Scraping a web page in VBA involves getting a reference to an HTML document and then processing its elements to extract the useful parts and write them to another location in a readable format. This video shows you how to do that using both Internet Explorer and basic XML HTTP requests. You'll learn a bit about the Document Object Model, as well as how to identify HTML elements by name and by tag type. You'll also see how to loop through various collections of HTML elements and their children using an example involving exchange rate tables.

What's better than scraping one web page? Scraping lots of them with the same procedure, of couse! This video explains how to loop over multiple pages using Microsoft's HTML and XML object libraries. You'll learn about HTML tags and classes, the Document Object Model and how to loop over elements on a page.

Excel VBA doesn't have a native method for downloading files from websites but you can declare an API function that will enable you to do this. This video takes you through the process of declaring the API function and using it in your code, along with a bunch of other useful techniques such as using folder pickers, creating folders with FileSystemObjects and opening a Windows Explorer window using the Shell function.
Thank you sir for your tutorials
please help me, i'm trying to run your example code, but it gives me error "access denied",
how can I solve this kind of error?
Hi, the most likely reason for the error is that the Wise Owl website has been updated to use https rather than http since the video was made. You should be able to replace any reference to "http" in the code to "https" to solve the problem.
I hope that helps!

Any plans to expand on XHR in Excel VBA, especially with session cookies?
There aren't, I'm afraid!
Thank you so much for the 3 videos about Web scraping. It did guide me a lot on how to identify HTML code. Your approach is great. I seem unable to find any routine of auto login (username, password) to web site via VBA code.
Hi, we don't have a video on how to do this but there are plenty of suggestions out there for ways to do this:
Of course the exact technique you'll use will depend on the page you're using to login but hopefully that's enough to point you in the right direction!
