Backend languages

You can change the backend language of Sitefinity CMS by installing one of the existing language packs or by exporting all labels and messages, translating them, and importing them back in Sitefinity.

On Sitefinity CMS Marketplace, you can freely download the following language packs:

  • Arabic
  • Chinese
  • Dutch
  • French
  • German
  • Italian
  • Japanese
  • Portuguese
  • Russian
  • Spanish

If you want to have Sitefinity CMS backend in another language, you must export, translate, and import all labels. To change the language of Sitefinity CMS backend, perform the following:

  1. Click Administration » Setting » Languages.
  2. Under Default language for the backend system, select the backend language in which you want to use as a source language for the translation.

    PREREQUISITE: Before you select a backend language, you must have added it. For more information, see Administration: Language settings » Adding backend languages.

  3. Click Save changes.
  4. Click Administration » Labels & Messages.
    The Labels & Messages page appears.
    • If the language you want to use as backend language is one of the languages available on Sitefinity CMS Marketplace, perform the following:
      1. Go to, find the add-on with the language you want to use. Click Learn more.
      2. Click Download button.

        The labels and messages are exported as a Microsoft Excel Worksheet (.xlsx file).
        The file opens, displaying all labels and messages ordered alphabetically.
      2. You translate the labels by entering their translation directly in the Excel file.

        IMPORTANT: You can only change columns Value and Description. Do not modify cells in columns ClassId and Key.

      3. Save the Excel file (a file with .xlsx extension).
  5. On Labels & Messages page, click Import language pack button.
  6. Select the language for which you want to import a translation of labels and messages.
