We don't need a new format which works for machines as well as for humans, because there are are tons of existing ones. You have CSV or TSV for wide support; JSONlines if you want very easy edit-ability and structure; and if those don't work for some reason, pretty much any other delimiter/escape would work better (example: newline for records, "^^" for fields, "^"-style character escaping; or JS-style "\"-escaping with field separator being "\N")
