Do you need a quick way to see which custom layouts are assigned to slides within your presentation?

You can do this manually by switching to the slide master view and then move your mouse over each layout to see which slides are assigned.

But there’s a quicker way!

Use a VBA macro.

The macro at the end of this post provides you with a way to quickly see all slide assignments in one simple window:

PowerPoint Slide Master Layouts Assignment

You can add it to your presentation by pressing Alt+F11 and inserting a new module into your VBA project before pasting the code (and the credit please)!

Then, once back in your presentation, simply press Alt+F8 and select the macro to run it.
