migration evernote to notion ( by python program :enex2notion)

I 've been used  evernote for a long time. but  I changed to notion recently. 

I tried to export data from  evernote to notion. The guide which is proposed by notion team is not good.  But I found 'enex2notion' tool  by googling. It it very effective for me although  some installation step is not simple for me.

I shared it for another users.  

My pc is mac. 

ref: https://github.com/vzhd1701/enex2notion

Step 

1. install enex2notion

  -  you can refer on above ref site. Don't give it up , this app is compensate for your install try.

2. export notebooks from evernote app.

2.5  get  auth_v2 key from your browser

  -  open notion with web browser and login 

  -  find cookie ( token_v2)  in browser. You need  token to upload to notion 

3 run enex2notion with notebook file (*.enex)

 - program will upload  pages one by one  ( Upload speed is not fast.)

 - some pages are fail to uploading. ( You must copy these pages by manual )

 - You can check progress on your notion app.

 enex2notion --token <TOKEN from 2.5 step> "mynotebook.enex"  ## do not include letter "<", ">"

4. Check pages which are uploaded. 

OrderedDict. ( in Python)

func: Dictionary remembers added order of items.

Ref : https://docs.python.org/3/library/collections.html

Usecase  sample : convert number to roman numerals.

import string

from collections import OrderedDict

def to_roman(num):

maps = OrderedDict([('M', 1000), ('CM', 900), ('D', 500),

('CD', 400), ('C', 100), ('XC', 90), ('L', 50), ('XL', 40),

('X', 10), ('IX', 9), ('V', 5), ('IV', 4), ('I', 1)])

res = ''

for k, v in maps.items():

while num >= v:

print(f' {num}, {v}')

res += k

num -= v

return res

print(1988)

print(to_roman(1988))

### output #####

1988 1988, 1000 988, 900 88, 50 38, 10 28, 10 18, 10 8, 5 3, 1 2, 1 1, 1 MCMLXXXVIII

' select all "mynode" from root node recursively ( ref. xml path grammar in detail)

' root node에서 mynode 모두 선택하기 추가적인 부분은 xml path 문법을 참고

Set nodeList = xmlObj.SelectNodes("//mynode")

for index to nodeList.Length -1
