Google Translator is really good at what it does, i.e., translating text. You feed it with a string of text and instantly get the result in various other languages. It also supports translating entire web pages, but what if you have some MS Office documents to translate? Would you feed every single line of text one by one and get the output in your language of choice? Imagine the time it would consume, not to mention the inconvenience.
DocTranslator is a free, online service that allows you to translate Word, Excel and PowerPoint files, as well as plain text documents just by submitting the source file and getting the output result as a file itself. It uses Google Translate API, so the results remain as reliable as the ones with Translator itself.
The service supports over 50 languages, and does not impose any file size limits when submitting for translation. It is also a use as it is service, without any requirements for registration etc. Furthermore, the layout of your original document remains preserved, so there is no need for reformatting.
DocTranslator clams that all your data remains completely private and confidential, and nothing is stored by them.
