How to convert Illustrator Text in AE layer text ?

Hello

I woud like to import Illustrator files with a lot editable words in After Effect. I want to animate letters with the tools of text layer.

Is it possible ? There is nothing in help.

The only solution proposed is to import a photoshop file with the text layers and to convert the photoshop layer : Layer> Convert to editable text. But i can't find this function in the layer menu when i select the photoshop layer in my timeline.

Thanks in advance for your help !
