Agent Mode continuously loading
Hi all, I installed Excel Labs today and have tried to use https://www.microsoft.com/en-us/microsoft-365/blog/2025/09/29/vibe-working-introducing-agent-mode-and-office-agent-in-microsoft-365-copilot/ for Excel in the web. However, no matter which prompt I use, it just loads continuously, even when left for hours. Has anyone got this working? Or know how to resolve this? I appreciate it's a Preview feature, so happy to wait if it's a temporary glitch, but thought it'd be worth checking.
Data Reconciliation Assistance Needed – Time Range & Sum Matching
I have two sets of data that need to be reconciled. Specifically, I’m trying to identify which combinations of numbers from these datasets can sum up to a specific target value. Additionally, the reconciliation should only consider entries that fall within a defined time range—from approximately 8:00 AM on one day to 10:00 PM the following day. I’ve tried using Solver and Goal Seek, but the results don’t seem accurate. I also attempted using Microsoft Copilot, but the outcome still appears incorrect. Could you assist with identifying or generating the correct combinations based on the criteria above?
Explain Formulas with Copilot—Now on the Grid
Understanding complex formulas in Excel just got a lot easier. The new Explain Formula feature turns Copilot into your inline assistant, delivering clear, step-by-step breakdowns directly on the grid, right next to your data, no need to switch context or open the chat pane. What makes this especially powerful is that the explanations are contextual, grounded in your actual data and workbook, not generic descriptions. By bringing the explanation to where you’re working, Copilot helps you stay in flow. It’s a seamless, in-the-moment experience that makes it easy to scan, understand, and act on formulas right where you need it most. How It Works Here’s how to get an explanation in just a few clicks: Select a cell with a valid formula A Copilot icon appears next to the cell Click “Explain this formula” from the dropdown Copilot shows a step-by-step explanation directly on the grid Need to dive deeper? Click “Chat with Copilot” to continue the conversation in the side pane Note: If the Copilot chat pane is already open, the explanation will be displayed there instead of on the grid. What It Does: Contextual Formula Explanations When you select a formula cell, Copilot can now explain what that formula does using a dedicated card shown in the grid. Helping you quickly understand what the formula does based on your actual data and context, not just a generic description. This makes it easy to: ✅ Understand the formula’s goal in your workbook ✅ Learn how it works, function by function ✅ Build confidence without ever leaving your sheet For example, given this formula: =I4 * XLOOKUP(H4, $L$4:$L$7, $M$4:$M$7) With just a click, Copilot will explain that: Because the explanation is tailored to your actual data and scenario, it’s faster to grasp, easier to verify, and more relevant to your work. Copilot provides the clarity you need right where you need it. Copilot Can Explain Any Excel formula No matter how simple or complex, Copilot can explain any Excel formula. Whether you're working with math, logic, references, arrays, or text manipulation, Copilot helps you understand what’s going on and why. Availability This feature is gradually rolling out to Excel for Windows and Excel for the web. Feedback We’d love to hear how this new experience is working for you. Let us know: ✔️ Was the explanation clear and easy to understand? ✔️ Was it easy to access the explanation when you needed it? ✔️ Did the overall experience feel intuitive and helpful? Just click the 👍 or 👎 at the bottom of the Copilot response to share your thoughts. Your feedback helps us refine the experience and prioritize what’s next.
