Blood Pressure from Excel spreadsheet to CSV to FIT help required.

I have a lot of historical blood pressure data that I'd like to Connect.  It's in an Excel spreadsheet, but I don't know what format it should be in wrt a CSV file, so I can convert with the CSV to FIT utility.  I've done it OK for my weight/body scales as I found the correct CSV format & I wrote a utility to convert my data into that format which then successfully converted to FIT.   So, if I can get hold of a sample of a blood pressure CSV file, with Systolic.Diastolic (& pulse-rate), preferably with more than 1 reading, I can probably write a utility to convert into the correct CSV format.  Any help most welcome.
