Hi
If you are referring to backing and laying directly from an Excel workbook using VBA code, I’m afraid I can’t help you.
But if you want to activate a trigger action according to some data in an Excel sheet, please see the attached example trigger.
It will back the Home team in a Match Odds market if the value of cell A1 on DemoSheet is greater than 5
You can make similar triggers and conditions for other trigger actions e.g. cancel all if the value of cell A5 is "Y" etc.
