How to Use VBA to Download Zip Files from URLs

Downloading zip files from the web can be useful for many purposes, such as saving data, updating software, or extracting information. However, doing this manually can be tedious and time-consuming. Fortunately, you can use Visual Basic for Applications (VBA) to automate this task and save yourself some hassle.

In this article, we will show you how to use VBA to download zip files from URLs, using the MSXML2.XMLHTTP object and the ADODB.Stream object. We will also show you how to handle errors and provide optional login and password parameters if required.

Step 1: Define the URL and the destination folder

The first step is to define the URL of the zip file that you want to download, and the destination folder where you want to save it. You can use variables or constants for this purpose. For example:

Const UrlFile As String = \"https://www.example.com/file.zip\" 'The URL of the zip file

Const Folder As String = \"C:\\Users\\username\\Downloads\\\" 'The destination folder

Step 2: Create an XMLHTTP object and send a GET request

The next step is to create an instance of the MSXML2.XMLHTTP object, which allows you to send HTTP requests and receive responses from web servers. You can use the CreateObject function for this purpose. Then, you need to use the Open method to specify the type of request (GET), the URL of the zip file, and optionally, the login and password if required. Finally, you need to use the Send method to send the request. For example:

Dim WinHttpReq As Object 'Declare a variable for the XMLHTTP object

Set WinHttpReq = CreateObject(\"MSXML2.XMLHTTP\") 'Create an instance of the XMLHTTP object

WinHttpReq.Open \"GET\", UrlFile, False, \"username\", \"password\" 'Open a GET request with optional login and password

WinHttpReq.Send 'Send the request

Step 3: Check the status of the response and save the file

The last step is to check the status of the response from the web server, and if it is successful (200), save the file to the destination folder. You can use the Status property of the XMLHTTP object for this purpose. To save the file, you need to create an instance of the ADODB.Stream object, which allows you to read and write binary data. You can use the CreateObject function for this purpose as well. Then, you need to use the Open method to open a stream, the Type property to set it to binary (1), and the Write method to write the response body of the XMLHTTP object to the stream. Finally, you need to use the SaveToFile method to save the stream as a zip file in the destination folder, specifying a mode of overwrite (2). For example:

If WinHttpReq.Status = 200 Then 'Check if the response is successful

Dim oStream As Object 'Declare a variable for the Stream object

Set oStream = CreateObject(\"ADODB.Stream\") 'Create an instance of the Stream object

oStream.Open 'Open a stream

oStream.Type = 1 'Set it to binary

oStream.Write WinHttpReq.ResponseBody 'Write the response body of the XMLHTTP object to the stream

oStream.SaveToFile Folder & \"file.zip\", 2 'Save the stream as a zip file in the destination folder with overwrite mode

oStream.Close 'Close the stream

End If

Error handling and final remarks

To handle any errors that may occur during this process, you can use an On Error GoTo statement at the beginning of your code, and a label at the end aa16f39245
