Admins can set the default locale and number format for a Looker instance on the Localization page in the General section of the Admin menu. Locales or number formats set at the user or user group levels will supersede a locale or number format set for the instance.


Certain Looker user interface text can be displayed in the following languages:

Language Locale Code and Strings Filename
English en
German de_DE
Spanish es_ES
French fr_FR
Italian it_IT
Japanese ja_JP
Korean ko_KR
Dutch nl_NL
Polish pl_PL
Brazilian Portuguese pt_BR
Portuguese pt_PT
Russian ru_RU
Swedish sv_SE
Turkish tr_TR
Simplified Chinese zh_CN
Traditional Chinese zh_TW

It is helpful if Looker developers who are localizing data models set the models’ default_locale parameters and the titles of their associated strings files equal to the default locale for the instance.

If no locale is set on this page, Looker defaults to en.
