Hi voidstate, great to see you throw your 2 cents in!
JSON is great for human readability, but I don't know that you will be able to fit an epic squad in JSON in a reasonably sized QR code. But maybe a character limit of ~6 per pilot would alleviate this. Going to keep thinking about this...
It would be nice if the QR code contained all the JSON data, so the TO can scan the QR code at the event to directly read in the squad details.
