Whether a digital native or immigrant, you probably know the basic functions of Excel inside out. With Excel, it is easy to accomplish simple tasks like sorting, filtering and outlining data and making charts based on them. When the data are highly structured, we can even perform advanced data analysis using pivot and regression models in Excel. But the problem is, how can we extract scalable data and put them into Excel efficiently? This would be an extremely tedious task if done manually by repetitive typing, searching, copying, and pasting. So how can we achieve automated data extraction and scraping from websites to excel?
In this article, I will introduce several ways to save your time and energy to extract data from websites to excel through web scraping.

There are many ways to scrape data from websites using programming languages like PHP, Python, Perl, Ruby and etc. But here we'll just talk about how to scrape data from websites into excel for non-coders.
Getting web data using Excel Web Queries
Except for transforming data from a web page manually by copying and pasting, Excel Web Queries is used to quickly retrieve data from a standard web page into an Excel worksheet. It can automatically detect tables embedded in the web page's HTML. Excel Web queries can also be used in situations where a standard ODBC (Open Database Connectivity) connection gets hard to create or maintain. You can directly scrape a table from any website using Excel Web Queries.
The process boils down to several simple steps (Check out this article):

5. Select the appropriate one
6. Press the Import button.
Now you have the web data scraped into the Excel Worksheet - perfectly arranged in rows and columns as you like.
Getting web data using Excel VBA
Most of us would use formula's in Excel(e.g. =avg(...), =sum(...), =if(...), etc.) a lot, but less familiar with the built-in language - Visual Basic for Application a.k.a VBA. It’s commonly known as “Macros” and such Excel files are saved as a **.xlsm. Before using it, you need to first enable the Developer tab in the ribbon (right-click File -> Customize Ribbon -> check Developer tab). Then set up your layout. In this developer interface, you can write VBA code attached to various events.

Using Excel VBA is going to be a bit technical - this is not very friendly for non-programmers among us. VBA works by running macros, step-by-step procedures written in Excel Visual Basic. To scrape data from websites to Excel using VBA, we need to build or get some VBA script to send some requests to web pages and get returned data from these web pages. It’s common to use VBA with XMLHTTP and regular expressions to parse the web pages. For Windows, you can use VBA with WinHTTP or InternetExplorer to scrape data from websites to Excel.
With some patience and some practice, you would find it worthwhile to learn some Excel VBA code and some HTML knowledge to make your web scraping into Excel much easier and more efficient for automating the repetitive work. There’s a plentiful amount of material and forums for you to learn how to write VBA code.
