- Parsing and Structuring Data - Raw HTML data is parsed using tools like BeautifulSoup, Selenium, or Scrapy to extract pricing and product information.

Challenges of Scraping Grocery Apps
1. Anti-Scraping Techniques
CAPTCHAs, bot detection techniques, and IP blocking are implemented in many grocery apps to avoid automated scraping.
2. Dynamic Content Loading
Most grocery apps are JavaScript-based frameworks. Therefore, contents are not extractable without using Selenium or headless browsers.
3. Data Inconsistencies
Each platform uses different naming identifiers and product descriptions, thus complicating direct price comparisons.
4. Frequent UI Changes
A grocery application that updates its UI regularly means its scrapers must also be regularly updated to function.
5. Legal and Ethical Considerations
Keeping in mind the terms of service of websites and data privacy policies, a breach may result in severe legal consequences.
Best Practices for Scraping Grocery Apps
- Rotating Proxies - Helps in decreasing the chances of IP bans and detection.
- Headless Browsers - Either Selenium or Puppeteer would do the job of maintaining a seamless interaction with JavaScript-heavy pages.
- Robots.txt - In every case, a website's robots.txt file should be subject to scraping policies.
- Data de-duplication - Remove involved duplicate entries through competent data-cleansing methods.
- Proper Scheduling of Scraping - Carrying out scraping during off-peak hours helps to avoid congestion on the server.
