VBA Excel to Download a Docx File Through Browser: A Step-by-Step Guide

Posted on

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

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

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

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.
