File format or file extension is not valid, Verify that the file is not corrupted - python

Question

Problem:

• I've written a code that first creates a file and saves the data to the same file.
• After opening the file an error shows up File Format or file extension is not valid, Verify that the file is not corrupted.

Code:

from selenium import webdriver
import time
from bs4 import BeautifulSoup as Soup
from urllib.request import urlopen
import datetime as dt
import csv
import pandas as pd

driver = webdriver.Firefox(executable_path='C://Downloads//webdrivers//geckodriver.exe')


c1 = 'amazon_data_' + dt.datetime.now().strftime("%d_%b_%y_%I_%M_%p")

# d = open(str(c1) + '.csv', 'x', encoding='utf-8')
d = open(str(c1) + '.xlsx', 'x', encoding='utf-8')

for c in range(1):

    a = f'https://www.flipkart.com/search?q=sony+headphones&as=on&as-show=on&otracker=AS_Query_HistoryAutoSuggest_1_4_na_na_na&otracker1=AS_Query_HistoryAutoSuggest_1_4_na_na_na&as-pos=1&as-type=HISTORY&suggestionId=sony+headphones&requestId=ad797917-16ae-401e-98df-1c79a43d40c3&as-backfill=on&page={c}'

    '''
    request_response = requests.head(a)

    status_code = request_response.status_code
    if status_code == 200:
        print(True)

    else:
        print(False)
        '''
    driver.get(a)

    # time.sleep(1)

    page_soup = Soup(urlopen(a), 'html5lib')

    container = page_soup.find_all('div', {'class': '_4ddWXP'})
    for containers in container:
        find_url = containers.find('a')['href']
        new_url = 'https://www.flipkart.com' + find_url

        fetch = driver.get(new_url)
        # time.sleep(1)
        page_source = driver.page_source
        page_soup = Soup(page_source, 'html.parser')
        for data in page_soup:

            try:
                product_name = data.find('span', {'class': 'B_NuCI'}).text.strip()
                price = data.find('div', {'class': "_30jeq3 _16Jk6d"}).text.strip()
                current_url = new_url
            except:
                print('Not Available')
            # print(product_name, '\n', price, '\n', current_url, '\n')
            d.write(product_name + price + current_url + '\n')
                

Error I got

1. While trying to save the output data in .xlsx format, It saves the file properly. But while opening it, an error pops out:- The file format of the extension is not valid, verify the file is not corrupted and the file extension matches the format of the file.

Things I tried

When I try to write the output data with .csv it saves properly. But while opening the file, data has some special characters and data is not written in single cell.

Uploading an Image for better Understanding

• Below I'm providing url of an image which has excel output that I got while fetching data from above script and saving it to .csv file.

Things I want

1. I want to save this date in .xlsx format with relevant following 3
   headers :- product_name, price, URL.
2. I want all the special characters to be removed so that I get the clean output while writing the data in .xlsx format.

Answer 1

I see few problems:

1. using open(), write() you can't create xlsx because it has to be file .xml compressed with zip

2. some data has , which normally is used as separator for columns and you should put data in " " to create columns correctly. Better use module csv or pandas and it will use " " automatically. And this can be your main problem.

3. you mix selenium with beautifulsoup and sometimes you make mess.

4. you use for data in page_soup so you get all children on page and run the same code for these elements but you should get values directly from page_soup

I would put all data on list - every item as sublist - and later I would convert it to pandas.DataFrame and save it using to_csv() or to_excel()

I would even use selenium to search element (ie. find_elements_by_xpath) instead of beautifulsoup but I skiped this idea in code.

from selenium import webdriver
import time
from bs4 import BeautifulSoup as BS
import datetime as dt
import pandas as pd

# - before loop -

all_rows = []

#driver = webdriver.Firefox(executable_path='C:\\Downloads\\webdrivers\\geckodriver.exe')
driver = webdriver.Firefox()  # I have `geckodriver` in folder `/home/furas/bin` and I don't have to set `executable_path`

# - loop - 

for page in range(1):  # range(10)`
    print('--- page:', page, '---')
    
    url = f'https://www.flipkart.com/search?q=sony+headphones&as=on&as-show=on&otracker=AS_Query_HistoryAutoSuggest_1_4_na_na_na&otracker1=AS_Query_HistoryAutoSuggest_1_4_na_na_na&as-pos=1&as-type=HISTORY&suggestionId=sony+headphones&requestId=ad797917-16ae-401e-98df-1c79a43d40c3&as-backfill=on&page={page}'

    driver.get(url)
    time.sleep(3)  

    soup = BS(driver.page_source, 'html5lib')

    all_containers = soup.find_all('div', {'class': '_4ddWXP'})
    
    for container in all_containers:
        find_url = container.find('a')['href']
        print('find_url:', find_url)
        item_url = 'https://www.flipkart.com' + find_url

        driver.get(item_url)
        time.sleep(3)
        
        item_soup = BS(driver.page_source, 'html.parser')
        
        try:
            product_name = item_soup.find('span', {'class': 'B_NuCI'}).text.strip()
            price = item_soup.find('div', {'class': "_30jeq3 _16Jk6d"}).text.strip()

            print('product_name:', product_name)
            print('price:', price)
            print('item_url:', item_url)
            print('---')
            
            row = [product_name, price, item_url]
            all_rows.append(row)
                
        except Exception as ex:
            print('Not Available:', ex)
            print('---')
