Free — and nothing leaves your browser

The file everything runs on has outgrown itself.

It started as a spreadsheet. It quietly became the system the business depends on. Drop it in and we will read it — here, on your own machine — and tell you plainly what it is carrying, and what could carry it instead.

Recognition

You already know which file this is.

It has a tab nobody dares touch, a column somebody added in a hurry, and one person who really understands it. It has also kept the business running for years, which is more than most software manages.

“If Susan takes two weeks off in August, nobody knows how to invoice the European accounts.”

The spreadsheet

What the spreadsheet needs on it

Use the workbook the business already runs on. One header row, with a name on each column, and the lists you already keep. A messy file is fine. There is no special template.

Who you work for

Customers, clients, patients, tenants, or donors. A name on each row is enough to start.

The work

Jobs, orders, matters, bookings, or cases. Use the word your business already uses.

The money

Invoices, payments, what you are owed, and what you owe. Dates help.

Who does it

The person responsible, if that list lives in the same file.

How it works

Three steps, about a minute.

01

Drop the file

Drag in the workbook the business actually runs on. It needs a header row and the lists you already keep: customers, the work, and the money. It stays on your machine — there is no upload.

Local file buffer allocated
02

We read it here

Sheets, formulas, dates, the shape of the thing. All of it happens inside your browser tab.

WebAssembly parsing cells
03

See what you would gain

A plain read of what the file is carrying today, and what could be carrying it for you instead.

Zero network transfer required
What changes

The manual parts stop being manual.

Nothing is taken away and nothing is thrown out. Your spreadsheet keeps working exactly as it does now. The difference is what stops landing on your desk.

Privacy guaranteed

Your file never leaves your computer.

The Spreadsheet X-ray is code that runs inside your own browser tab. Your workbook is not uploaded, not stored, and never seen by us. The only thing that can cross the network is a short summary — counts and totals — and only if you choose to send it.

Questions

Questions people ask first

Is my spreadsheet uploaded anywhere?

No. The file is read by code running inside your own browser tab. It never travels to us, we never store it, and we could not show it to anyone if we wanted to. The only thing that can cross the network is a short summary you choose to send us — counts and totals, never your data.

What kinds of files can it read?

Excel workbooks (.xlsx, .xlsm), older .xls files, and CSVs. Large files are fine; the read happens on your own machine, so the limit is your computer, not our server.

What does the spreadsheet need on it?

The workbook you already run the business on. One header row, then the lists you keep: who you work for, the work itself (jobs, orders, matters, bookings), and the money (invoices, payments, what you are owed). Add who does the work if that list is in the same file. A messy file is fine. There is no template to fill in.

Do I have to stop using my spreadsheet?

No, and we would not suggest it. Your spreadsheet keeps working exactly as it does today. Anything built afterwards sits alongside it and takes over the parts that are costing you time.

Is this an audit? Will it tell me what I did wrong?

No. It is a read, not a verdict. That file got the business to where it is, which is the opposite of a mistake. We show what it is carrying now that it was never built to carry.

Who is it for?

Owners and office managers of businesses with roughly five to eighty people — law firms, medical practices, builders, wholesalers, transport companies — where one spreadsheet has quietly become the system of record.

What does it cost?

The X-ray is free. The Monday Number is $29 a month. The Spine is $49, $99 or $199 a month depending on how many sheets it runs, with unlimited users on every plan. Ask Your Business is $19 a month, and it is included with Spine Full. The Business Report, Run the business, and the Inbox assistant are part of Outgrown; the price for each is set when it goes on sale. Cancel anytime. Paid plans open soon — early access gets you in first.

What do the paid products actually do?

The Monday Number sends five figures every Monday: cash, owed to you, owed by you, sales in the last seven days, and what falls due this week, each with one sentence of what it means. The Spine turns the same spreadsheet into one shared system: who changed what, jobs on a board, forms and reminders, while the spreadsheet keeps working. Ask Your Business answers a question about your own figures and says where the answer came from. The Business Report is the monthly written note. Run the business is customers, jobs, quotes, invoices, time and documents. The Inbox assistant drafts replies for you to approve and send yourself.
