Translate - Document task

The Translate - Document task lets you translate a single document file in real-time (synchronously) using Cloud Translation. You can directly translate formatted documents such as PDF and DOCX while preserving their original formatting and layout. For information about the supported file formats for document translation, see Supported file formats.

Cloud Translation is a Google Cloud service that allows you to translate text for more than 100 language pairs with the capability of auto language detection. For a list of all supported languages, see Supported languages.

Before you begin

Ensure that you perform the following tasks in your Google Cloud project before configuring the Translate - Document task:

  3. Select an existing integration or click Create integration to create a new one.

    If you are creating a new integration:

    1. Enter a name and description in the Create Integration pane.
    2. Select a region for the integration.
    3. Select a service account for the integration. You can change or update the service account details of an integration any time from the Integration summary pane in the integration toolbar.
    4. Click Create.

    This opens the integration in the integration editor.

  4. In the integration editor navigation bar, click Tasks to view the list of available tasks.
  5. Click and place the Translate - Document element in the integration editor.
  6. Click the Translate - Document element on the designer to view the Translate - Document task configuration pane.
  7. Go to Authentication, and select an existing authentication profile that you want to use.

    Optional. If you have not created an authentication profile prior to configuring the task, Click + New authentication profile and follow the steps as mentioned in Create a new authentication profile.

  8. Go to Task Input, and configure the displayed inputs fields using the following Task input parameters table.

    Changes to the inputs fields are saved automatically.
