Tired of generic ChatGPT responses that miss the mark? Want AI that actually gets your tone, your tasks, and your workflow? This is the book for you.
In Train Your GPT, bestselling author and Excel legend Bill Jelen (a.k.a. MrExcel) takes you inside the world of Custom GPTs — the powerful, personalized AI tools you can train to write like you, work like you, and think like a trusted assistant. No coding required.
With humor, clarity, and hands-on guidance, Jelen shows how to:
• Build GPTs that follow your instructions every time
• Upload files to give your GPT real context (and a real personality)
• Analyze and improve your GPTs with feedback loops
• Integrate GPTs into Microsoft Copilot Studio and everyday apps
• Scale your content creation, automate repetitive tasks, and get more done
Plus, you’ll get real examples, behind-the-scenes conversations, and stories from the “ISPRIME incident” to the Groundhog Day dinner party — because this isn’t just another tech manual. It’s a fun, practical guide for real people using AI in real life.
Whether you're a content creator, teacher, consultant, or spreadsheet wizard, Train Your GPT will help you turn AI from a curiosity into a career-changing tool.
