My Spreadsheet is online through Google Drive. That way, I can access it from anywhere, link to it here and send the link to my vet for review.
It looks complicated, but isn't really. AMPS is the BG reading taken before the morning shot. Units is where you record the units you gave in that shot. the +1/+2/+3 type columns each stand for hours after the morning shot until you reach the PMPS, or evening shot reading. Again, there's a column for the units in the shot, and +1...columns for any readings taken after the evening shot.
Somewhere here, there's a link for how to set up the spreadsheet on Google Drive...I'm just not sure where that link is right now. If I can find it, I'll post it.
