Since updating to v1.4.06, the "Minimal" JSON export does not correctly wrap quotation marks around strings, making the resulting ".json" files invalid JSON.
Example snippet -
{bones:[{name:root},{name:bone1,parent:root,length:43.85,x:10.79,y:76.97,rotation:-167.99},{name:bone2,parent:bone1,length:31.43,x:-0.62,y:0.5,rotation:27.81},{name:bone3,parent:bone1... etc
Adding quotes manually is... tedious at best.
