🏆 Best Web Data Extractors for August 2021

You're looking for a data extraction software that will make your life easier? Web Data Extractor is the perfect solution. It's an easy-to-use and powerful data extraction software for web scraping, which allows you to quickly import, clean, explore and analyze data from the internet.

What is a web data extractor?

A web data extractor is a software utility that extracts all the information from any website as well as providing you access to information on who owns or hosts that website. They are not limited to extracting data from HTML pages but can also be used to extract text, video, sound, or images. 

Why do you need a web data extractor?

For many websites, a web data extractor is a prerequisite before being able to analyze the data for business insights. Web data extractors first get every piece of information they can about a page on the internet, such as the hostname, iframes, and anchor text links. They then gather all meta tags and extract any common web form elements with fields. Finally, they will export all of these items into an easy-to-read TSV file that can be imported into most spreadsheet programs.

Core features of the web data extractor

Point-and-Click Interface

Point-and-Click interface, or PC for short, is an intuitive interface for selecting and navigating interactive objects on a graphical user interface. Compared to command-line interfaces (CLI), it allows computers to be operated without memorizing tactics and strategies. Users of PCs might want more features but find the extra hassle of learning CLI worth it in the long run.


A website is a collection of publicly accessible, interlinked web pages that share a single domain name. Websites can be created and maintained by an individual, group, business, or organization to serve a variety of purposes. Together, all publicly accessible websites constitute the world wide web. Although it is sometimes called a web page, this definition is wrong since a website consists of several web pages. It is also known as a “web presence” or simply “site”.

Extract Multiple Pages

Any website that allows you to create a free trial account, extract data in bulk, and export without limits is great. It is possible to extract multiple pages, but it will depend on the website, and how many of their web pages have been scraped. There are other programs that can automate this process. You may need additional data scraping training for this one, or you might extend your current project scope too much, which could drive up costs.

Supports Dynamic Websites

Dynamic websites are designed with a database that continuously updates and displays new content. It is similar to a "normal" website, but what makes it dynamic is the fact that instead of just containing information laid out in HTML code on the page, it also contains some kind of script or looping process that pulls information from an external source and displays it when visitors come to the site.

Scheduled Extraction

A scheduled extraction in a data extractor is the automated process of extracting and storing data from an organization's various systems when those systems are offline. When extracting web data from the internet, the schedule is typically set at intervals of three to five days. This helps ensure one's inbox does not get backed up and also provides enough time for advertisers to adjust campaigns accordingly.

Types of web data extractors

Web Scraping 

Web scraping involves the process of extracting structured or unstructured data from a website with the help of a computer program. In other words, it's like there is a spider that crawls around on your website and picks up whatever they can with their little arms before taking them back to you. This form of web extraction is very efficient and will do well in situations where customers might want to pull only specific content.

Data Mining

Data mining means looking at large datasets for patterns and automatically drawing inferences about certain topics without having any prior information about those topics. It involves effective data collection and warehousing as well as computer processing. Businesses can learn more about their customers, develop more effective strategies related to various business functions, and leverage resources more optimally and insightfully.

Web Crawler

A web crawler is a web search engine bot that traverses the world wide web and grabs content from other sites while indexing them on behalf of its owner/operator. 

Full-text Data Extractor 

Full-text data extractor is the act of retrieving vast numbers (hundreds or even millions) of available text documents by employing a query technique called "partial string matching.

Frequently Asked Questions (FAQs)

No. You must specify the URL for any page before you extract it using a web data extractor. Since it does not capture all the information, some website owners may want to keep their site off-limits from the use by this application.

Yes. You can resume an interrupted session in a web data extractor. Use the 'File - Open' menu command to open the previously stopped session's log file.

Make sure the file exists on disk. The file must have a URL line-by-line, other format is not supported, WDE will accept only lines that start with HTTP:// text. Also, web data extractors will not accept URLs that point to image/binary files because those files will not have any text data to extract.

It seems you are using a high number of threads. Decrease the thread value to "5" in the "New Session - Other" tab. WDE can launch multiple threads simultaneously. But remember, too high a thread setting may be too much for your computer and/or internet connection to handle it and also puts an unfair load on the host server, which may slow the process down.

Few things may cause this: First, not all website owners put their email addresses on their website/contact page. Some websites use forms in their contact/support pages. Second, check the "Depth" setting. Depth tells WDE how many levels to dig down within the specified website.

Yes. Instructions on how to use web data extractor are on the web data extractor help page. You'll need a lat-long list of coordinates for each point you want to gather information about except for Facebook, which lists the location as a general region in their 'likes.'

Use the import query string to edit or create a new query. For specific searches, you can also specify a search engine and keywords in these fields. You may get many irrelevant results with general queries without specifying a particular term to search. You can also narrow your results by checking the "Specific Term" box.

A web data extractor will scrape your Facebook profile, check who has a non-private account visible to you (that hasn't already accepted your friend request), and display all their names in an orderly spreadsheet format. So, you can select which ones to unblock or delete.

Monitoring tools we use to monitor the database are primarily Nagios. We also make sure to pay close attention to spikes in load 50-90% higher than the average over a 10-minute interval, as this would indicate an issue with data extraction.

You can specify an overflow threshold in the config for your web data extractor. The process which extracts the data from the original URL and imports it into Neos exposes underscores. When you import into Neos, they are changed to spaces so that our assistant on top of SQL on top of MongoDB doesn't break INSERTs anymore.
