Moving from Excel to business software: when it's worth it for a solo business and how to move your data

Almost everyone starts with a spreadsheet. It's free, it opens anywhere and it does exactly what you tell it to. The trouble comes later, when the spreadsheet has to do things spreadsheets don't do: remind you of a deadline, match a payment to the right client, work properly on your phone.

Most guides on this switch are written for companies, with departments and consultants. When you work on your own the math is simpler, and you can get it done in an afternoon.

When the spreadsheet stops being enough

The same signs come up again and again.

The same data lives in two places. A client is in the clients sheet and also in the invoices sheet, with two different addresses, and you don't know which one is right.

A formula broke and you didn't notice. A row added outside the range of a sum, a number typed by hand over a formula: the total is wrong for weeks and nothing tells you.

You're the one who remembers deadlines. The sheet knows the client has to pay on the 30th, but it won't tell you. You have to open it, and remember to open it.

You don't use it on your phone. A sheet with twelve columns on a six-inch screen is hard to read and worse to edit, so you log the day's expenses in the evening, if you remember them.

Versions multiply. "Accounts 2026", "Accounts 2026 final", "Accounts 2026 final partner". If two of you work on it, sooner or later one overwrites the other's work.

If you recognise at least three of these, the spreadsheet is costing you more time than it saves.

When it's perfectly fine

With a single project, a handful of transactions a month and no deadlines to track, a well-built spreadsheet is more than enough. There's no reason to switch tools on principle. Switch when the time you spend keeping it in order is more than the time you spend using it.

How to move your data in one afternoon

The first step is deciding what to bring over. Not everything: active clients, products you're selling, this year's transactions and open deadlines. Past years stay as an archive, in a read-only file you can always reopen.

Then export to CSV, the format every business tool can read:

• in Excel, use "Save As" and pick "CSV UTF-8": with UTF-8, accented letters come through intact;
• in Google Sheets, go to "File", "Download", "Comma-separated values";
• in Notion, open the database menu, choose "Export" and pick CSV.

One technical detail worth knowing: Excel set to Italian, and to some other European languages, separates CSV columns with a semicolon instead of a comma. Most programs detect this on their own, but if every column ends up squeezed into one on import, that's almost always the reason.

Clean up before you import

Ten minutes of cleanup save an hour of fixes later. Before importing, check that your sheet has:

• a single header row, with no titles or notes above it;
• every date in the same format, for example 25/08/2026;
• amounts without the euro sign and with a consistent decimal separator;
• no merged cells, no total rows in the middle, no empty rows;
• one spelling per category, not "Shipping and packaging" in one cell and "shipping" in another.

Then import a single month and compare the totals with the ones in your sheet. If they match, import the rest. If they don't, the difference is almost always a badly written date or an amount with a dot where there should be a comma, or the other way round.

The month after

The biggest risk isn't losing data. It's using two tools at once. From the day you import, record everything in the new software only and leave the spreadsheet read-only. After a month of new numbers, you won't need the old file except to look back.

Hustlo imports CSV files from your bank, PayPal and Stripe, plus product and order files from Shopify, WooCommerce and Etsy. Whatever tool you choose, the method is the same: a little and clean, a one-month trial, then a single place to write things down.
