Hi Ankit,

You can import the user details using a csv file or an excel file. When I tried importing users the last day, it was taking an unusual amount of time. So I wrote a simple python function to create users and assign correct permissions. To set the correct permissions, find the field names of the permissions you need to apply while creating the users. These field name will be like 'sel_groups_1_9_10'. Just as the name suggests, those numbers are the values which the field can take. So create a list of dictionaries, with the users and their details. For example

users = [('name': 'Test', 'login': 'test@test.com', 'email': 'test@test.com', 'password': '', 'sel_groups_1_9_10': 1), ('name': 'Employee', 'login': 'employee')]

Now iterate over this list of dictionaries and create users based on these values.

for each in list:

    self.env['res.users'].create({'name': each['name'], 'login': each['email'], 'password': '',
                                        'sel_groups_11_12': each['sel_groups_11_12'], 'sel_groups_17_18': each['sel_groups_17_18']})

This will create users with the corresponding values given in the list
