I want to share with you in this post some best free web scrapers for non-programmers who want to gain insight from large data-set online at low cost. I know that there are many many web scrapers that are available online but the freewares I would mention below is what I think the best for scraping web pages. These freewares are easy to use and help a lot for my web scraping tasks.

 

In this scraping process, I realized that it’s necessary to know about XPath expressions to better select the elements on the web pages, or at least to know how to copy the XPath of the elements by using browsers’ developer tools.

 

 

Web Scraping Plugins/Extension

 

  • Data Scraper(Chrome)

 

Data Scraper is very simple yet useful to scrape data from tables and lists of a single page into CSV or XLS files.

It’s free for most of its features and has paid subscription plans to suit your needs. No coding required. But you need to use Google Chrome browser for installing the plugin. I will show you how to use this simple web scraping tool.

 

1. Open this link and add the plugin to Chrome.

https://chrome.google.com/webstore/detail/data-scraper/nndknepjnldbdbepjfgmncbggmopgden/related?hl=en-US

After you successfully installed the extension, you can begin to scrape the data from the web page.

 

For instance, let's say we scrape the list of LinkedIn and retrieve some search results by searching for Marketing Associate jobs.

 

1) Right click on the URL and select "DataMiner - Get similar" from the context menu

 

2) The table will be automatically parsed.

3) You need to create a free Data Miner account to continue scraping the web page.

4) You can adjust the table/column selector with XPath.

5) Export your data to CSV file and open it in Excel or Google Sheets.
