Web Scraper Features – Semalt Expert

Web scraper is a Chrome browser extension aimed to extract data from web pages. With this extension, you can create a sitemap or plan, that shows the most appropriate way to navigate a site and extract data from it.

Following your sitemap, Web Scraper will navigate the source site page after page and scrape the required content. Extracted data can be exported as CSV or other formats. Besides, this extension can be installed from Chrome Store without any problem.

Some of the features of Web Scraper are outlined right below

  • Ability to scrape multiple pages

The tool has the ability to extract data from several web pages simultaneously if it is stipulated in the sitemap. If you need to extract all images from a 100-paged website, it may be time-consuming for you to check each of the pages and get known which ones contain images and which ones do not. So, you can instruct the tool to check every page for images.

  • The tool stores data in CouchDB or browser's local storage
  • The tool stores sitemaps and extracted data either in the local storage of the browser or CouchDB
  • Can extract multiple data

Since the tool can work with multiple types of data, users can select multiple types of data for extraction on the same page. For instance, it can scrape both images and text from web pages at the same time.

  • Scrape data from dynamic pages

Web Scraper is so powerful that it can scrape data even from such dynamic pages as Ajax and JavaScript.

  • Ability to view extracted data

The tool allows users to view scraped data even before it is saved in the designated location

  • It exports extracted data as CSV

Web Scraper exports extracted data as CSV by default, but it can also export it in other formats.

  • Exports and imports sitemaps

You may need to use sitemaps multiple times so the tool can import and export sitemaps on request.

  • Depends on Chrome browser only

Unfortunately, this is rather a drawback that an advantage. It works exclusively with Chrome browser.
