VBA Web Scraping to Excel: The Complete Step-by-Step Guide for Beginners

If you use Excel regularly, you‘ve probably thought about pulling data from websites directly into your spreadsheets. With web scraping, you can extract information from the web for analysis and reporting. But learning an advanced programming language like Python can be daunting for beginners.

Luckily, it‘s possible to scrape data using only Visual Basic for Applications (VBA) – no other tools required!

In this comprehensive 2500+ word guide, I‘ll teach you step-by-step how to set up web scraping entirely in Excel VBA. Whether you have basic coding skills or are just starting out, this tutorial will show you exactly how to scrape websites and import useful data into Excel.

By the end, you‘ll have the foundations to build scrapers tailored to your specific business needs. Let‘s get started!

Why Web Scraping? The Benefits of Extracting Data from Websites

First – why web scrape in the first place? What are the use cases and benefits of extracting data from online sources?

Web scraping allows you to gather and analyze large amounts of data from across the web. According to DataProt, over 80% of leading companies use web scraping to collect online data for market research, monitoring competitors, discovering trends, and more.

With web scraping, you can automate the process of pulling data from websites instead of manually copying and pasting. This makes it possible to extract thousands or even millions of data points that would be impossible by hand.

Here are some of the most common uses and benefits of web scraping:

Price monitoring – Track prices and price history for products across retailers. Useful for monitoring competitors.
Market research – Gather data on customer reviews, product information, trends etc. from multiple sources.
News monitoring – Scrape and collect articles or news mentions from news sites.
Email list building – Extract email addresses or contact info posted online.
Data mining – Discover patterns and insights in large datasets scraped from the web.
Real estate – Pull property listings from real estate sites to monitor for new options.
Social media monitoring – Scrape posts and data from social platforms like Twitter.

The applications are nearly endless. Any public data on the web can potentially be scraped for analysis.

Why Use Excel VBA for Web Scraping?

Excel is already a popular tool for data analysis. Wouldn‘t it be convenient to scrape data directly into spreadsheets?

VBA provides a way to perform web scraping using Excel alone – no need to install any other software or languages.

Here are some of the top advantages of using Excel VBA specifically for web scraping:

No additional tools required – VBA comes bundled with Excel, so there‘s no new environment to install.
Familiar interface – Excel users can scrape data into a comfortable spreadsheet interface they already understand.
Easy to learn – The VBA learning curve is more gradual compared to advanced languages like Python.
Lightweight scraping – Good option for scraping small amounts of data. Not as robust for large scale scraping.
Clear documentation – Microsoft provides solid documentation for Excel and VBA.
Easily automate – Web scrapers can be scheduled or triggered with buttons in Excel.

Of course, VBA does have some downsides. Performance starts to lag with complex scrapers. And it can be difficult to deploy VBA scrapers outside of Excel.

But for basic personal web scraping tasks, VBA provides a lightweight way to get started with minimal new setup.

Next let‘s look at how to prepare your Excel environment for web scraping with VBA.

Step 1 – Install Microsoft Office and Excel

Since we‘ll be web scraping directly in Excel, the first requirement is having access to Excel itself!

If you already have Microsoft Office – great, you can skip ahead.

If not, you can download a free trial of Microsoft 365 here. This will provide 1 month access to Excel on your Windows or Mac computer.

I recommend choosing the Home edition which will offer the core Excel desktop app. No need for anything more advanced.

The installer will walk you through setting up Excel on your system. Make sure to enable macros when prompted – we‘ll be using VBA macros to create the web scraper functionality.

Once installed, open Excel and you should see a blank spreadsheet.

Time to move on to the coding portion!

Step 2 – Open the VBA Editor in Excel

The VBA editor is where we‘ll actually write the code for our web scraping scripts. Luckily it‘s built right into Excel already.

Here‘s how to open it up:

Click on the Developer tab in the Excel ribbon at the top. If you don‘t see the Developer tab, go to File > Options > Customize Ribbon and check the box to enable it.
Once the Developer tab is visible, click the Visual Basic button to launch the VBA editor.

You should then see a blank window like this:

This is the behind-the-scenes look at the VBA code powering Excel. We‘ll write our scraper code here soon.

Fun fact: VBA stands for Visual Basic for Applications. It‘s a programming language created by Microsoft to allow automation and scripting across Office products.

Step 3 – Add VBA Reference to Microsoft HTML Object Library

Since we‘re scraping web pages, our code will need to work with HTML elements and DOM objects.

We can access the required HTML objects by adding a VBA reference to the Microsoft HTML Object Library:

In the VBA editor, click Tools > References.
Check the box next to Microsoft HTML Object Library.
Click OK to add the reference.

This library contains all the objects like HTMLDocument and IHTMLElement that we‘ll use later to parse HTML from websites.

Step 4 – Create a VBA Module for the Scraper Code

VBA code is organized into modules – which are basically containers for specific chunks of code.

It‘s good practice to keep the web scraper code separate in its own module.

Follow these steps to create a new VBA module:

In the VBA editor, go to Insert > Module to create a blank code module.
Rename the module something like WebScraper by double clicking the name in the left sidebar.

Now we have an empty module called WebScraper ready for our code.

Step 5 – Write the Initial Function and Define HTTP Request Object

Let‘s start laying out the structure:

Sub ScrapeWebsite()

End Sub

This defines a new subroutine called ScrapeWebsite which will contain the web scraper logic.

Next we need to create an MSXML2.XMLHTTP object to make HTTP requests:

Sub ScrapeWebsite()

  Dim http As New MSXML2.XMLHTTP

End Sub

The http object will allow us to GET web pages and receive the response.

Step 6 – Open and Send HTTP Request to Website URL

Now we can use the http object to send a GET request to the target webpage:

http.Open "GET", "https://example.com" 
http.send

This will retrieve the HTML content from example.com and store it in the response.

The full code:

Sub ScrapeWebsite()

  Dim http As New MSXML2.XMLHTTP

  http.Open "GET", "https://example.com"
  http.send 

End Sub

Make sure to replace example.com with the actual URL you want to scrape!

Step 7 – Parse the HTML Response

After sending the GET request, the website HTML will be contained in the http.responseText property.

Let‘s capture that in a variable:

Dim html As String
html = http.responseText

Now the html string contains the full raw HTML from the web page.

We can parse it using VBA string functions like Split() and InStr() to extract the data we need.

For example, to grab all links:

Dim links As Object
Set links = http.responseXML.getElementsByTagName("a") 

For Each link in links
  MsgBox link.getAttribute("href")
Next link

This loops through anchor tags and prints out the href attribute.

There are many ways to parse HTML elements in VBA – explore the HTMLDocument object model for more examples.

Step 8 – Write Scraped Data to Excel Cells

Once we‘ve extracted the data, let‘s output it to the Excel worksheet.

We can place values in cells using the Range object:

Range("A1").Value = scrapedData1 
Range("B1").Value = scrapedData2

This will populate cells A1 and B1 with the scraped info.

You can reference ranges by cell coordinates like above, or use named ranges.

Step 9 – Run the Scraper Macro

Now that everything is coded up, it‘s time to actually execute the web scraper!

There are a few ways to run the VBA macro:

From the Developer tab, click Macros and select the scraper subroutine
Set up a keyboard shortcut to run it like Ctrl+R
Assign the macro to a button for one-click scraping

Once triggered, the macro will scrape the target webpage, parse the HTML, extract data, and output it into the spreadsheet.

And that covers the entire process of building a basic web scraper in Excel VBA!

Example: Scraping Product Prices into Excel

To make things more concrete, let‘s walk through a real-world example.

Say we want to scrape prices for laptops from an electronics site and import them into Excel.

Here is how we might build the VBA scraper:

Send request – GET the laptop listings page HTML
Parse response – Extract all <div class="price"> elements on the page
Loop elements – For each price div, grab the inner text containing the price
Output to Excel – Populate cells A1, A2 etc. with the laptop prices
Refresh and expand – Run the macro on a schedule to update prices, scraping additional product pages

This gives you an idea of how a real scraper might work. The process of sending requests, parsing responses, and outputting data follows the same general template.

With a little trial and error, you can adapt these steps to build customized VBA scrapers for your specific needs.

Comparing VBA Web Scraping to Other Languages like Python

VBA definitely provides an easy starting point for beginners new to web scraping. But you may be wondering – how does it stack up against more robust languages like Python?

Python is more powerful than VBA for large scale web scraping tasks. With Python libraries like Beautiful Soup and Selenium, you can build scrapers that run faster and can handle complex sites.

Here are some of the key differences:

Scraping Capabilities – Python has more advanced functionality like interacting with JavaScript sites. VBA scraping capabilities are more limited.
Speed – Python scrapers generally perform better at scale when scraping large datasets. VBA is slower.
Cross-platform – Python runs on Windows, Mac, Linux. VBA only works on Windows.
Code execution – Python scripts run independently. VBA macros rely on Excel application.
Support and libraries – More scraping libraries and resources available for Python.

However, VBA is probably quicker to get up and running if you barely code. And of course it‘s built right into Excel already.

So while Python is better for heavy duty scraping, VBA is ideal for simple scraping tasks where convenience is key.

When to Use VBA Web Scraping

Now that you understand the basics of how web scraping in VBA works – when is it most useful?

Here are some of the top use cases where I recommend VBA web scraping:

Scraping small amounts of data (less than 1,000 rows)
Extracting web data to manually review or analyze in Excel
Basic scraping needs for non-coders comfortable with Excel
Cross-checking data from another larger scraper
Scraping internal sites within your network
Simple scraping automations for personal use

VBA excels at those light duty scraping tasks. Need to check a value on an intranet site? Scrape 20 product listings for sampling? VBA can handle jobs like that with minimal fuss.

For larger production web scrapers, I would steer towards Python. But don‘t underestimate the power of VBA for easy ad-hoc scraping!

Useful Tips for Scraping with Excel VBA

Here are some handy tips I‘ve picked up over the years for improving your VBA web scrapers:

Add delays – Use WScript.Sleep to add delays between requests to avoid overwhelming sites.
Error handling – Wrap code in On Error blocks to gracefully handle errors and timeouts.
Enable CORS – Use XMLHTTPRequestOption property to enable CORS for modern sites.
Clear memory – Set object variables back to Nothing to free up memory after parsing.
Reference workbooks – You can scrape data from one Excel workbook into another using references.
Refresh data – Use a loop or scheduling to refresh scraped values on a cadence.

Mastering little optimizations like that will make your VBA scrapers more robust.
