If you scroll through long Excel worksheets and lose track of your headers, freezing the top two rows is one of the quickest productivity wins you can apply — it keeps labels visible, reduces input errors, and makes navigation instantaneous even in very large sheets. This guide shows the...

Microsoft has quietly folded generative AI into Excel’s calculation engine with a native worksheet function — =COPILOT(... — that accepts plain‑language prompts, reads cell ranges as context, and returns live, spillable outputs directly into the spreadsheet grid. Early previews show it can...

Microsoft has embedded a new AI formula, =COPILOT, directly into Excel’s grid, promising natural‑language automation for summarizing text, classifying feedback, and generating content—while simultaneously cautioning users not to rely on it for “any task requiring accuracy or reproducibility.” In...

I had been ignoring Power Query for years, treating Excel like a calculator with a few handy formulas—until a messy, cross‑vendor CSV pile forced me to learn the tool everyone always brags about. What started as a tedious weekend of copy‑pasting and find‑and‑replace turned into a few well‑chosen...

Microsoft has quietly changed one of Excel’s oldest conventions: now you can call an AI assistant from inside a worksheet cell the same way you call SUM or VLOOKUP — with a new COPILOT function that accepts plain‑language prompts, references ranges and tables, and returns dynamic, spillable...

Microsoft's latest change to the Microsoft 365 Copilot mobile experience on iOS—which converts the app into a file preview and Copilot chat wrapper that redirects editing tasks to standalone Word, Excel, and PowerPoint apps—represents a deliberate shift in how the company structures mobile...

Microsoft has pushed generative AI squarely into the heart of Excel with a native =COPILOT(... formula that lets users type natural‑language prompts directly into cells, reference worksheet ranges for context, and receive live, spillable AI outputs that recalculate automatically as the source...

Microsoft has put generative AI directly into the cell grid: the new COPILOT function lets users type plain‑English prompts into Excel formulas and returns live, spillable outputs — summaries, classifications, tables and more — that update automatically as the underlying data changes. This...

Microsoft has quietly moved one of the most consequential AI experiments of the last year from a sidebar into the very fabric of Excel: the new COPILOT function lets users write plain‑language prompts directly in a cell and receive AI‑generated results that behave like any other formula in the...

Microsoft has quietly moved one of the most game‑changing ideas in AI — a conversational, generative assistant — from a sidebar into the heart of a spreadsheet, by introducing a native =COPILOT formula that runs Copilot prompts directly inside Excel cells and returns live, spillable outputs that...

Microsoft has quietly — and deliberately — taken the next step in turning Excel from a grid of formulas into a conversational interface by embedding a native =COPILOT function that lets users type natural-language prompts directly into cells and have generative AI return live, recalculating...

Excel’s new COPILOT function hands everyday spreadsheet users an AI-powered microscope and a blunt instrument at the same time: it can summarize, classify, extract, and generate structured outputs from free-text or tabular data with a single cell formula, but it also introduces new operational...

Microsoft has put a generative AI assistant where most knowledge workers spend the bulk of their time: directly into Excel’s grid with a new COPILOT function that lets Microsoft 365 Copilot run natural-language prompts inside individual cells and return multi-cell arrays, categories, summaries...

Microsoft is rolling a generative AI function directly into Excel’s calculation engine — a native formula called COPILOT that lets users pass natural‑language prompts and optional grid ranges to a cloud AI model and receive live, recalculating outputs inside cells, a capability that closely...

CISA’s latest update places three long‑standing and newly discovered flaws squarely in the crosshairs of enterprise defenders, adding CVE‑2013‑3893 (Internet Explorer), CVE‑2007‑0671 (Microsoft Excel), and CVE‑2025‑8088 (WinRAR) to the agency’s Known Exploited Vulnerabilities (KEV) Catalog on...

Microsoft’s Security Response Center has published an advisory listing CVE-2025-53739 — an Excel vulnerability described as “Access of resource using incompatible type (‘type confusion’)” that can lead to code execution when a crafted spreadsheet is processed by the desktop client. Background /...

Microsoft has confirmed a use‑after‑free vulnerability in Microsoft Excel (tracked as CVE‑2025‑53735) that can lead to local code execution when a crafted spreadsheet is opened — a serious document‑based attack vector that demands immediate attention from IT teams and security‑minded users...

Note: I checked the Microsoft Security Response Center (MSRC) entry you linked and reviewed public vulnerability feeds while preparing this article. The MSRC page for CVE-2025-53759 is the primary source for the vulnerability statement; I also cross‑checked public advisories and CISA summaries...

A heap‑based buffer overflow found in Microsoft Excel, tracked as CVE‑2025‑53741, has been published in Microsoft's Security Update Guide as a vulnerability that can allow an attacker to execute code on a victim machine when a crafted spreadsheet is opened; administrators and users should treat...

Microsoft’s newest Copilot integration puts a human-readable explanation of complex Excel formulas directly into the worksheet, translating opaque function tokens into plain‑language summaries, step‑by‑step breakdowns, and context-aware notes so users can understand, audit, and safely modify...
