Just load the data you want to parse inside a worker, and perform the
parsing there. Computationally-expensive work is exactly something Web
Workers are meant for.

There's no need to serialize to JSON before sending data to a worker;
there's nothing that JSON can represent that postMessage can't post
directly. Just postMessage the object itself.
