This task is one section of Odoo administration: seven setup tasks for admins, with 6 related tasks on one page.
1. Add the language
Open Settings and click Add Languages in the Languages section. Select one language and click Add. You can also open your profile and use the globe beside Language.
2. Switch one user
On your own profile, choose Language. For someone else, open Settings → Manage Users, select that user, and set Language on the Preferences tab. Reload. Menus for that user should change. Other users stay as they were.
3. Set the website separately
Go to Website → Configuration → Settings. Install the language if it is not listed, select it under Languages, and save. A user’s backend language does not add that language to the public site.
4. Expect gaps
Some of your own field labels and product names stay in the language you typed. Translate those records. Do not assume every string is covered.
5. Frequently asked questions
Does this translate my product names?
No. You entered those. Translate the product if the shop needs it.
Can each user have a language?
Yes. The preference is per user.
What if the language is missing from the list?
Add it from Settings first. A user can only choose a language that has already been added.
6. Related articles and next steps
Odoo documents adding a language in the Odoo 19 languages page, and adding it to a website in the website translations page.
