How to Restrict a Macro from Running Automatically When Starting Microsoft Excel
Restricting a macro from running automatically when you start Microsoft Excel is pretty straightforward. You can manage this by adjusting your Excel settings or modifying the specific workbook that contains the macro. By following a few easy steps, you can prevent macros from starting up automatically, giving you greater control over your Excel environment.
How to Restrict a Macro from Running Automatically When Starting Microsoft Excel
In the following steps, we’ll go through the process of stopping macros from running every time you open Excel. This aims to improve your control over your files and enhance security.
Step 1: Open Excel in Safe Mode
Press and hold the Ctrl key while opening Excel.
Opening Excel in Safe Mode ensures that no macros or add-ins are loaded. You will see a prompt asking if you want to start Excel in Safe Mode. Click "Yes."
Step 2: Access the Developer Tab
Go to the "File" menu, then click "Options," and select "Customize Ribbon." Check the "Developer" option to add the Developer tab to your ribbon.
The Developer tab provides tools for managing macros and other advanced features. This step makes it easier to find and manage your macros directly.
Step 3: Open the Visual Basic for Applications (VBA) Editor
Click on the Developer tab and then click "Visual Basic."
The VBA Editor is where you can view and edit your macros. This is where you will modify the macro settings to stop them from running automatically.
Step 4: Locate the Workbook_Open Code
In the Project Explorer window, find the "ThisWorkbook" object under the VBAProject for your workbook. Double-click it to view the code.
The "ThisWorkbook" object contains events related to the workbook, including the Workbook_Open event, which runs macros when the workbook is opened.
Step 5: Disable or Modify the Workbook_Open Code
Find the Workbook_Open procedure and either comment out the code or modify it to include a conditional statement that prevents it from running automatically.
Commenting out the code means placing an apostrophe (‘) at the beginning of each line of code, effectively disabling it. Alternatively, you can add a condition to check if a specific requirement is met before running the macro.
After completing these steps, your macros won’t run automatically when you open Excel. This is particularly useful if you want to control when and how macros run, ensuring they only execute under specific circumstances.
