Web Info Extractors (commonly known as web scrapers, data extractors, or web harvesters) are automated software tools designed to automatically identify, gather, and organize information from websites. They transform raw, unstructured HTML code from the internet into clean, structured data formats like Excel spreadsheets, CSV files, JSON, or databases. Core Types of Web Extractors
Depending on technical complexity and the specific use case, extractors generally fall into three categories:
Browser Extensions: Simple point-and-click tools (e.g., Web Scraper) built for quick, small-scale data tasks.
Local Software Platforms: No-code/low-code applications (e.g., Octoparse, ParseHub) that handle highly complex scraping rules locally.
Programming Libraries: Developer-centric code scripts using packages like Beautiful Soup or Selenium in Python to extract data at an enterprise scale. How Web Info Extractors Work
The data extraction pipeline follows a strict, sequential four-step process:
