How Can I Scrape Data from JavaScript-Heavy Websites into Google Sheets?

Scraping data to Google Sheets from a website that uses JavaScript

The challenge:

Importing data from dynamic websites using Google Sheets built-in functions like IMPORTXML and IMPORTHTML fails because these functions rely on static content within the page.

Why it's not working:

The website you are trying to scrape uses JavaScript, which dynamically generates content on the page after it has loaded. This means that the data you want to import is not initially present in the source code, making it inaccessible to the functions.

Solutions:

There are several ways to overcome this limitation and scrape data from websites that use JavaScript:

• Developer tools: Use the developer tools in your browser to identify if the data is added dynamically. Disable JavaScript and reload the page to see if the data becomes visible. If it does, it may be possible to scrape it using Google Sheets functions.
• Inspecting the source code: Check the HTML/XML source code of the webpage for any embedded content, such as JavaScript objects or URLs that contain the data. You can then use IMPORTJSON, IMPORTDATA, or URL Fetch Service in Google Apps Script to retrieve and parse this data.
• Using specialized tools: Consider using dedicated web scraping tools or libraries that can handle dynamic content and bypass client-side restrictions.

Additional considerations:

• Use precautions to avoid violating the website's terms of service or robots.txt rules.
• Be aware of any rate limits or restrictions imposed by the website or API.
