Friday, March 02, 2018

Data scraping, sometimes called web scraping, data extraction, or web harvesting, is simply the process of collecting data from websites and storing it on your local database or spreadsheets. For the uninitiated, data scraping may sound one of those scary tech buzzwords. But it’s more conceivable than you think. Data scraping tools come in handy not only for recruitment purposes, but also in marketing, finance, e-commerce and many other industries.

As there are different web scrapers, a problem appeared: which one is the best custom scraper focused on our specific needs and scrape everything? Most off-the-shelf web scrapers are often quite generic and mostly designed to perform common and simple task. That’s to say, they may not appear to be as flexible and universal as you’d expect. To this end, I would discuss the pros and cons of 10 best popular data scraping tools for your reference. You may find the most suited data scraping tool that’s tailored to your needs.

 

 1. Octoparse

License: Free

Website: https://www.octoparse.com/ 

Octoparse is a free and powerful web scraper with comprehensive features used for extracting almost all kinds of data you need from the website. You can use Octoparse to rip a website with its extensive functionality and capabilities. With its point-and-click UI, Octoparse allows you to grab all the text from the website and thus you can download almost all the website content and save it as a structured format like Excel, HTML, CSV, or your databases without coding. And you could extract many tough websites with difficult data block layout using its built-in Regex tool, and locate web elements precisely using the XPath configuration tool. You will not be bothered by IP blocking any more, since Octoparse offers IP Proxy Servers that will automates IP’s leaving without being detected by aggressive websites.

Pros: Octoparse is the best free data scraping tool I’ve met. The free version provides the most powerful functionality with unlimited pages for crawling compared to other data scraping tools I list below. The premium versions are also competitive. More advanced, with customized settings you could scrape almost every tough websites.

Cons: Unfortunately, Octoparse couldn’t scrape data from PDFs. Nor could it download the images directly though it allows you to extract the URLs of the images.

 

2. Parsehub

Like Octoparse, ParseHub is a visual data extraction tool that can handle interactive maps, calendars, search, forums, nested comments, infinite scrolling, authentication, dropdowns, forms, Javascript, Ajax and much more with ease. The desktop application of Parsehub supports systems such as windows, Mac OS X and Linux, or you can use the web app that is built within the browser. ParseHub offer both a free plan for everyone and custom enterprise plans for massive data extraction. 

Pros: Parsehub supports more systems compared to Octoparse. And it is also very flexible to scrape data online with different needs.

Cons: Parsehub is more user-friendly for programmers with API access. The free version is quite limited with only 5 projects and 200 pages per run. Like Octoparse, it didn’t support documentation extraction. And some of the more advanced functions are tricky sometimes.

 

3. Content Grabber

Content Grabber is a powerful multi-featured visual web scraping tool used for content extraction from the web. It can automatically collect complete content structures such as product catalogs or search results.

Pros: Content Grabber provides more options for users with many third-party tools. Users are allowed to debug the script that isn’t supported by Octoparse or Parsehub.

Cons: Content Grabber doesn’t provide free version and its pricing starts from $149/month, which is quite expensive especially considering that the functionality of the lower version are available to Octoparse free version.
