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.

For more information about localizing the Looker user interface or number formatting, see the Localizing Looker documentation page.


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

Language Locale Code and Strings File Name
English en
German de_DE
Spanish es_ES
French fr_FR
Italian it_IT
Japanese ja_JP
Korean ko_KR

Brazilian Portuguese pt_BR
Portuguese pt_PT
Russian ru_RU
Swedish sv_SE
Turkish tr_TR
Simplified Chinese zh_CN
Traditional Chinese zh_TW
