I just purchased Don't Starve and have been playing it on my Chrome browser. I've already unlocked several researches and a new character. Is there any way to transfer this data to the Steam version?
You should be able to follow these directions to import your save file:
Copy this URL and put it into chrome(Without quotes):
Right click on each file and save them into a folder somewhere (And remember where it is)
Open Don't Starve and choose import, Select that folder and import your save!
