Should You Still Be Using Excel to Run Your Business?

Increasingly, no. Not because Excel is weak, and not because it's manual, which is the reason you've probably been given. Excel was never the best tool for running a business. It was the fastest one to start. That was a real advantage and it's the one thing 2026 took away.

Here's what actually changed, and the part of it nobody selling you software will mention.

Excel's advantage was that starting cost nothing

Think about why the spreadsheet won in the first place. It was free. It opened instantly. Nobody had to be trained. No vendor could change it or raise the price on you. And every alternative wanted a project: a setup call, a migration, a month of getting it wrong.

So the trade was obvious. Excel was worse at almost everything and better at the only thing that mattered on a Tuesday, which was starting today.

That gap has closed. You can now describe the thing you want in plain language and get a working version back. Tools like Julius, Powerdrill and AnswerRocket take a question like "which products made the most money last quarter" and return charts and written summaries with no formulas and no code at all.

An afternoon, not a project. Which means Excel's one advantage is now just the normal state of everything.

Adding AI to Excel upgrades the wrong part

This is where most advice this year gets it backwards, so it's worth being precise.

Copilot is built into Excel and Gemini is built into Google Sheets, and Google put its AI features into standard Workspace plans at no extra cost back in January 2025. Both are genuinely good, and most owners have never opened either one. (Knack · GPT for Work)

But look at what they actually improve. They make it easier to ask questions of a file. Writing the formula, building the summary table, sorting by a column you had to create first.

That was never the expensive part.

The expensive part was always everything around the file, and AI inside the sheet leaves all of it exactly where it was. You still have one person's private copy. Nothing still happens on its own. And every single number in there still had to be typed by a human who remembered to type it.

Excel plus AI is a faster way to interrogate the same broken arrangement.

Three things a spreadsheet can't do, whatever you bolt on

1. Hold one version of the truth. The moment two people write into a file, you have two files. One is called "final". With AI on top you now get a confident answer computed from whichever copy happened to be open, which is worse than no answer, because nobody checks a chart.

2. Act. A spreadsheet will hold "invoice unpaid since March" perfectly and will never once do anything about it. AI can draft a beautiful chasing message. It can't know the invoice is unpaid unless something is actually watching that invoice. Writing was never the hard part. Noticing is.

3. Know what you didn't type. This is the one that decides everything.

Your spreadsheet isn't storing your business. It's storing your memory of your business.

Look at one row. A name, a number, a date. What it doesn't say is that this customer always pays late but always pays, that the price was a favour because his brother sent him, that the date is wrong because you wrote it on Sunday for a job that happened Thursday.

All of that is real, and all of it is in your head. It worked while you were the only reader, because you plus the file made a system. An AI reads the file and only the file. It cannot read your head, it won't tell you what's missing, and it will answer anyway.

Try it today, it takes ten minutes. Open your sheet, turn on the AI that's already inside it, ask it the hardest real question you have, then count what it got wrong. That list is worth more than any software comparison.

What you lose by leaving it another year

You don't lose the spreadsheet. You lose the history.

Take a salon running four years on one file. It has names and totals. No phone numbers for most people, dates for maybe half, no record of what service anyone actually had.

Point the best AI in the world at that file. It'll give you the total. It can't tell you who's due back, who quietly stopped coming, or who to send a message to, because none of it was ever written down. Four years of customers and nothing to work with.

AI multiplied the value of the data you recorded, and did nothing whatsoever for the data you didn't. That's the actual cost of another year, and it isn't a subscription fee.

And you don't have to guess what's missing. Ask it. Give the AI your file and ask what it needed and couldn't find. For most shops it comes back with the same three: a phone number, a date, and what the customer actually bought. Add those columns today, in the file you already have. It takes a minute and it's the only thing here that gets worse the longer you wait.

The trap on the other side

Don't read any of this as "go and subscribe to five AI tools."

Here's how that version goes. You get an AI tool for writing customer messages. Then one for the numbers. Then your booking app adds its own AI, so that's three. Each one holds a piece of the business and none of them talk to each other.

Six months later somebody asks how many customers came back last month, and the answer is spread across four places, exactly like before. You replaced a spreadsheet with a subscription and kept the problem.

We went through this recently: the useful question isn't how many features you get, it's how many places you have to look to know how today went.

There's also an honest catch with building your own. It's genuinely fast now, and what you build is yours to maintain. When it breaks in eight months, or the person who set it up leaves, that's your problem. Fast to start is not the same as cheap to keep.

What to do this month: rebuild it, with AI

Don't read more comparisons. Spend one afternoon trying to rebuild your spreadsheet in ChatGPT or Claude and you'll learn more than a month of research would tell you.

1. Take your real file to ChatGPT or Claude. Not a sample, the actual one. Upload it and say what the business is in two lines.
2. Ask it to build what you want to see. Something like: "This is my sales sheet for a barbershop. Build me a dashboard that shows which customers haven't come back in three months, what each one usually spends, and which service makes the most money." Then look at what comes back.
3. Count what it got wrong, and why. Almost always the answer is that the file didn't have what it needed. That list is your gap, and it's the brief for everything after.
4. Ask it to design the record you should have been keeping. "What fields would I need for you to answer that properly?" It'll tell you. That's more useful than any template.
5. Then decide what you want to own. Build it yourself and maintain it, or use something where the structure is already there.

Step 3 is the one that matters. Most owners expect to learn something about AI that afternoon, and what they actually learn is what they've been failing to write down for four years.

What we're building

Swarlet is business management software for the owner who is also the staff. One place for sales, stock, customers and invoicing, in Arabic and English, built for how business actually runs in the Gulf.

It replaces the spreadsheet rather than sitting next to it. That's the point. The structure is already there, so the customer record has a phone number field whether or not you remembered, the invoice knows it's unpaid, and the answer to "how did today go" is one place instead of a file you have to interrogate.

We're not open yet. If you've read this far and recognised your own file, join the waitlist and we'll bring you in early.

And if you already run more than one branch, you passed this line a while back. The spreadsheet question was settled the day you stopped being able to see both rooms at once.

Frequently asked questions

Should I still use Excel to run my small business in 2026? Increasingly, no. Excel's real advantage was never power, it was that starting cost nothing and took no setup. AI tools now build a working dashboard from a plain description in an afternoon, so that advantage has mostly gone.

Doesn't adding AI to Excel fix this? It fixes the easiest part. Copilot in Excel and Gemini in Google Sheets make asking questions simpler, but they don't give you a shared record, they don't make anything happen on its own, and they can't see what you never typed in.

Can AI really build me a dashboard without a developer? For a small business, usually yes. Tools like Julius, Powerdrill and AnswerRocket take a plain-language question and return charts and summaries with no formulas or code. The catch is that you then own and maintain the thing you built.

What can Excel never do, no matter what I add to it? Three things. Hold one version of the truth when two people are writing. Act on its own, like chasing an unpaid invoice. And know anything you didn't type into it.

What's the risk of staying on a spreadsheet another year? You lose the history, not the tool. Four years of names and totals with no phone numbers and no dates is four years no AI tool can do anything useful with, and you can't recover it.

Should I subscribe to several AI tools to replace my spreadsheet? That's the trap on the other side. One tool for messages, one for numbers, one inside the booking app, and six months later the answer to a simple question sits in four places instead of one. You've replaced a spreadsheet with a subscription and kept the problem.

What should I be recording that I probably am not? Ask the AI. Give it your file, ask what it needed and couldn't find, and it will tell you. For most shops it comes back with the same three: phone number, date, and what the customer actually bought.
