Google Translate already provided tools that let users translate snippets of text or entire web pages by entering a URL and choosing the source and output languages. Now you can also upload documents to translate.
Google quietly added the option sometime int he last few days. there’s not a ton of information about the new feature available, but it appears to handle TXT, HTML, XLS, DOC, and PDF files reasonably well. It choked on an OpenOffice Sheet ODS file I tried to upload.

The results are spit out in HTML format, so if you upload a spreadsheet you won’t get a translated, downloadable spreadsheet in return. Instead you’ll get an HTML table. But this isn’t a bad start. I wouldn’t be surprised if Google eventually adds the ability to open translated documents in Google Docs.
