Can you 'drag and drop' text and drop formatting at once?
I don't know which application you are using but in Pages the simplest way is to use Paste And Match Style 

Under the Edit menu



option-shift-cmd-V


is the keyboard shortcut

So if you are pasting into a document that has no styles set it will be pasted in as the standard body



Different applications may or may not have the same functionality. I don't have MS Word on my machine so have no idea if this is the same for that application for example.
