And the question is to extract everything in json and write it to Nosql (MongoDB) (And there are only 5 columns)

The file, alas, in this form is not parsed in a logical way, so it cannot be divided into reasonable objects.
You can simply load line by line, through with open readline, adding id's.
How to work with PyMongo can be read in the documentation: https://pymongo.readthedocs.io/en/stable/
Let's assume that your data is in the file file.txt, and MongoDB is running on the same machine (locally), the script is extremely simple:
import pymongo
# Создаем клиент MongoDB
client = pymongo.MongoClient()
# Название БД
db = client['univercity']
# Название коллекции
collection = db['courseworks']
# Открываем файл
with open('file.txt') as file:
# Читаем строки из файла в переменную
lines = [line.strip() for line in file.readlines()]
# Проходим по каждой строке
for line in lines:
# Делим строку на слова
words = line.split()
# Извлекаем столбцы
a, b, c, d, e = words[0], ' '.join(words[1:-3]), words[-3], words[-2], words[-1]
# Вставляем документ в базу Монго
collection.insert_one({
"type": a,
"text": b,
"lang": c,
"version": d,
"value": e
})
> use univercity
switched to db univercity
> db.courseworks.find()
{ "_id" : ObjectId("60b77e2c9fa82c54395b405e"), "type" : "КП", "text" : "Провайдер", "lang" : "Delphi", "version" : "7.0", "value" : "900+" }
{ "_id" : ObjectId("60b77e2c9fa82c54395b405f"), "type" : "Программа", "text" : "Программа для тестирования (версия 1)", "lang" : "Delphi", "version" : "7.0", "value" : "1000" }
{ "_id" : ObjectId("60b77e2c9fa82c54395b4060"), "type" : "Программа", "text" : "Программа для тестирования (версия 2)", "lang" : "Delphi", "version" : "7.0", "value" : "1400" }
You can break strings into their component parts using regular expressions.
Here, a partial version for the seed:
/(Delphi\s\S+)\s(\S+\+?)$/gm
where are the pair of Delphi XE and 2990+
The rest is self.
