Making web data extraction easy and accessible for everyone. Our goal is to make web data extraction as simple as possible. Configure scraper by simply pointing and clicking on elements. No coding required. Web Scraper can extract data from sites with multiple levels of navigation. It can navigate a website on all levels. Websites today are built on top of JavaScript frameworks that make user interface easier to use but are less accessible to scrapers. WebScraper.io allows you to build Site Maps from different types of selectors. This system makes it possible to tailor data extraction to different site structures. Build scrapers, scrape sites and export data in CSV format directly from your browser. Use Web Scraper Cloud to export data in CSV, XLSX and JSON formats, access it via API, webhooks or get it exported via Dropbox, Google Sheets or Amazon S3.
