Are you looking for a YouTube comment scraper for sentiment analysis? If yes, then you have come to the right place. This article helps you to scrape YouTube comments using the two easiest methods.

Currently, YouTube has over 2+ billion active users per month. The videos on YouTube are full of thousands of users’ comments. Scraping these YouTube comments can help you do many cool and exciting things. The information mined from YouTube comments can help you build machine learning models, perform user sentiment analysis, create large datasets, and perform data analysis.

So, whether you are a researcher, a student, or a data engineer, the following content can help you get YouTube comments for further analysis. Let’s see different methods to extract YouTube comments data with and without coding.

If you are wondering whether YouTube comment scraping is legal or not, the short answer is YES, it is legal.

YouTube contains thousands of data valid for research, marketing, and ads. Most of the public comments on a YouTube video give a good insight into what users think about the posted video.

Since the YouTube comments data is publicly available, you can easily copy-paste it into a spreadsheet or excel and create a dataset. Using that dataset, you can perform sentiment analysis or apply your AI algorithms to it.

But, manually copying data to an Excel sheet is time-consuming and not an appropriate solution if a video has thousands of comments. That is why you need web scraping tool.

Web scraping is a way to read data of a website using an automated tool or programming script. Once the data is read, the tool helps you save and store the publicly available big data in an organized format that you can use for research, i.e., sentiment analysis.

Therefore, it is legal to scrape YouTube comments because they are meant for the public. Not only YouTube comments, but you can scrape any publicly available data on the internet, and it is legal to do so.

Scrape YouTube Comments with Python

Python scripts provide another powerful way to scrape YouTube comments. But, this method is complex if you do not have computer programming experience.

Note: Make sure you have a Python environment setup on your computer before proceeding with this method.

How to scrape YouTube comments using Python programming language

Step 1: Install Google Chrome on your computer.

Step 2: Once done, install the ChromeDriver by clicking here.

Step 3: In your Python code, import the following libraries needed to perform YouTube comments data scraping.

import time
from selenium.webdriver import Chrome
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

These libraries are needed to crawl through YouTube comments that are dynamically loaded. Don’t worry if you don’t know precisely the purpose of every library used in the process.

Step 4: Add the below code to scrape YouTube video comments.

data= []
youtube_video_url= "https://www.youtube.com/watch?v=kuhhT_cBtFU&t=2s"

with Chrome(executable_path=r'C:\Program Files\chromedriver.exe') as driver:
    wait = WebDriverWait(driver,15)
   for item in range(200):
        wait.until(EC.visibility_of_element_located((By.TAG_NAME, "body"))).send_keys(Keys.END)

    for comment in wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, "#content"))):

Here, you have created a Python loop that will loop through the comments of your YouTube video and, during each iteration, append the scraped comments in the data field. Also, change the YouTube video link to your desired video from the youtube_video_url variable.

Step 5: Visualize the scraped YouTube comments using Python’s Pandas library. You need to add the following lines of code at the end of your python file.

import pandas as pd
df = pd.DataFrame(data, columns=['comment']
