In this article, we’ll trace the untold story of how Excel, often dismissed as a humble desktop spreadsheet, quietly scaled to enterprise level—and then global level—decades ago. This is not the story you’ve been told. It has little to do with Google Sheets or “Excel on the web.” To truly understand Excel’s transformation, we need to go back. Way back.
The Origins: A Fragmented World of Isolated Software
In the 1980s, the personal computer revolution introduced business users to a new world of productivity. But early PCs were restricted in a major way: they could only run one application at a time. You opened your spreadsheet, worked on it, closed it, and then loaded your word processor to type up a report.
Meanwhile, there was a gold rush in software tailored for specific business functions—stock control, payroll, sales tracking, etc. These programs were siloed. Each came bundled with its own data. A customer database in one tool couldn’t be accessed by another. The term “data integration” didn’t yet exist for most businesses.
If you wanted your accounting system to talk to your HR system, you had to get creative. The “export-import” process usually meant printing out data on those green-striped dot matrix sheets and manually re-entering it into the next system—or, if you were clever, you might save the data to a floppy disk and walk it across the office.
The Breakthrough: Networks and Windows Change the Game
Around the late 1980s, two pivotal innovations changed everything.
- Networking (Ethernet): PCs could now be physically connected. This enabled machines to “see” each other and share data without manual transfer.
- Windows: Suddenly, you could run multiple applications on the same machine simultaneously, and the operating system could handle far more internal memory.
These changes laid the foundation for a radical new architectural paradigm: client-server computing. In this model, data could be separated from the application that used it—and centrally stored.
This was the birth of Enterprise Resource Planning (ERP). If business processes are really just transformations of data—orders being placed, shipments being fulfilled, invoices being sent—then storing all that data centrally allows for massive gains in efficiency, accuracy, and visibility.
Enter Microsoft Office—and Excel’s Quiet Evolution
Microsoft didn’t miss this trend. They saw what SAP, Oracle, and others were doing and responded with something that many still underestimate: Microsoft Office.
It wasn’t just a bundle of Word, Excel, PowerPoint, and Access. It was a technically engineered ecosystem. Microsoft made these tools integratable. They didn’t just work side by side—they could work together.
This culminated in a pivotal moment: the December 1993 DevCast, a three-hour enterprise technical briefing. In that presentation, a young Satya Nadella demonstrated how Excel could read from and write to a centralized database. His example? Automatically triggering stock reorders based on inventory levels—data stored in a relational database, not in Excel.
It was ERP-style process automation, but inside Excel.
ActiveX Data Objects: The Missing Link
By 1997, this capability became mainstream with the release of Office 97 and the introduction of ADO (ActiveX Data Objects). ADO allowed Excel, Word, and Access to connect directly to enterprise databases—SQL Server, Access, Oracle, you name it.
Each Office app represented a familiar business paradigm:
- Excel: analysis and modeling
- Word: documentation and reporting
- PowerPoint: presentation
- Access: structured data storage and retrieval
ADO was the glue. It enabled these paradigms to work together, transforming Office from a set of tools into a powerful platform for office automation solutions.
This was Excel going enterprise.
From Enterprise to Global: The Cloud Multiplier
Now fast forward ten years. The cloud becomes mainstream. What changes?
Very little—architecturally speaking.
What was once an Access database on a shared company drive could now sit on a cloud server. And any Excel workbook—anywhere in the world—could connect to it. The client-server architecture hadn’t changed. Only the location of the server had.
Your Excel spreadsheet is now a global application.
Today, this architecture can include:
- Excel desktop (Windows or Mac)
- Excel for web
- Google Sheets
- Power Apps
- Office Scripts
- Mobile apps
All of them can read from and write to the same centralized data store. That’s a hub-and-spoke model—a modern rebrand of client-server. The spokes are the apps. The hub is the database.
The result? A single source of truth, enterprise-wide workflows, and global reach.
So Why Don’t More People Know This?
That’s the punchline.
Most people don’t know this history, don’t understand what’s possible, and don’t teach it. For 30 years, Excel has had enterprise-grade capability. But most Excel education focuses on standalone workbooks, manual processes, and flashy formulas.
“Triple your pay with Excel” isn’t just a slogan. It’s a reflection of what’s possible when you unlock this capability. Businesses are filled with inefficient, fragmented processes simply because nobody ever told them Excel could do this. When you show them—even once—they don’t forget it.
Summary: The Story We Forgot
Excel didn’t “go enterprise” last year. It did it in 1993.
Excel didn’t “go cloud” in 2020. It did it in 2003—when the cloud just meant “a remote drive.”
And Excel’s global capabilities aren’t about Google Sheets. They’re about architecture.
If you want to reimagine your future with Excel—financially, professionally, and strategically—it starts with understanding how we got here.
This is one of the foundational lessons in the How We Got Here series.
