What is a Web Scraper?
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.
