Hi,
I worked on similar projects, Im an expert when it comes to betfair.
I suggest that the project will be a C# exe that you run and it generates the excel file you need.
Here I suggest something that you will never find somewhere else.
You can have ALL the data you need from betfair, without the need to have the paid appkey.
I have developped my own betfair API that doesnt rely on the paid appkey.
Of course you still need a betfair account, but no need for 299$ fees.
I can garantee you the best solution. Satisfaction garantee or no money asked.
Thank you in advance.
