Hi, 
 
I'm looking for recommendations on crating an agent that can translate multiple documents in bulk while keeping the original format, including Word, Pdf, Excel and PowerPoint. 
I have the same question (0)

    Hi @marc_sysco,
     
    Can you pleae tell the knowledge source? I mean, are your documents in local folders (onedrive) or in SharePoint library or what?

    Thank you @Haque
    All files are in a SharePoint library. And are usually Step by Step guides or training material.

    Hi @marc_sysco,
     
    I see two options for you:
    1. Use a Document Translation Service with Format Preservation: We can leverage Microsoft’s or third-party Document Translation APIs that explicitly support preserving layout and formatting during translation. For example, Microsoft Translator’s Document Translation API supports DOCX, PDF, PPTX, and XLSX formats and retains formatting and structure. Ref
    2. Batch Processing Support: Choose or build a solution that supports batch or bulk translation requests to handle multiple documents efficiently. This can be orchestrated via Power Automate or Azure Logic Apps.
     
     

    I am sure some clues I tried to give. If these clues help to resolve the issue brought you by here, please don't forget to check the box Does this answer your question? At the same time, I am pretty sure you have liked the response!

    If I compress everything:

    Best solution is:

    SharePoint → Queue → Azure Function → Azure Document Translation → SharePoint output

    NOT Power Automate-only.

    For bulk document translation while keeping the original format across Word, PDF, Excel and PowerPoint, the right tool is Azure AI Translator's Document Translation API, not a Copilot Studio agent doing the actual translation.
     
    Here is the recommended setup:
    Azure AI Translator (Document Translation) handles the heavy lifting. It translates Word, Excel, PowerPoint and PDF files while preserving layout and structure. It supports batch translation natively, so you can throw multiple files at it at once. It handles 130+ languages and the output file is the same format as the input.
     
    The architecture that works:
    1. Files land in a SharePoint library or Azure Blob Storage source container
    2. A Power Automate flow picks them up and pushes them to the Azure Translator batch job via the Translator v3 connector
    3. Translated files land in a target Blob container
    4. Flow copies them back to SharePoint or notifies users
    If you want a Copilot Studio agent on top of this, it acts as the interface to trigger the flow, let users pick source/target language, and report back status. The agent itself doesn't do the translation, it orchestrates the Power Automate flow that calls Azure Translator.
     
    What you need to set up:
    - Azure AI Translator resource
    - Azure Blob Storage account with source and target containers
    - Managed identity with RBAC roles on the storage account
    - Power Automate flow using the Microsoft Azure Translator v3 connector with the Start document translation action
     
    Microsoft has a documented tutorial for exactly this pattern with the Translator v3 connector in Power Automate. One thing to watch: if your Office documents contain images with embedded text, those images won't get translated. Only text content in the document body gets translated.
