How to Enable macros for individual workbooks?

Macros can be enabled for a specific file in two ways: directly from the workbook and via the Backstage view.

 Enable macros directly via security notice:

When you first open a workbook containing macros with the default macro settings, the yellow security warning bar appears at the top of the sheet, right under the ribbon:

The Microsoft Excel Security Notice will be displayed if the Visual Basic Editor is open at the time you open the file with macros:

If you are confident in the file’s origin and that all macros are safe, click the Enable Content or Enable Macros button. This activates the macros and marks the file as a trusted document.

Turn on macros in Backstage view:

The Office Backstage view is another way to enable macros for a specific workbook. Here’s how to do it:

• Click the File tab, then Info from the left menu.
• Click Enable Content > Enable All Content, in the Security Warning area.

Your workbook, like the previous method, will become a trusted document.

How to Enable macros for one session?

In some cases, enabling macros for a single instance makes sense. For example, suppose you received an Excel file containing VBA code that you want to investigate but do not want to make it a trusted document.

The steps below will walk you through the process of enabling macros for the duration of the file’s open state:

1. Navigate to the File tab > Info.
2. Click Enable Content > Advanced Options in the Security Warning area.
3. Select Enable content for this session in the Microsoft Office Security Options dialogue box, then click OK.

This enables macros for a single-use. The warning will reappear if you close and then reopen the workbook.
