Free and easy to use web data extraction tool for everyone.
With a simple point-and-click interface, the ability to extract thousands of records from a website takes only a few minutes of scraper setup.
Web Scraper utilizes a modular structure that is made of selectors, which instruct the scraper on how to traverse the target site and what data to extract. Thanks to this structure, data mining from modern and dynamic websites such as Amazon, Tripadvisor, eBay, as well as from lesser-known sites is effortless.
Once the data is scraped, download it as a CSV or XLSX file that can be further imported into Excel, Google Sheets, etc.
Web Scraper is a simple web scraping tool that allows you to use many advanced features to get the exact information you are looking for. It offers features like:
* Data scraping from multiple pages;
* Multiple data extraction types (text, images, URL’s, and more);
* Browsing scraped data;
* Exporting scraped data from a website to Excel;
It is dependent only on the web browser; therefore, no extra software needed for you to start scraping.
