This is not a complete list but contains all the main formats you are likely to need for creating and sharing your documents. 

All the Export options are available from the Documents > Download menu.

The Import options are available from the Documents > Open menu if you have documents in the cloud. Or through the + Add insert menu if you are adding items to an open document. So that would be + Add > Image or + Add > File. 

Don't forget you can also drag and drop items from your file explorer too.
