Disable Security Warnings 1. Disable Security Warnings Even after enabling macros, Excel may display a warning banner. To disable it, you need to combine enabling macros with using a trusted location. There is no option to completely remove the warnings without compromising security, but this method effectively bypasses them. 2. Automate Opening with Macros Enabled If you always use the same file, you can create a shortcut to it in your Windows Startup folder. This way, Excel will automatically open it with macros enabled, provided the file is in a trusted location. Place the shortcut in **C:\Users\[Username]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup**. 3. Verify and Test the Configuration Once all the settings are configured, close Excel and reopen your file. If everything is set up correctly, the macros should run automatically without warning. Test your line underlining macro to confirm that the automation is working as expected.
