Web Scraper - Free Web Scraping 插件原文介绍

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.

Data extraction is run on your browser and doesn’t require anything to be installed on your computer. You don't need Python, PHP, or JavaScript coding experience to start scraping. Additionally, it is possible to completely automate data extraction in Web Scraper Cloud.

Once the data is scraped, download it as a CSV or XLSX file that can be further imported into Excel, Google Sheets, etc.
