Error to convert JSON file into a QR-Code

Question

I'm trying to convert a json file into a qr code using pyqrcode

import tkinter as tk
from tkinter import filedialog
import json
import pyqrcode as qrcode

root= tk.Tk()
root.title('Convertitore CSV in JSON')

canvas1 = tk.Canvas(root, width = 300, height = 300, bg = 'lightsteelblue2', relief = 'raised')
canvas1.pack()

label1 = tk.Label(root, text='Tool Conversione File', bg = 'lightsteelblue2')
label1.config(font=('helvetica', 20))
canvas1.create_window(150, 60, window=label1)

def json_to_qrcode(jsonFilePath2, imageFilePath):
    with open(jsonFilePath2, 'w', encoding='utf-8') as jsonf:
        jsonReader = json.load(jsonf)
         
        qr = qrcode.QRCode(version = 1, box_size = 15, border = 5)
        data = jsonReader
        qr.add_data(data)
        qr.make(fit = True)
        img = qr.make_image(fill = 'black', back_color = 'white')
        img.save('Dieta.png')
        
jsonFilePath2 = filedialog.askopenfilename()
imageFilePath = filedialog.asksaveasfilename(mode='w', defaultextension=".png")

browseButton_CSV = tk.Button(text="     Importa JSON File     ", command=json_to_qrcode(jsonFilePath2, imageFilePath), bg='green', fg='white', font=('helvetica', 12, 'bold'))
canvas1.create_window(150, 130, window=browseButton_CSV)

root.mainloop()

Here is an example of JSON file:

[
    {
        "Giorno": "Lunedi",
        "Tipologia": "Prima Colazione",
        "Alimento": "Fette biscottate",
        "Quantita": "3",
        "UDM": "fette",
        "Note": ""
    },
    {
        "Giorno": "Lunedi",
        "Tipologia": "Prima Colazione",
        "Alimento": "Latte",
        "Quantita": "200",
        "UDM": "g",
        "Note": ""
    }
]

When I try to run the code it gives to me this error: "TclError: bad option "-mode": must be -confirmoverwrite, -defaultextension, -filetypes, -initialdir, -initialfile, -parent, -title, or -typevariable"

How can I solve it? Thanks in advance.

Answer 1

Can you try with the below code. I think your problem should be resolved now.

please install pillow library. (pip install pillow)

issues

1. You are trying to pass wrong args for filedialog.asksaveasfilename() function.

2. you are using pyqrcode instead of qrcode. (you have written code regarding qrcode library)

    import tkinter as tk
    from tkinter import filedialog
    import json
    import qrcode
   
    root = tk.Tk()
    root.title('Convertitore CSV in JSON')
   
    canvas1 = tk.Canvas(root, width=300, height=300, bg='lightsteelblue2', relief='raised')
    canvas1.pack()
   
    label1 = tk.Label(root, text='Tool Conversione File', bg='lightsteelblue2')
    label1.config(font=('helvetica', 20))
    canvas1.create_window(150, 60, window=label1)
   
   
    def json_to_qrcode(jsonFilePath2, imageFilePath):
        with open(jsonFilePath2, 'r') as jsonf:
          jsonReader = json.load(jsonf)
   
          qr = qrcode.QRCode(version=1, box_size = 15, border = 5)
          data = jsonReader
          qr.add_data(data)
          qr.make(fit=True)
          img = qr.make_image(fill='black', back_color='white')
          img.save('Dieta.png')
   
   
   jsonFilePath2 = filedialog.askopenfilename()
   imageFilePath = filedialog.asksaveasfilename()
   
   browseButton_CSV = tk.Button(text="     Importa JSON File     ", 
   command=json_to_qrcode(jsonFilePath2, imageFilePath),
                             bg='green', fg='white', font=('helvetica', 12, 'bold'))
   canvas1.create_window(150, 130, window=browseButton_CSV)
   
   root.mainloop()
