If you need to translate texts while being in Google Calc there is a super easy way to do it.

Google included GOOGLETRANSLATE formula.

Here an example translating a text:

=GOOGLETRANSLATE("Hello","en","es")

If you want to autodetect the source language do that:

=GOOGLETRANSLATE("Hello","auto","es")

And to load the content directly from a field:

=GOOGLETRANSLATE(F12,"auto","es")
