Lesson

Budgets, Excel, and Sheets

Much office work lives in spreadsheets. AI is useful when it cleans data, cross-references tables, and creates budget drafts that a person can review.

  • Turn client requests into budget drafts.
  • Clean spreadsheets without losing traceability.
  • Create simple reports from CSV or Sheets.

Budget template

Terminal
Input:
- client message
- service catalog
- base rates
- standard terms

Output:
- needs summary
- budget line items
- assumptions used
- pending questions
- email text to send after review

Prompt for spreadsheets

Terminal
Analyze ventas.csv.
Do not modify the original file.
Create ventas_limpio.csv with:
- dates in ISO format
- amounts as numbers
- normalized categories
- duplicate rows separated into duplicados.csv
Then create informe.md with:
- monthly total
- top 5 products
- detected anomalies
- questions to review
Invoices, OCR, and Verifactu with Human ReviewConvert a bank statement to CSV without inventing transactions

How all courses connect

This is not a checklist. Start with the foundation, choose an outcome, and go deeper only when your project needs more control.
