There are many translators that translate English to the Spanish language and guarantee their accuracy. But none of the English-to-Spanish translations is 100% accurate. Many translation tools and software use mechanical translation, algorithms, and AI (Artificial Intelligence) which does not assure quality translation because the Spanish language is difficult and machines cannot know the expressions so they can be wrong sometimes. And if the translation service provider is using human translation where all the translation job is done by humans then there is a high degree of accuracy but it cannot be said 100% accurate because mistakes happen. Hence translating Spanish does not work 100% accurately, But it is true, Translator tools help you a lot and save time compared to having nothing.
