As an intelligent web scraper on both Windows and Mac OS, it automatically "guesses" the desired data fields for users, which saves a large amount of time and energy as you don't need to manually select the data. Octoparse is an easy-to-use web scraping tool developed to accommodate complicated web scraping for non-coders.
What are some of the most popular web scraping tools? There are so many more, literally countless reasons people may need data! I’m in the Machine learning/deep learning field and I need an abundance of raw data to train my bots.I’m a trader and I need UNLIMITED financial data to guide my next move in the market.I’m an eCommerce guy and I need to know how the price fluctuates for the products I’m selling.I’m a data analyst and there’s no way I can do my job without data.I’m a CEO and I need data on all business sectors to help me with my strategic decision-making process.
I’m a product guru, I need data for competitive analysis of the different products.I’m a marketing analyst and I need to collect data to support my marketing strategy.I’m a student and I need data to support my research/thesis writing.So what are some ways that data can be used to create values? I will go into great depth comparing the top five web scraping tools I’ve used before including how each of them is priced and what’s included in the various packages. There are many different web scraping tools available, some require more technical backgrounds and others are developed by non-coders. The process can be automated to the point where the data you need will get delivered to you on schedule in the format required.
One most recognized value of a web scraping tool is really to free one from unrealistically tedious copy and pasting work that could have taken forever to finish. In this case, Octoparse will extract some extra data you don't want to get.A web scraper can be easily understood as a tool that helps you quickly grab and turn any unstructured data you see on the web into structured formats, such as Excel, text or CVS. If you create two “Text list” loop to enter these two lists,Īnd Octoparse will execute an one-to-many match like this: We need to get the search results by entering A in text box one and 1 in text box two separately, or entering B and 2 separately, and etc. The second list for text box two is 1, 2, 3, 4. The first list for text box one is A, B, C, D. We have two lists for two separate text boxes on the search form. Let’s take the “Situation 2” for example. That is, Octoparse cannot deal with the “text list loop” when completing the search on a one-to-one basis. So I have two lists that need to "loop" in tandem with each other (List 1 > List 2).Ĭurrently it's hard for Octoparse to do this type of "in tandem" loop. When I enter "C" in box one, I need to enter "3" in box two to complete the search. When I enter "B" in box one, I need to enter "2" in box two to complete the search. That means for instance, when I enter "A" in box one, I need to enter "1" in box two to complete the search. The looping lists I have are each related. I have to conduct a search by entering TWO separate terms in TWO separate text boxes on the search form. (In other words, I'm not looping through Last Names for one company and then looping through the Last Names again for the next company and so on-instead-each combination of COMPANY NAME and LAST NAME make ONE RECORD that I need to search for each time). This loop needs to continue through an entire list of COMPANY NAMES that are directly related to LAST NAMES. Then the process needs to loop and search the combination of "Company B" with "Last Name B," then "Company C" with "Last Name C," etc., etc., etc. I need to search through a list of company names RELATED to the last name.įor example, I need to search for the combination of "Company A" with "Last Name A" at the same time. I have a list of company names and last names. Solutions are available for a related question here.
