Using Visual Basic for Applications you can insert Excel charts into a new PowerPoint presentation programmatically rather than using the cumbersome copy-and-paste method.

Both the Excel sheets and PowerPoint slides are used side by side and, we often copy the tables and charts from Excel, and paste them into PowerPoint slides to make a slideshow presentation.

You can also use PowerPoint's "Duplicate" function, which will create a copy of a slide automatically, without having to paste anything.
