Microsoft’s spreadsheet story is no longer only about the desktop app. According to reporting from Windows Latest, Brian Jones, who leads Microsoft’s Excel Product Group, says Excel for the web session counts have grown tenfold over the last six years. That is a useful signal for IT departments, Microsoft 365 administrators, and Windows enthusiasts because it shows how quickly browser-based productivity habits are changing—even in a category where Google Sheets has long been seen as the natural web-first choice.

The practical takeaway is not that every organization should abandon desktop Excel. Rather, it is that Microsoft’s browser-first spreadsheet strategy has become a real operational option for more everyday work. If your users still think of Excel for the web as a limited viewer or emergency fallback, it may be time to reassess what it can do, where it fits, and how it should be governed.

Why the growth matters

A tenfold increase in sessions is not the same as a tenfold increase in licensed users, but it is still meaningful. Sessions indicate repeated use: people opening workbooks, editing data, collaborating, and keeping Excel active in the browser. For Microsoft, that suggests Excel for the web has moved beyond “good enough in a pinch” and into regular workflow territory.

The background is important. Windows Latest connects this growth to Microsoft’s broader cloud-first shift that accelerated around 2018, when the company reorganized engineering priorities around Azure, Office 365, and cloud services. That investment helped narrow the gap between web Office apps and their desktop equivalents. The result is a version of Excel that can now cover many common spreadsheet tasks without requiring a local Office install.

For IT teams, that has several implications. Browser-based Excel can reduce dependency on full desktop deployments for occasional users, support managed access from shared or temporary devices, and simplify collaboration through OneDrive and SharePoint. It also gives organizations a more credible Microsoft-native alternative when business units default to Google Sheets simply because it is easy to open in a browser.

Google Sheets still owns the web-first perception

Microsoft’s challenge is partly technical, but it is also about perception. Google Sheets is widely understood as free, fast, and browser-native. Excel for the web is also available free with a Microsoft account, yet many users do not know that. In business environments, the awareness gap can be just as important as the feature gap.

That matters because user behavior often starts with the path of least resistance. If someone needs a quick table, a lightweight project tracker, or a shared list, they may choose the tool they can open fastest and explain to colleagues most easily. Microsoft has improved Excel in the browser, but it still has to make that experience feel obvious.

For administrators, this is an opportunity to provide clearer guidance. If your organization standardizes on Microsoft 365, show users when Excel for the web is the preferred collaboration tool, where files should be stored, and how sharing should be handled. Without that guidance, users may scatter spreadsheets across personal Google accounts, unmanaged cloud drives, or email attachments.

Where Excel for the web fits today

Excel for the web is strongest for lightweight to moderate workbook editing, review, co-authoring, simple analysis, formatting, and sharing. It is particularly useful when users need to make quick changes from a managed browser session or collaborate on a workbook stored in OneDrive or SharePoint.

Desktop Excel still matters for heavy-duty work. Complex models, advanced add-ins, large datasets, Power Query workflows, VBA-heavy workbooks, and specialized finance operations may still require the Windows desktop version. The best strategy is not to frame web Excel and desktop Excel as competitors. Treat them as two access layers for the same spreadsheet platform.

A practical policy could look like this: use Excel for the web for shared operational trackers, review cycles, simple reporting, and quick edits; use desktop Excel for complex modeling, automation, add-ins, or performance-sensitive files. That keeps users productive without pretending the browser can replace every advanced scenario.

Copilot raises the stakes

The Windows Latest report also points to Microsoft’s next big bet: AI in Excel. Microsoft has been building Copilot features for finance and analytics workflows, including more structured ways to let AI assist with modeling tasks. If Microsoft can make AI-generated spreadsheet changes transparent, auditable, and easy to review, Excel could become a more powerful decision-support environment.

But there is a trust problem. Spreadsheet users care deeply about where numbers come from, which formulas changed, and whether an automated suggestion can be verified. A Copilot feature that saves time but obscures logic will struggle in serious business settings. IT leaders should evaluate AI spreadsheet features with the same discipline they apply to macros, add-ins, and data connectors: who can use them, what data they can access, how outputs are reviewed, and whether sensitive information leaves approved boundaries.

There is also a user-experience lesson. Microsoft has faced criticism for placing Copilot entry points too aggressively inside Office apps. If AI appears to interrupt work or cover useful spreadsheet space, users may reject it even if the underlying feature is valuable. Adoption will depend on control, clarity, and trust—not just visibility.

Recommendations for Microsoft 365 administrators

Start by checking how your organization actually uses Excel across desktop, browser, and mobile. Microsoft 365 usage reports, OneDrive activity, and support tickets can reveal whether users are already moving workbook collaboration into the browser.

Next, update internal documentation. Many employees still do not know when Excel for the web is appropriate, whether it is approved, or how it differs from desktop Excel. A short internal guide can prevent tool sprawl and reduce confusion.

Then review sharing and data-loss policies. Browser-based spreadsheets are convenient, but convenience should not bypass governance. Confirm that sensitivity labels, conditional access, external sharing rules, and retention settings apply consistently to Excel files stored in Microsoft 365.

Finally, pilot Copilot in Excel carefully. Choose teams with clear workflows, measurable outcomes, and strong review habits. Finance, operations, and reporting teams may benefit, but they also need guardrails. Track whether Copilot reduces repetitive work, improves formula discovery, or simply adds another layer of checking.

Bottom line

Excel for the web’s reported growth shows that Microsoft’s long cloud investment is paying off in everyday productivity, not just in Azure revenue. Google Sheets remains a powerful competitor because it owns the mental model of fast, free browser spreadsheets. But Microsoft now has a stronger answer than many users realize.

For Windows and Microsoft 365 environments, the smart move is to treat Excel for the web as a mainstream collaboration option while keeping desktop Excel available for advanced work. The organizations that benefit most will be those that combine user education, governance, and careful AI adoption instead of letting spreadsheet habits evolve unmanaged.
