How to Write Excel Formulas with AI

Quick verdict
Short version: buy at the Best overall level, roughly $0, and put the difference towards the thing you will actually use it for. Higher tiers exist for specific constraints, not for better everyday results.
We deliberately avoid naming specific models — they change every season, while the trade-offs below do not.

What actually matters
Ignore the marketing for a moment. Across this category the same questions separate the options people keep from the ones that end up in a drawer.
- What the AI actually does. separate the scripted demo from what it does on your own input. Red flag: a demo video with cuts at every step.Subscription traps — check the cancellation path before you subscribe. Treat cancelling requires an email to support as the sign a spec sheet is hiding something.Data and privacy — know what leaves your device and who keeps it. Treat a policy that allows training on your uploads as the sign a spec sheet is hiding something.Free tier versus paywall matters more than it looks: work out where the paywall actually starts. And a trial that converts silently into a subscription is a warning, not a detail.
If you only remember one thing: separate the scripted demo from what it does on your own input.
The tiers worth considering
Each tier below is a real position in the market, not a marketing invention. The prices overlap more than you would expect.
Best overall
Think of this as the default answer for most people. It is not the cheapest and not the most feature-heavy, but it gets the fundamentals right and rarely needs defending. Upgrade later if you hit a limit; you almost certainly will not regret starting here.
- Holds up under regular use
- Fewest surprises overall
- Widely reviewed, so parts and alternatives are easy to find
Trade-off: pricier than the alternatives, and the gap rarely shows on a spec sheet.
Best free tier
This is the balanced choice, and balance is underrated. The details that annoy people in cheaper options have been dealt with rather than hidden. Move up a tier only when one of your constraints is genuinely hard, not when a review talks you into it.
- Lowest cost that still makes sense
- Covers the essentials well
- Cheap to replace if it breaks
Trade-off: the cheapest option still worth owning, but not the nicest to use.
The power-user pick
This is the version we would buy ourselves, and the reason is boring. It is the option that generates the fewest regret reports once the return window closes. It is the tier most people should own, and the fact that it is not exciting is the point.
- Long service life
- Better materials and better support
- Usually keeps its resale value
Trade-off: more than most people need — buy it only if you will use it weekly.
The lightweight option
This is the tier we would recommend without a caveat to a friend. The details that annoy people in cheaper options have been dealt with rather than hidden. It is the tier most people should own, and the fact that it is not exciting is the point.
- Takes up noticeably less space
- Easy to move or travel with
- Set-up is measured in minutes
Trade-off: the compact version always costs a little more per unit of performance.
Best for small teams
This is the tier we would recommend without a caveat to a friend. Everything about it is aimed at being used hard rather than admired on a shelf. Move up a tier only when one of your constraints is genuinely hard, not when a review talks you into it.
- Quickest to get started with
- Forgiving of beginner mistakes
- Plenty of tutorials and community help
Trade-off: simple by design, which also means it stops short of advanced features.
How we approach this guide
Every section is written to be checked. If you think our weighting is wrong, the criteria are listed in plain language so you can re-rank them for your own situation and reach a different — and equally valid — conclusion.
Frequently asked questions
Is how to write excel formulas with ai worth it in 2026?
For most people, yes — but only at the tier that matches your actual use. The mistake is buying the top tier on day one, then dropping the habit. Start one tier lower than you think you need, and upgrade when you hit the limit rather than before.
How do I compare two tools fairly?
Run the same real task through both, time it, and note the one thing each made you do manually. Features rarely decide it; friction does.
Is annual billing worth the discount?
Only if you have already used it for a full month. Annual discounts are large precisely because a lot of people stop after three weeks.
Do I need a team plan?
Only when two people genuinely need the same workspace. Team plans are usually the worst value for solo users.
Can I get away with the free plan?
For light, occasional use, often yes. The free tier usually breaks down at export quality, seat count or usage limits — so check those three before deciding to pay.
Bottom line
Come back to this page in three months and re-read the criteria. Your constraint will have changed, and so will the right answer. The trade-offs will not have moved.
