Mastering Excel VBA: Protect, Save and Close Multiple Files in a Folder

Managing multiple Excel files can often feel overwhelming, especially when you need to apply similar changes across many documents. Whether you are performing data analysis or preparing reports, having to repetitively open, modify, and save numerous files can be tedious. In this article, we will explore how to automate this process using Excel VBA to open, protect, save, and close multiple .xlsx files in a designated folder in an efficient manner. Let’s dive in!

The Problem

Suppose you have a directory filled with around 50 .xlsx files that you need to protect. Each sheet within those files requires the same protection settings, and you want to ensure that after modifying them, they are saved and closed automatically. Additionally, it's crucial to know how many files are located in the folder to confirm everything is working correctly.

Here's what you need in your solution:

Open multiple Excel files in a specified folder.

Apply protection settings to each sheet of those files.

Save and close each file after modification.

Display a dialog box to show the number of files found.

The Solution

We will write a VBA macro that fulfills all these needs. Below is the breakdown of our approach.

Step 1: Set Up the Environment

Before we start coding, open Excel and press ALT + F11 to access the Visual Basic for Applications (VBA) editor.

Step 2: Write the VBA Code

Copy the following code into a new module:

Step 3: Run the Macro

Once you’ve entered the code:

Press F5 or click on the Run button to execute the macro.

A dialog will appear asking you to select the folder containing your files.

Once you select the folder, the macro will run and apply the defined protection settings to the sheets of all .xlsx files in that folder.

Explanation of the Code

File Dialog: The code uses a file dialog box to allow you to select a folder.

Loop Through Files: The Dir function retrieves file names matching your criteria. It loops through each file until all have been processed.

Protect Sheets: Within each workbook, all sheets are protected using pre-defined settings.

Display Message: After processing, a message box shows how many files were processed for confirmation.

Conclusion

Automation using Excel VBA not only saves time but also reduces the potential for human error in repetitive tasks. By implementing this simple macro, you can efficiently handle numerous Excel files, ensuring they’re all uniformly protected and saved.

Now, it’s time to take control of your Excel workflows and maximize efficiency with VBA scripting! Happy coding!
