The language the ThoughtSpot UI displays is based off of the locale in a user’s profile. The Preferred Locale preferences controls the language and data formats (date and number formats) by geographic locations. In addition to American English (en-US), ThoughtSpot supports:

Locale Language
da-DK Dansk
de-DE Deutsche
en-AU English (Australia)
en-CA English (Canada)
en-GB English (United Kingdom)
en-US English (United States)
es-US Español (latín)
es-ES Español (España)
fr-CA Français (Canada)
fr-FR Français (France)
it-IT Italiano
nl-NL Nederland (beta)
nb-NO Norsk
pt-BR Português (Brazil)
pt-PT Português (Portugal)
fi-FI Suomi
sv-SE Svenska
zh-CN 中文(简体)
ja-JP 日本語

Date and number formats change to reflect your locale. So, if you set Japanese as your default locale in your profile settings, then the interface will update to reflect that after you refresh your page.

Keywords, operators, and error messages are included in the translated material. (A keyword reference for all supported languages is included in this documentation under “Keywords in Other Languages”.)

Formulas, however, are not translated. Also, all metadata remains as user inputted.

For example, if you are using ThoughtSpot in the US, the number formatting should look like this: xxx,xxx.xx. And in Europe, it should look like this: xxx.xxx,xx.
