I have completed my form in English (default language). I added Arabic as a second language in the panel. But in Preview, there is no text. Is it possible for forms to be auto translated from English to Arabic and vice versa? Or do we have to do it manually in XLS? How do you do it in XLS?
Welcome to the community @devan! You will have to do them manually as outlined in our support article Adding Another Language in the Project Dashboard or Adding Another Language to your XLSForm whichever you feel comfortable with.
Welcome in the community.
You may find additional hints here
Use primary language when translation isn't available.
And esp. for Arabic here
Multi-language (AR/EN) survey.
