Can we change the language of a woocommerce shop later when shop ready ?

You can change it later; translation only affects how admin/frontend strings get displayed.

Thank you, but do you mean that my admin will be displayed with the language selected ?

Yes

ok so its better that I change the language later as I am not able to read the final language that will be displayed ??

No way to show admin in English and website in another language ?

Possibly with code, but it’s not an option in WordPress.

Ok I will try to check more and post if I find information.
Thanks again for all.
