Converting data from .csv file to .json - Python


I need to convert data from my csv file to the one i am gonna use which is .js.

Lp.;Name;Surname;Desc;Unit;Comment
1;Jan;Makowski;Inf;km;
2;Anna;Nowak;Pts;km;Brak reakcji

If you can see column 'comment' does not always have record and I need to keep it that way. Also between data there is amount of tabs I need to set as well.

enter image description here

I've a file,i am working on right now but It show's me data in row like :

[{"Lp.;Name;Surname;Desc;Unit;Comment": "1;Jan;Makowski;Inf;km;"}, {"Lp.;Name;Surname;Desc;Unit;Comment": "2;Anna;Nowak;Pts;km;Brak reakcji"...]

I am new to python and I have no idea how to define what I need to get.

@@ Edit I managed to do that...

import json
import csv

# Deklaracja danych
fieldnames = ("Lp.", "Name", "Surname", "Desc", "Unit", "Comment")

#  Otwieranie plików
with open('file.csv', 'r', encoding = "utf8") as csvfile:
    reader = csv.DictReader(csvfile) # ,fieldnames)
    rows = list(reader)

# Zamykamy plik
csvfile.close()

# Tworzymy plik z danych
with open('file.json', 'w', encoding = "utf8") as jsonfile:
    json.dump(rows,jsonfile)
    # jsonfile.write(s.replace(';', '/t'))
# Zamykamy plik
csvfile.close()

Solution

  • I think this is your answer, this may not be the best way to do it, but it can gives you the result.

    import csv
    import json
    with open('file.csv', 'r') as f:
        reader = csv.reader(f, delimiter=';')
        data_list = list()
        for row in reader:
            data_list.append(row)
    data = [dict(zip(data_list[0],row)) for row in data_list]
    data.pop(0)
    s = json.dumps(data)
    print (s)
    

    output:

    [{"Comment": "", "Surname": "Makowski", "Name": "Jan", "Lp.": "1", "Unit": "km", "Desc": "Inf"}, {"Comment": "Brak reakcji", "Surname": "Nowak", "Name": "Anna", "Lp.": "2", "Unit": "km", "Desc": "Pts"}]
