Product guide
The Shortcut agent inside the workbook you already have open in Excel.
The Shortcut Excel add-in opens as a panel inside Microsoft Excel and works interactively on the workbook in front of you. It uses Microsoft’s official add-in interface, so Excel stays in control of the file at all times.
Add Shortcut from Microsoft AppSource or your organization’s admin deployment.
Local files and files opened from cloud storage both work.
Shortcut reads and edits the open workbook through Microsoft’s add-in interface.
Excel owns the file throughout, so save and share as usual.
Every Excel add-in, from any vendor, works through Microsoft's official add-in interface (Microsoft calls it Office.js). That interface gives an add-in structured access to the workbook the user has open, and deliberately nothing more: no general access to the computer, no ability to launch programs, and no direct control over every desktop Excel feature.
This is a security feature of Excel itself. It means Shortcut can safely work on your open workbook, whether it came from local storage, OneDrive, SharePoint, or another supported location, while Excel keeps ownership of the file. It also means that editing a workbook opened from cloud storage does not let the add-in browse the rest of that storage account.
Shortcut edits the workbook currently open in Excel, whether it came from local storage, OneDrive, SharePoint, or another supported location.
Attach supporting files so the agent can use them as context alongside the open workbook.
Use cloud sign-in, web research, and MCP connectors. Connectors can run on hosted servers or a network the add-in can reach, subject to browser access and organization policy.
Microsoft’s add-in API (often called Office.js) defines what any Excel add-in can do. Shortcut cannot freely run VBA or use every desktop Excel automation feature. For full desktop Excel automation, use the Shortcut CLI and desktop app on Windows.
An Excel add-in cannot browse your filesystem or launch processes. It can connect to an already-running MCP connector when browser access and organization policy allow it.
Editing a workbook opened from OneDrive or SharePoint does not let the add-in browse the rest of that storage account. Other files must be attached or retrieved through a supported integration.
Yes. It is a panel inside Excel and works directly on the open workbook.
Yes. It requires a supported version of Excel with Microsoft’s ExcelApi 1.17 feature set.
Not generally. It works with the open workbook and files you explicitly attach. It cannot browse your filesystem.
No. It is designed as an interactive Excel experience. For unattended runs, use the Platform API.
