I keep getting this from Copilot when I ask for help with an excel file that is located on my desktop and has the .xlsx format: " but the workbook-processing tools are temporarily returning an error before I can modify the file."

    That error can occur because the workbook is stored in a local path. For Microsoft Copilot file access, local paths are not supported for uploaded or cloud-hosted file workflows, and moving the file to OneDrive or SharePoint is a supported troubleshooting step.

    Try this:

    1. Open the workbook in Excel.
    2. Select File > Save As.
    3. Save the file to OneDrive or SharePoint instead of the Desktop.
    4. Reopen the cloud-saved copy.
    5. Try Copilot again.

    Also check these file conditions:

    • Make sure the workbook is a modern Excel format such as .xlsx.
    • If the file came from an older or different format, save it again as Excel Workbook (.xlsx).
    • If the file is checked out in SharePoint, check it back in, then close and reopen it.
    • If a SharePoint site requires check-out for editing, use Excel for the web for those files.

    If the file is in a third-party storage location, move or copy it to OneDrive or SharePoint before using Copilot with that file.
