==================

Dear all,
I need to add French to my active survey (originally in German). However, after adding French to the survey languages, nothing happens when I run the quick translation. More specifically, the following sections simply remain blank (Survey title and description, Welcome and end text) or are still in German (Question groups, Questions, Subquestions, Answer options). Only the emails have been translated.

Is the quick translation tool only meant to make it easier for me to translate questions, or is there a way to actually translate them?

Thanks in advance!

Please refer to the manual. If using the Auto Translate feature, you may need a Google API key.

Yes, that's how "quick translate" works.
A mask, on the left the original language, on the right you enter the transaction.

To use Google translate you have to enter the "Google Translate API key"  into your "Global settings".
This feature is called "auto  translate".

Read the manual about these features.

The email template is not really translated. You get the default template that is stored in the survey settings.

And I find automatic translations (still) too dangerous for using in surveys, where small differences in translation can make huge differences, because respondents depend exactly on what is written, while with an interviewer they can still explain certain things. Believe me, I have learned this the hard way. Years ago the Italian intern considered a little word in a a question of a longitudinal survey "not necessary" and deleted it. Bam. 10 percentage points difference to other countries and previous years for Italy. Explain that to your 10+ clients from major brands.

What I want to say: Automatic translations are so good today, that they became really dangerous. Why? Because things look and sound good, but might actually not be.

I use Google Translate and other tools on a daily basis. But I would never trust it with translating something automatically without thorough human revision.

It is so dangerous because it often sounds perfectly fine. But I already caught Google translate to leave out a simple "not". Believe me, it makes a huge difference to have the "not" in the sentence or not.

Just wanting to highlight the dangers. Rest like Tpartner and Joffm.
