What Is Web Scraping?
Web scraping is the process of automatically collecting data from websites using software tools or scripts.
Instead of copying and pasting information manually, web scraping tools fetch web pages, extract relevant data, and store it in a structured format.
Key Components of Web Scraping
- Target Website: The source of data
- Scraper Tool: Software or script used to extract data
- Parser: Extracts specific elements like text, images, or links
- Output Format: CSV, JSON, database, or API
Simple Example
Imagine you want product prices from an eCommerce site. A scraper can:
- Visit the website
- Locate product listings
- Extract price, name, and rating
- Save it in a spreadsheet
