parse_csv.py

#!/usr/bin/env python3

from enum import Enum, unique
import sys, json

@unique
class Columns(Enum):
    FOLDERNAME=0
    FAVORITE=1
    TYPE=2
    NAME=3
    NOTES=4
    FIELDS=5
    LOGIN_URI=6
    LOGIN_USERNAME=7
    LOGIN_PASSWORD=8
    LOGIN_TOTP=9


def get_cred_from_line(line):
    result = {}
    for name, member in Columns.__members__.items():
        result[name.lower()] = line[member.value]
    return result

result = { 'data': [] }
with open(sys.argv[1], 'r') as f:
    next(f)  # skip header
    result['data'] = [ get_cred_from_line(x.split(',')) for x in [ y.strip() for y in f.readlines() ]]

print(json.dumps(result, indent=4))
