How does BA/EXCEL link work?

[thunderfoot]

I can understand that BA has the capability to download data to EXCEL, I even understand the capability of EXCEL to 'download' data from websites using Data/Import External Data/New Web Query, but what I don't understand is how, in effect, EXCEL is 'uploading' data to Betfair albeit being via BA.

Any one know how this is working?
Could data be 'uploaded' from EXCEL to other websites i.e. Betdaq?

Also, where can we find a kind of instruction manual or help section on how to write triggers on Exell and how it links to BA
