Six days. Six Excel functions. One very hungry dog.
The Full Stack Modeller Excel Function Challenge is a six-day series of free workbooks that will sharpen the way you use Excel. Each day, a new function. Each workbook, eight levels.
Join the challengeA week of Excel, one function at a time.
Each day for six days, a new workbook lands in your Full Stack Modeller account. Each one is built around a single Excel function, and each has eight levels that start gently and get harder as you go.
It's free. It's designed to be fun. And by the end of the week you'll have spent serious time with the functions that do most of the heavy lifting in real modelling work.
Five of the six are dynamic array functions, the biggest shift in how Excel works in the last decade. The sixth is a classic that still earns its place every day.
Stick with it to the end of the week and there's a bonus: a free Excel fundamentals course, and if you share your feedback, a free month of Full Stack Modeller membership.
Six functions, six animals with problems, one bonus.
One workbook per day, unlocked automatically. Do them live or catch up at the weekend. They're yours to keep either way.
Giles's favourite function, and the one that replaces VLOOKUP, HLOOKUP and a lot of INDEX/MATCH.
XLOOKUP's quieter sibling. Brilliant for positional logic.
Two functions, one challenge. Freya has lost things. Lots of things.
The function that makes most of your old helper columns redundant.
Deceptively simple. Surprisingly powerful when you combine it with the others.
The classic. Still the most flexible function in Excel.
We'll share a free Excel fundamentals course with you on day 7 as a 'thank you' for taking part, and asking for your feedback in the Function Challenge Series. If you fill in our feedback form, we'll offer you a free month of Full Stack Modeller membership. Cancel any time to avoid charges. Card details required.
Built for beginners. Open to everyone.
Beginners
If you know your way around a spreadsheet but you've never properly used dynamic arrays, you're exactly who we had in mind. The early levels assume nothing and walk you through the logic before asking you to do anything clever.
Intermediates
You'll breeze through the first few levels, but the later ones tend to catch out even confident users. You'll probably pick up a few tricks you didn't know were there.
Three steps, then you're in.
