Introduction
Are you tired of manually downloading docx files from a website, only to find that the process is tedious and time-consuming? Look no further! In this article, we’ll show you how to use VBA Excel to download a docx file through a browser, even when cookies and varying download times are involved. By the end of this tutorial, you’ll be able to automate the download process with ease, saving you time and increasing your productivity.
Requirements
Before we dive into the tutorial, make sure you have the following requirements:
- Microsoft Excel with VBA enabled
- A website that requires cookies to download a docx file
- Internet Explorer (we’ll be using it as our browser)
Step 1: Create a New VBA Project
Open Microsoft Excel and press Alt + F11
to open the Visual Basic Editor. Create a new module by clicking Insert
> Module
and rename it to DownloadDocx
.
' DownloadDocx module
Step 2: Set Up the Browser Object
In the DownloadDocx
module, declare the following variables:
Dim ie As Object Dim url As String Dim userName As String Dim password As String
Set ie = CreateObject("InternetExplorer.Application") ie.Visible = True
Step 3: Navigate to the Website and Log In
Set the URL of the website that requires cookies to download the docx file:
url = "https://example.com/download/docx"
Navigate to the website using the ie.Navigate
method:
ie.Navigate url Do While ie.Busy Application.Wait Now + TimeValue("0:00:01") Loop
Enter your login credentials and click the login button using the ie.Document.querySelector
method:
userName = "your_username" password = "your_password" ie.Document.querySelector("[name='username']").Value = userName ie.Document.querySelector("[name='password']").Value = password ie.Document.querySelector("[type='submit']").Click
Step 4: Wait for the Download Link to Appear
After logging in, wait for the download link to appear using a loop:
Do While ie.Document.querySelector("[href*='docx']").Length = 0 Application.Wait Now + TimeValue("0:00:01") Loop
Step 5: Click the Download Link and Save the File
Click the download link using the ie.Document.querySelector
method:
ie.Document.querySelector("[href*='docx']").Click
Wait for the download to complete using the ie.ReadyState
property:
Do While ie.ReadyState <> 4 Application.Wait Now + TimeValue("0:00:01") Loop
Save the file to a specified location using the ie.ExecWB
method:
Dim filePath As String filePath = "C:\Downloads\example.docx" ie.ExecWB 16, 3, filePath, 0
Step 6: Clean Up
Close the Internet Explorer instance and set the objects to nothing:
ie.Quit Set ie = Nothing
Full Code
Here’s the full code for your reference:
Sub DownloadDocx() Dim ie As Object Dim url As String Dim userName As String Dim password As String Dim filePath As String Set ie = CreateObject("InternetExplorer.Application") ie.Visible = True url = "https://example.com/download/docx" userName = "your_username" password = "your_password" filePath = "C:\Downloads\example.docx" ie.Navigate url Do While ie.Busy Application.Wait Now + TimeValue("0:00:01") Loop ie.Document.querySelector("[name='username']").Value = userName ie.Document.querySelector("[name='password']").Value = password ie.Document.querySelector("[type='submit']").Click Do While ie.Document.querySelector("[href*='docx']").Length = 0 Application.Wait Now + TimeValue("0:00:01") Loop ie.Document.querySelector("[href*='docx']").Click Do While ie.ReadyState <> 4 Application.Wait Now + TimeValue("0:00:01") Loop ie.ExecWB 16, 3, filePath, 0 ie.Quit Set ie = Nothing End Sub
Conclusion
In this article, we’ve shown you how to use VBA Excel to download a docx file through a browser, even when cookies and varying download times are involved. By following these steps, you can automate the download process and save time. Remember to adjust the code to fit your specific needs and website requirements.
Troubleshooting Tips
Here are some troubleshooting tips to keep in mind:
- Make sure you have the correct website URL and login credentials.
- Check the website’s terms of service to ensure that automated downloads are allowed.
- If the download link doesn’t appear, try adjusting the waiting time or using a more specific selector.
- If the file doesn’t download correctly, try adjusting the file path or checking the file extension.
Best Practices
Here are some best practices to keep in mind when using VBA Excel to download files:
- Always use error handling to handle unexpected errors.
- Use descriptive variable names and comments to make your code easy to read.
- Test your code on a small scale before running it on a large dataset.
- Consider using alternative methods, such as APIs or web scraping, if possible.
By following these best practices and troubleshooting tips, you can ensure that your VBA Excel code runs smoothly and efficiently.

Frequently Asked Question
Get the scoop on how to use VBA Excel to download a docx file through a browser, dealing with cookies and varying download times!
How do I use VBA Excel to download a docx file through a browser?
You can use the `URLDownloadToFile` API function in VBA to download a docx file through a browser. However, this method has its limitations. A more robust approach is to use an HTTP request library like `MSXML2.XMLHTTP` or `WinHttp` to send a GET request to the URL and save the response as a file. You can also use a third-party library like `curl` or `Wget` to download the file.
How do I handle cookies when downloading a docx file through a browser using VBA?
To handle cookies, you can use the `WinHttp` library, which allows you to set and get cookies. You can also use the `MSXML2.XMLHTTP` library with the `setRequestHeader` method to set the `Cookie` header. Alternatively, you can use a third-party library like `curl` or `Wget` that supports cookies. Make sure to store and manage the cookies properly to avoid any issues with the download process.
How do I handle varying download times when downloading a docx file through a browser using VBA?
To handle varying download times, you can implement a timeout mechanism using the `Wait` function or a `Do While` loop to wait for the download to complete. You can also use the `ADODB.Stream` object to download the file in chunks, which allows you to monitor the download progress and adjust the timeout accordingly. Additionally, consider using a asynchronous download approach using `MSXML2.XMLHTTP` or `WinHttp` to download the file in the background.
Can I use VBA Excel to download a docx file from a website that requires authentication?
Yes, you can use VBA Excel to download a docx file from a website that requires authentication. You can use the `WinHttp` library to send a GET request with authentication credentials, such as username and password. Alternatively, you can use a library like `MSXML2.XMLHTTP` to send a GET request with authentication headers. Make sure to handle the authentication credentials securely and comply with the website’s terms of use.
Are there any limitations or considerations when using VBA Excel to download a docx file through a browser?
Yes, there are several limitations and considerations when using VBA Excel to download a docx file through a browser. For example, you need to ensure that the website allows programmatic downloads, and you comply with its terms of use. Additionally, you need to handle errors, exceptions, and timeouts properly. Furthermore, be aware of the file size and type limitations, as well as the potential for antivirus software to flag the download as malicious. Always test your code thoroughly and consider alternative approaches, such as using an API or a dedicated download tool.
