There is no online translator which will give you a grammatically correct, a meaningful and a reliable translation for any language.
The main reason for this is that online translators cannot understand the subtleties of language and, in particular, are unable to distinguish between the various meanings of one word, for example “well” – is it a hole with water in, an adverb meaning that the performance of any activity is good, etc?
Unfortunately, there is no easy way around this. You will need a human translator to translate the text.
