Web Scraper插件简介

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.

Features
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);
* Scraping data from dynamic pages (JavaScript + AJAX, infinite scroll);
* 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.

How to begin scraping?
There are only a couple of steps you will need to learn in order to master web scraping:
1. Install the extension and open the Web Scraper tab in developer tools (which has to be placed at the bottom of the screen);
2. Create a new sitemap;
3. Add data extraction selectors to the sitemap;
4. Lastly, launch the scraper and export scraped data.
It’s as easy as that!

What can Web Scraper be used for?
* Lead generation – email, phone number, other contact detail related data mining from various websites;
* E-commerce – product data extraction, product price scraping, description, URL extraction, image retrieving, etc;
* Website content crawling – extract information from news portals, blogs, forums and so on;
* Retail monitoring – monitor product performance, competitor or supplier stock and pricing, etc;
* Brand monitoring – product review, social content crawling for sentiment analysis;
* Business intelligence – gather data for key business decisions, learn from your competitors;
* Big data extraction for machine learning, marketing, business strategy developments, researches;
* And much more.

mac chrome118 x86_64,"element scroll down " can not work

试用了一段时间,还是或多或少有些bug,官网论坛里也有很多人讨论issue问题,总结:简单少量爬取,确实是方便快捷的利器,大数据量或复杂逻辑爬取,还是用python吧。 定制数据采集,可V我:493882434

Tsai

深度采集還是不如迷你派來的采集正確。軟件後面新加的feature修修補補的不成樣子了。 不過畢竟是老牌

Allen

1.Data items should sorted by "web-scraper-order" field

张志

已经足够好用了:对我等非专业选手,使用也不是很难,网上教程挺多,例子也多,上手较为容易,结果比较满意,点赞!
