Where Excel shines, where it's dangerously out of its depth, and when it's time to graduate to purpose-built systems.
If I asked you who your best friends were, would you know? What if I said your best friends were the people, places or things you spend the most time with? Would your answer change?
For me, my answer would probably be some combination of the following: my family, my mattress, my socks, and Excel. And I don't think I am alone. Unless you are carefree and barefoot. Which is totally a respectable lifestyle.
Why is Excel such a good friend? It is there for us when we need it across the board. Big life decisions? Excel. Vacation planning? Excel. Personal Budget? Excel. Online dating decision tree? Excel. Wedding guest list? Excel.
And if you work in a company of pretty much any size, you probably use it a ton for work too. In fact, small businesses are very often BFF with Excel across lots of core processes and decisions. ERP? Excel. Org planning? Excel. Planning tool? Excel. Workflow? Outlook (and Excel).
But chances are if you have worked at a larger company, you have used more than just Excel.
Excel owes its dominance to three superpowers:
These perks make Excel irresistible for small businesses. But they also create an environment where Excel gets asked to do things it was never designed for (like being an ERP or a CRM or a workflow engine or the central nervous system of a $50M company).
Let's explore the difference between using Excel because it's great and using Excel because you haven't yet discovered the pain of not using a real system.
There are annual Excel competitions for speedy masters of Excel, including the Microsoft Excel World Championship (MEWC) and the Microsoft Excel Collegiate Challenge (MECC). It's an eSports competition where participants solve unusual tasks and logic puzzles to earn glory. VLOOKUP sports events rock.
A category-by-category comparison of where Excel fits and where it falls short.
ERP systems manage transactions, inventory, purchasing, manufacturing, sales orders, and accounting. Excel manages cells.
| ERP Fit | Excel Strength | Excel Weakness | ERP Advantage |
|---|---|---|---|
| Transaction accuracy | Great for small volume | Manual entry → errors | Validations, workflows |
| Multi-user access | Works in theory | Version conflicts | Role-based access |
| Inventory mgmt | OK for low SKU | Fails with complexity | Real-time updates |
| Audit & controls | None | Wild West | Compliance support |
Planning is where Excel is both a friend and an enemy. A Frenemy.
| Planning Fit | Excel Strength | Excel Weakness | Planning Tool Advantage |
|---|---|---|---|
| Collaboration | One owner | Many contributors | Concurrent & sequenced workflows |
| Data integration | Manual refresh is OK | Requires automation | Automated system connections |
| Governance | None needed | Audit needed | User permissions |
| Scale | Low data volume | Large dimensionality | Big Data processing |
Excel is used for BI more than any BI tool ever created. That doesn't mean it should be the BI tool when you are trying to democratize data or digitally transform.
| BI Fit | Excel Strength | Excel Weakness | BI Tool Strength |
|---|---|---|---|
| Self-service | Very high | Can become chaos | Governed self-service |
| Visuals | Adequate | Outdated, inconsistent | Modern UI |
| Data refresh | Manual/slow | Breaks often | Automated |
| Scalability | Limited | Crashes >1M rows | Big data handling |
Artists use Excel as a canvas, not just a calculator. By carefully coloring cells, creators have reproduced detailed pixel-style works, including the Mona Lisa, entirely within spreadsheets. In Japan, Tatsuo Horiuchi became famous for creating full landscape paintings using Excel's drawing tools instead of traditional art software.
Yes, companies do this. No, they probably shouldn't.
Excel is not a workflow engine. We try to make it act like one, flagging things that need attention with color-coding and attached to emails. But it's manual and scrappy.
Master Data Management is about creating a reliable, governed, single source of truth for critical business entities and domains (customers, products, vendors, employees, chart of accounts, and more). Excel can store these things, but storing data is not the same as managing data.
| MDM Requirement | Excel Strength | Excel Limitation | MDM Tool Advantage |
|---|---|---|---|
| Data validation | Basic filters | No rule engine | Automated rules & scoring |
| Golden record creation | Manual deduping | Error-prone | Matching & survivorship |
| Hierarchy mgmt | Manual grouping | Breaks easily | Structured hierarchies |
| Security workflows | None | No approvals | Stewardship & governance |
| Integration | CSV imports/exports | No real-time sync | APIs & pipelines |
Summary scorecard (1-5 scale) for growing companies.
* Good/Fair for small teams only. Fit degrades rapidly with scale.
If any of these apply, Excel has done its job and you should help it out by getting a solution that can do what it can't.
Excel is one of the greatest business tools ever built. It's flexible, powerful, and accessible. It can prototype nearly anything. But it's not a scalable substitute for purpose-built systems.
In other words: Excel is the perfect place to begin and use, but rarely the place to put all your data process needs.
