How to Enable Macros in Excel
Excel macros can save time by automating repetitive tasks, but for security reasons, they’re often disabled by default. If you’ve ever opened a workbook and seen a warning about macros, Excel is protecting you from potentially unsafe code.
This guide explains how to enable macros in Excel safely and when you should — and shouldn’t — allow them.
Why Excel Disables Macros by Default
Macros can contain VBA code that runs automatically. While macros are powerful, they can also be misused if they come from untrusted sources.
Excel disables macros to:
- Protect against malicious code
- Prevent unauthorized automation
- Reduce accidental changes to data
Understanding when macros are safe is just as important as knowing how to enable them.
How to Enable Macros in Excel (Temporarily)
When you open a macro-enabled workbook (.xlsm), Excel may display a security warning.
To enable macros temporarily:
- Open the workbook
- Click Enable Content in the security warning bar
This enables macros only for the current session.
How to Enable Macros Using Trust Center Settings
To change macro settings permanently:
- Go to File → Options
- Select Trust Center
- Click Trust Center Settings
- Choose Macro Settings
Common options include:
- Disable all macros with notification (recommended)
- Disable all macros except digitally signed macros
- Enable all macros (not recommended)
For most users, enabling macros with notification provides the best balance of security and flexibility.
How to Enable Macros for Trusted Locations
If you frequently use macro-enabled files from a known source, you can add a trusted location.
Steps:
- Open Trust Center Settings
- Click Trusted Locations
- Add the folder where your macro files are stored
Files in trusted locations open with macros enabled automatically.
Macros on Windows vs Mac
Macro settings differ slightly depending on your system:
- Windows offers more granular macro controls
- Mac supports macros but with fewer customization options
The general safety principles remain the same on both platforms.
When You Should NOT Enable Macros
Avoid enabling macros when:
- The file comes from an unknown source
- You don’t understand what the macro does
- The workbook was downloaded unexpectedly
When in doubt, don’t enable macros.
Macros and Automation Workflow
Macros are most useful when combined with other Excel features.
For example:
- Use macros to format reports
- Use formulas for calculations
- Use PivotTables for summaries

Using Macros in Dashboards and Reports
Macros are often used to:
- Refresh data connections
- Update dashboard layouts
- Export reports automatically

Final Thoughts
Enabling macros unlocks powerful automation in Excel, but security should always come first. Only enable macros when you trust the source and understand their purpose.
Used responsibly, macros can save hours of repetitive work and improve consistency across reports.
