importing tasks/lists from wunderlist into todoist

        return self._api_call('addProject', {'name': list_name})['id']

    def add_task(self, list_id, task_name):

def create_parser():
    parser = ArgumentParser()
    parser.add_argument('wunderlist_dump_json')
    parser.add_argument('todoist_email')

    return parser

if __name__ == '__main__':
    parser = create_parser()
    args = parser.parse_args()
    todoist_api = TodoistAPI(args.todoist_email, args.todoist_password)

    with open(args.wunderlist_dump_json) as f:
        j = json.load(f)
        lists = {}
        for l in j['lists']:
            lists[l['id']] = todoist_api.add_list(l['title'])
        lists['inbox'] = todoist_api.add_list('inbox')
        for t in j['tasks']:
            todoist_api.add_task(lists[t['list_id']], t['title'])

Works for me, the only thing I changed was to not import completed tasks from Wunderlist. That might be what @cjsnet was seeing too where he mentioned everything was going into the "inbox".

for t in j['tasks']:
    if 'completed_at' not in t:
        todoist_api.add_task(lists[t['list_id']], t['title'])

Works well as it is for me.
Just need to edit the json file from Wunderlist because of text encoding. Special characters in French are not supported by the script (for example: à).
Otherwise, perfect, thanks a lot kbl!

Does not work for me. All I get is:

Traceback (most recent call last): File "import.py", line 54, in <module> for l in j['lists']: KeyError: 'lists'

Any chance of checking on it kbl?

I have got the same problem....

Please kbl :)

Thanks in advance

@kbl

I've updated the gist so that it fixes the issues mentioned above. It's got to do with some changes in the Wunderlist JSON structure :P

Please update the original gist with my revision 👍

I've made some more mods to this, to allow completed tasks to be marked as completed in todoist, as well as migrate over all notes:

Thanks @duellsy,

Did you also incorporate @glnarayanan's fixes? His post is just above your last post.
If you did then your script is the latest, incorporating: KBL, your, & glnarayanan's work.

@duellsy,

I tried yours, got it going but it doesn't seem to have brought notes & sub-tasks along with it, completed task are all there I think, I can show you the output of my terminal session?

Marvelous, thanks!!!

I installed python and run the command in terminal and I got this:

Calling url https://todoist.com/API/login?password=%5B234234246645%5D&email=%5Bmyemailaddress%40gmail.com%5D
Traceback (most recent call last):
  File "import.py", line 62, in <module>
    todoist_api = TodoistAPI(args.todoist_email, args.todoist_password)
  File "import.py", line 16, in __init__
    self.token = self._api_call('login', {'email': email, 'password': password}, add_token=False)['token']
  File "import.py", line 28, in _api_call
    raise Exception('Call finished with error! %s' % return_value)
Exception: Call finished with error! LOGIN_ERROR

The login info is correct I typed it as you advised:
python import.py [wunderlist_dump.json] [wrote my email here] [wrote my password here]

Is it required to type the email and password somewhere inside .py file as well? Please advice what am I doing wrong?
