You might talk to Gary Pitz about writing what you need. The Twinspires mobile site is importing into his program (At The Races) well enough. For the price of an annual subscription ($100 per year), he might program it (if it doesn't exist already) so that data from requested tracks are exported to text or CSV files in a dedicated folder, where your Excel program can access and convert them to extract what you want.
The good part about having it done through ATR is that if one tote source stops working, you can use another which will produce the same file, until Gary fixes the program to work with the non-working source. The downside, of course, is that it isn't free.
You can find ATR at
http://htr2.com/atr/atrpro_dnl.htm . Download the program (30 day trial) and then fetch the updated executable just below it and install it over the original. I suggest contacting Gary at the email listed on the page before purchasing. If what's needed is simple to program, he might include it with the subscription; otherwise, his programming fees are very reasonable.
