You can call .as_dict() on a row object inside an iteration through .render(). Here is a one-liner to replace all your code:
json.dumps(dict(data=[{k: v for sub_row in row.as_dict().values() for (k, v) in sub_row.iteritems()} for row in persons.render()])) The list comprehension iterates through persons.render(), which yields a Row object for each record (with the represent functions applied to each field). For each Row object, there is then a dictionary comprehension with two "for" clauses -- the first converts the Row to a nested dict via .as_dict and then uses .values() to extract the two nested dicts into a list containing the two dicts, and the second then calls .iteritems() on each of the dicts in order to generate a new dictionary. Note, you still have a problem -- you have two fields with the same name (i.e., "name"), so in the combined dictionary, the second will overwrite the first.
