Thanks Bill, I took a look the the convert/addon code and realized it was handling the general case which is overkill for girds.
Writing general parsers that scale well in J is hard. I've seen some neat dyadic ;: cases and sometimes cut can come very close. I think JSON data is important enough to come up with a something that handles the general case for large (>5mb) arguments quickly.
