Code Interpreter: Automate Excel Tasks

Microsoft expert guides using Code Interpreter in Copilot Studio to extract Excel invoice data and automate PO approvals

Key insights

  • Code Interpreter in Copilot Studio is a sandboxed Python runtime that lets AI agents read and manipulate Excel, CSV, and .xlsx files.
    It runs code safely to extract data, run calculations, build charts, and export results without manual scripting.
  • Excel processing tasks include reading sheets, computing sums and forecasts, applying conditional formats, and generating charts or new files.
    Outputs can be JSON, images, updated Excel or PDF files for reporting or downstream systems.
  • Automation and productivity gains come from converting manual Excel work into repeatable agent flows, saving time on cleaning, analysis, and bulk operations.
    The tool supports interactive visuals and bulk uploads for tasks like financial summaries or procurement lists.
  • No-code integration makes the feature usable for non-developers: enable Code Interpreter in a prompt, add a file input, and let the agent generate Python behind the scenes.
    It also connects to systems like Dataverse and SharePoint for bulk registrations or queries from stored files.
  • Sandboxed execution ensures security and controlled access to uploaded files while supporting large files and native previews for Excel, Word, and PDF outputs.
    Agents run only when the feature is enabled in prompt settings, limiting file visibility to the intended flow.
  • Getting started steps: create a Topic in Copilot Studio, add an AI Prompt that accepts a file upload, enable Code Interpreter, and test with a sample .xlsx (columns like Transaction ID, Vendor, Amount).
    Use clear instructions and placeholders so the agent maps columns to actions such as converting to JSON, creating charts, or triggering a PO creation workflow.
