Scrape webdata from Google Sheets, an alternative to IMPORTXML / IMPORTHTML

If you've ever tried to extract data from websites directly into your Google Sheets using the IMPORTXML (or IMPORTHTML) function, you know it can be a challenging task, especially if you're not well-versed in HTML or XPath queries. While IMPORTXML offers a way to scrape data, it comes with its own set of limitations and frustrations.

In this article, we'll explore the drawbacks of IMPORTXML and introduce you to a powerful alternative: IMPORTFROMWEB

Understanding IMPORTXML

Let's begin by understanding what IMPORTXML offers. This native function in Google Sheets allows users to import data from various structured data types such as XML, HTML, CSV/TSV, and RSS/Atom XML feeds. With just a URL and an XPath query, you can retrieve specific data from a webpage directly into your spreadsheet.

The function syntax is:

=IMPORTXML(url, xpath_query)        

Here's an example of how to use IMPORTXML to retrieve all links from Wikipedia’s Moon landing page:

=IMPORTXML("https://en.wikipedia.org/wiki/Moon_landing", "https://a/@href")        

However, the simplicity of the formula belies the complexity of finding the right parameters. To effectively use IMPORTXML, you often need to delve into the website's source code, locate the relevant HTML elements, and craft XPath queries. This process can be daunting, even for those with technical know-how.

Common Challenges with IMPORTXML

Although IMPORTXML can be effective, it has several limitations that may hinder its usability:

• Performance Issues: Using IMPORTXML multiple times in a sheet can slow down performance, causing the spreadsheet to become sluggish and unpredictable.
• Javascript-rendered websites are not supported: IMPORTXML cannot scrape data from websites rendered with JavaScript, which excludes many modern web pages.
• Technical Expertise Required: Understanding and writing XPath queries can be challenging for non-technical users.
• One URL, One XPath: Each IMPORTXML function can only handle one URL and one XPath query at a time, making it cumbersome for large-scale scraping.
