Question about data-driven animation

Ok, so After Effects is able to use JSON files to control animations. Can the data from the JSON (or Excel) file be accessed and updated after exporting with Lottie?

I’m going to attempt to explain an example, so please bear with me:
Say there is a website that has the real-time score from a baseball game. I have an After Effects project with a data-driven scoreboard animation. I want to export from Lottie and still be able to access data-driven expressions, like sourceText, and update them automatically from the real-time source. Is this possible through Lottie and Javascript? Or a clever workaround?


I just found this article and I’m hoping this is heading in the right direction
