From Excel to an app

The spreadsheet that can't cope any more, as an app made for you.

If your business runs on a sheet only one person understands, I turn it into a simple app that runs on your computer. And you can still take your data with you.

Portrait of Luís Agostinho.

I'm Luís Agostinho, in Lisbon, and I work with you: you always talk to me.

Three made-up sheets. Yours will differ: what changes is what the app shows you.

Already done

A studio swapped a sheet per student for an app.

An offline app that replaced a studio's Excel workflow: plans, loads and a live class board on the TV.

Sound familiar?

What you can't stand about the sheet, and what changes.

final_v3_this_time_for_real.xlsx

One version, always the current one, where the team uses it.

Only one person understands the sheet

The app shows its users what to do, with no manual and no hidden formulas.

Values typed by hand, errors nobody sees

Fields check what is typed and the app does the sums.

Hours spent maintaining the sheet instead of working

What repeated every week becomes one click.

You don't lose your Excel

In and out: your data is never locked in.

  • I import your sheet with a preview and a backup before touching anything.
  • You export whenever you like back to Excel. If you ever change your mind, you take everything.
  • It runs on your computer with no need for the internet.
  • You use both side by side until you trust the app. Only then do you let go of the sheet.
What the sheet costs you

Do the maths with your own numbers.

I only count the time you spend maintaining the sheet. I don't estimate errors or other costs.

Time spent updating, fixing and merging the sheet.
Use what you pay per hour, or what your time is worth.

Fill in the hours, people and weeks to see the result.

How it works

Five steps, and the sheet only goes when you want it to.

  1. A talk, and a map of the sheet

    We look at how you use it today, who touches it and where it hurts. It ends up in a short document, in plain words.

  2. Your sheet, already in the app

    I import your real sheet and show you your own data in the first version, so you react to something yours.

  3. You use both in parallel

    The sheet keeps working until the app earns your trust. No leaps in the dark.

  4. You switch

    You use only the app. I make a backup first and the original sheet stays safe.

  5. Handover and follow-up

    A written guide for your team, inside the app, and afterwards I'm available for whatever comes up.

Questions

What people usually ask me.

Do I need to install anything?

The app runs on your computer. We work out together, at the start, what you need to get it running.

Can I still take my data with me?

Yes. Your data always stays portable: you can take it with you whenever you want.

Where does my data live?

Where you prefer. We agree with you where the project's data lives.

Contact

Tell me about your sheet.

A few lines are enough: what it does, who uses it and what costs you most. I reply by the next business day and, after we talk, I send you a written quote.

Please don't send the sheet here. We'll agree the best way when we talk.

Need a website instead? See the website work

For example: we manage a guesthouse's bookings in a sheet and waste time merging versions.

I use your details only to reply to this message. See the privacy page.

I reply by the next working day.
