Websites that show lists of information generally do it by querying a database and displaying the data in a user friendly manner. A web scraper reverses this process by taking unstructured sites and turning them back into an organized database. This data can then be exported to a database or a spreadsheet file, such as CSV or Excel.
Some of the uses for web scraping include:
Build supplier and manufacturer price databases.
Find best offers by comparing prices from multiple websites.
Discover trends and statistical information for academic and scientific research.
Extract information from governmental websites for data journalism.
Aggregate information from several websites to be shown on a single website.
Build contact information databases from real estate websites.
Analyze forums and social media sites to discover trends and patterns.
Apply custom sorts and filters to data shown on any website.
Extract training data for machine learning.
