Excel Changed in 2020.
Most Professionals Missed It.
Microsoft rebuilt how Excel works and added functions like FILTER, SORT, UNIQUE, XLOOKUP, and SEQUENCE. If you have Microsoft 365, you already have them.
But here’s the thing: the rollout happened during the pandemic. Everyone was working from home and dealing with everyday chaos. So most people who’d been using Excel for years just… kept doing things the old way.
Five years later, they’re still copying formulas down hundreds of rows, manually sorting data, and spending hours on reports that could take minutes.
If you’re still using VLOOKUP for everything, manually removing duplicates, or copying and pasting to sort data, you’re working at least 10 times harder than you need to.
These functions are standard now. This is how Excel works today. Once you see what they can do, you’ll wish you’d learned them sooner.
This course will teach you exactly how to use them with real-world examples, not just theory.
When Microsoft first rolled out these functions, they called them “Dynamic Arrays” functions. But this term confused many people, because it made it sound like they were reserved for Excel wizards – not for average Excel users.
Since then, Microsoft has toned down the terminology. You might still hear “Dynamic Arrays” used in videos and tutorials, but really these are just some new functions to help you get your work done faster and easier in Excel.
In fact, they are easier to learn than the IF or VLOOKUP functions.

I highly recommend this well-organized course for anyone whose work/projects involve data analysis. The knowledge I’ve gained on the new dynamic array functions will raise the level of my analysis while making my work easier at the same time. The new functions are well explained with business examples, and the course notes will be a great reference!

I’m Leila.
Nice to meet you.
Each month, I hop on a special video call with the Microsoft team. This is one of the perks of being a Microsoft MVP. They fill us in on all the latest features coming down the pipeline.
I love these calls and leave them as excited as a kid on their birthday.
But I also ask myself this question: “How are everyday people going to learn this?”
For years, I worked as a project manager at a multinational paper & packaging company. Excel was my #1 tool. Without it, I’d be lost. And let me tell you – I sure worked some magic at that company. Some of the Excel automations I had to create… wow, talk about beasts.
But you know the saying: What doesn’t kill you makes you stronger. And safe to say I can now use Excel with the best of them.


This course has enabled me to finish jobs in 5–10% of the time due to my ability to process Excel so far. It has also given me the confidence to better get around Excel.
