I wrote my first piece of software on a Z-80 processor in high school. The landscape of technology has changed dramatically since then — but Excel, used properly, remains one of the most underrated tools in business.
What Most People Get Wrong
The typical Excel user knows how to SUM a column and maybe create a VLOOKUP. But Excel has an entire programming environment built in — Power Query, DAX, Power Pivot, VBA — that can automate months of manual work.
Defined Names: The Underused Superpower
At ExcelPatterns.com, I document one of Excel's most powerful and misunderstood features: Defined Names. When used correctly, they make complex formulas readable, maintainable, and dramatically easier to audit. A spreadsheet built with proper Named Ranges is a fundamentally different product than one built without them.
When Excel Isn't Enough
There comes a point in every company's growth where Excel breaks down. Usually it's around the time you have more than 2-3 people touching the same data, or when you're pulling from multiple source systems. That's when tools like Power BI, or a proper database layer, become essential. Knowing when you've hit that threshold is itself a valuable skill.
