The Nightmare Excel File Only Juan Understands
Every business has one. That Excel file with macros nobody understands, formulas that mysteriously break and that only Juan, who has already resigned, knew how to manage.
It is time to let it go.
Why Excel Does Not Scale
Do not misunderstand me. Excel is an incredible tool. But it has limits:
❌ One file = one user at a time ❌ Versions called "Final_v3_definitely_final_this_time.xlsx" ❌ Formulas that break when someone edits ❌ No reliable change history ❌ Difficult mobile access
The Alternative: Google Sheets
Google Sheets is more than "Excel online". It is a collaborative tool with superpowers:
✅ Multiple simultaneous users ✅ Automatic change history ✅ Access from any device ✅ Integrations with hundreds of tools ✅ Automation without macros
Your First Automation
Let us create a simple but powerful automation: an automatic notification when a row is added.
Scenario: You have an orders sheet. You want to receive an email whenever a new order arrives.
Tools: Google Sheets + Google Apps Script (included, free)
Steps:
- Open your sheet in Google Sheets
- Go to Extensions > Apps Script
- Copy this code:
function onEdit(e) {
var sheet = e.source.getActiveSheet();
if (sheet.getName() == "Pedidos") {
MailApp.sendEmail("tu@email.com", "Nuevo Pedido", "Revisa la hoja de pedidos");
}
}
- Save and authorise
- Done!
