The truth be told, there is nothing better than the good ol' Copy &
Paste method when it comes to transferring data. PowerPoint, however,
does allow you to transfer a whole Excel datasheet or a range of data
into a presentation.
Create a new chart slide or click on an existing one.
Double-click on the chart to open the datasheet.
Click the cell located in the upper-left corner.
Select Edit menu > Import File.
Find and double-click on the Excel file that you want to import data
On the Import Data Options dialog, choose a sheet or a range of datacells
