Web scraping allows you to retrieve any publicly available data from the web. But each web page has a unique layout and stores different data. So, programmatically extracting data from a web page involves custom logic.
As you can imagine, building such scripts costs you time and money. Fortunately, several scraping services have been recently developed, and they enable you to scrape the web without writing a single line of code. This also means that anyone can use them, even non-technical users!
Here, you will learn how to extract data from Amazon product data with Octoparse, a no-code, easy-to-use, fully-featured scraping service. Let's learn everything you need to know about Amazon product scraping!
What Data To Scrape From Amazon
An Amazon product consists of several pieces of data, but the most important ones are:
Product name
Price
Discount (if present)
Product description
List of features associated with the product (if present)
Rating
Product images
All this info is what you should focus on while scraping an Amazon product. On the other hand, you may want to retrieve different data based on your goals.
Now, let's understand why you need an advanced tool to scrape data from Amazon.
Why You Need an Advanced Tool to Scrape Amazon
Amazon has implemented several ways to avoid web scraping. The most relevant challenges associated with scraping Amazon are:
Your IP could and probably will be banned
Each Amazon product page can have a custom layout
Each product can have different data
The Amazon product page changes quickly
So, writing a scraping script to allow all these challenges will cost you a lot of time, money, and effort. This is why you should consider adopting an advanced scraping tool that can deal with all these issues natively.
Now, let's delve into Octoparse, the tool chosen to scrape Amazon product data.
What Is Octoparse?

Octoparse is an advanced website crawler that empowers you to extract any kind of data you need from the web. It comes with several features, including auto-detection, task templates, advanced modes, pagination and infinite scrolling handling, data format changer, and more.
Keep in mind that Octoparse is based on an easy-to-use, intuitive, point-and-click interface designed to guide you throughout the data extraction process. So, no code is involved. But you can also use the Octoparse API program to run scraping tasks programmatically.
Octoparse also provides you with a scheduled cloud extraction feature to extract dynamic data in real-time via the cloud. Then, it comes with an API program, which I will show you how to use shortly. Furthermore, the tool reproduces human activity when exploring web pages to avoid being detected while scraping. But if this happened, it offers IP proxy servers and user agent string rotation.
So, it gives everything you need to avoid Amazon's anti-scraping policies!

This is what the Amazon product link looks like:
https://www.amazon.com/Apple-MacBook-13-inch-256GB-Storage/dp/B08N5KWB9H/ref=sr_1_3?keywords=macbook%2Bair&qid=1652428198&sr=8-3&th=1
Keep it at hand because you will need it in the next step.
3. Scraping Amazon product data with Octoparse in just a few clicks
Launch Octoparse, past the Amazon product link retrieved before in the URL bar, and press "Start".
This is what you should be seeing now:
Now, click on the page elements you want to retrieve and then select the "Extract the text of the element" option from the Tips panel. This way, you can start collecting data from the Amazon product page.
If you want to retrieve also the product images, click on the page element containing the image, click on ">" in the Tips panel, and select "IMG".
This way, you just told Octopare to consider the img HTML element. Now, click "Extract the URL of the selected image" to retrieve the image URL.
You can follow this approach to retrieve each product image.
Keep selecting the elements you want to scrape and retrieve all the Amazon product data you need. Also, remember to rename the data fields to make them easier to understand, as shown below:
Now, keep in mind that scraped data could contain unwanted characters or might not be in the desired format. Luckily, Octoparse allows you to clean the data and transform it into the format you want. Let's see how.
Consider the price data. This is what it originally looks like:
$949
.
99
The two newlines between the "." character should be removed. To achieve this, click the Price data field, then "…", and select "Clean data".
Now, click on "+ Add Step", and select the "Replace with Regular Expression" option.
Define a regular expression as follows:
Click on "Confirm," then on "Apply", and your "Price" data should now look like this:
$949.99
Clean all your data, and when you are ready, save your Octoparse task. Then, click on the "Run" in the upper right corner. Octoparse will ask you if you want to run the task locally or in the cloud.
In this case, a local run would be enough.
Wait for the task execution to finish:
Then, click on "Export Data" and select the data export format in the popup below:
This is an example of an output JSON you can get from Octoparse:
