Google Docs uses Google Translate to help you translate entire documents into one of 64 languages.

Here's how to translate a document:

1. Go to the Tools menu, and select Translate document....
2. Type in the name of the new document, select the language into which you'd like to translate the document, and press OK.
3. A translated copy of your document will be created. You can access this copy in your Drive at drive.google.com.
