Python script to split starred.json into smaller junks to make them usable for alternatives. Sometimes trying to import starred.json files with more than 50mb or even less fail. -> split it and it should work.

split_starred_json.py

# run script within a directory where your exported starred.json file is available

import json
from copy import deepcopy

json_data = open('starred.json')
data = json.load(json_data)

default = deepcopy(data)
default['items'] = []

l = len(data['items'])
ran = range(l)
steps = ran[1000::1000]

data_split = deepcopy(default)
count = 0

for i in ran:
  data_split['items'].append(data['items'][i])
  if i in steps or i == l-1:
    name = 'starred_split_' + str(count) + '.json'
    with open(name, 'w') as outfile:
      json.dump(data_split, outfile)
    data_split = deepcopy(default)
    count = count   + 1

print 'now you can import your splitted files into your new reader. One by one.'
