Here’s how I converted one of my recent blog posts to a presentation.
1. Open document in Word for the web.
2. File > Export > Export to PowerPoint Presentation (Preview)
3. Choose a template and click Okay.
The feature uses #AI to suggest appropriate design themes. It currently supports only text content for transformation.
Other media content in my doc (e.g. images) needed to be manually added to the presentation. Nonetheless, a great headstart!
