Before you start the course, download the exercise files using the link in the Resources section below this lecture. The files are provided as a single zip archive — make sure you unzip the folder before opening any of the workbooks, as Excel may not open files correctly directly from a zip file. Each section of the course has its own subfolder, and the workbook for each lesson matches exactly what you will see on screen.

This course contains the use of artificial intelligence. AI tools are used in the production of this course, including AI-assisted speech delivery based on the instructor's own voice. All content, demonstrations, workbooks, and prompts have been personally designed, reviewed, and verified by the instructor to ensure accuracy and practical value.
What if you could have an expert Excel consultant sitting beside you every time you opened a spreadsheet?
That's exactly what Claude AI gives you. This course teaches you to work with Claude as a genuine productivity partner — not just to ask it simple questions, but to delegate entire workflows, automate repetitive tasks, and produce professional-grade output in a fraction of the time.
Everything you need is provided
Every lesson comes with the exact workbook used in the recording, all supporting datasets and documents, and the complete prompts used to produce every result on screen. Open the file, run the prompt, see it work — then adapt it to your own data. There's no guesswork and no gap between what you see demonstrated and what you can replicate immediately.
With Claude AI, you don't need to love Excel to get great results from it
Even if formulas make your eyes glaze over, VBA sounds like a foreign language, and you've always felt like everyone else just gets spreadsheets — this course is designed for you. Claude handles the syntax, the function arguments and the code. Your job is to describe what you want. The course teaches you exactly how to do that clearly and consistently, so you get the right result first time rather than the fifth.
What you'll work through
Formulas and functions — XLOOKUP, SUMIFS, dynamic arrays, nested logic and batch deployment across entire datasets
Formatting and presentation — typography, number formats, conditional formatting and chart customisation to board-ready standard
Pivot tables and data tools — source data hygiene, aggregation, layout, sorting, filtering and management reporting output

Practical from the first lesson
Every module was designed around real business scenarios — not toy examples. The workbooks, datasets and exercises reflect the kind of spreadsheet work that actually lands on your desk. The hands-on approach means you're practising on realistic data from the first lesson.
By the end of this course you won't just know more Excel. You'll work differently — faster, more confidently, and with an AI that handles the execution while you focus on the decisions.
