ChatGPT, Claude, and Copilot can do in sixty seconds what currently takes you three hours. The problem is not the tool. The problem is that nobody taught you how to actually use it.
If your relationship with AI is typing a quick question and hoping for something useful, you are getting roughly ten percent of what these tools can deliver. The other ninety percent comes from knowing how to prompt properly — and that is a skill, not a guess, with patterns that work every single time once you know them.
From Spreadsheets to AI Tools is a practical, no-nonsense guide for Excel professionals who want to use AI seriously: to write reports faster, clean data more systematically, draft emails in seconds, and automate the repetitive thinking-work that fills up every working week.
Every technique in this book is taught through the lens of work you already do. Not abstract "AI use cases" — actual monthly commentaries, actual customer emails, actual formula debugging, actual data quality audits. You will not finish this book knowing AI trivia. You will finish it with reusable prompt systems running in your actual job.

WHY PROMPT ENGINEERING IS THE SKILL OF 2025
The gap between a mediocre AI output and an exceptional one is almost never the model. It is the prompt. The same AI tool that gives a generic, unusable answer to a vague question will produce a polished, board-ready management commentary when given the right structure, the right context, and the right constraints.
This is the highest-leverage skill gap in business today: the people who know how to prompt well are getting a genuine 5 to 10x productivity multiplier on writing, analysis, and reporting tasks. The people who do not are still doing it the slow way, unaware of how much time they are leaving on the table every single week.
No AI experience required. No technical background needed. If you can describe a task clearly to a colleague, you can learn to prompt an AI model to do it for you — this book shows you exactly how.
