either).
