Why Excel Still Matters in the Age of Artificial Intelligence

Excel has been declared obsolete by some new technology roughly once a decade since the 1990s — first databases, then business intelligence tools, then no-code platforms, and now AI. It's still the tool almost every finance function in the world reaches for first. That persistence isn't inertia. It's worth taking seriously as a signal.

Fact: Excel remains the dominant tool for financial modelling, budgeting and ad hoc analysis across small businesses and large enterprises alike, despite decades of purpose-built alternatives. Most accountants, analysts and business owners can build a working model in Excel faster than they could specify requirements for a custom tool.

Why it hasn't been displaced

The honest answer is flexibility. A spreadsheet imposes almost no structure — you can build exactly the model your business needs, reshape it in minutes when circumstances change, and hand it to almost anyone else in finance and know they can open it and understand it. Purpose-built software is usually better at one specific job and worse at everything else; Excel is mediocre at nothing and expert at nothing, which turns out to be exactly the tradeoff most ad hoc financial work needs.

Where AI actually fits in

This is where the "AI replaces Excel" framing misunderstands both tools. AI is good at generating a first draft, explaining a formula, catching an error in logic, or turning a plain-language description into a working structure. It is not good at being the persistent, auditable, shareable artefact that a finance team actually works from day to day — that's what a spreadsheet is for. The realistic near-term shift isn't "AI replaces Excel," it's "AI becomes the thing that helps you build, audit and query the spreadsheet," through natural-language formula generation, automated error-checking, and models that can explain what a decades-old inherited spreadsheet is actually doing.

Analysis: the businesses getting real value from this pairing right now aren't the ones replacing their models with chatbots. They're the ones using AI to speed up the parts of spreadsheet work that were always tedious — writing a gnarly nested formula, reconciling two versions of a model, documenting what a sheet does for the next person who inherits it — while keeping the spreadsheet itself as the source of truth.

Opinion: Excel's staying power is a useful reminder that "which tool wins" is rarely decided by which is most advanced. It's decided by which imposes the least friction on the person actually doing the work. AI is a genuine step change in capability, but it's an addition to that toolkit, not a replacement for the one tool finance has never quite managed to walk away from.
