Data Scrapers are tools or programs used to extract data from websites. These tools automate the process of accessing web pages, retrieving the desired information, and storing it in a structured format such as CSV, JSON, or a database. Data scrapers can vary in complexity, from simple scripts that extract data from static web pages to advanced applications that handle dynamic content, handle CAPTCHAs, and respect robots.txt files. They are widely used in industries like e-commerce, finance, and research for tasks such as price monitoring, market analysis, and data aggregation. Effective data scrapers are designed to be efficient, reliable, and compliant with legal and ethical standards.
