Name: The Hidden Keys to Unlocking Dynamic Array Calculations in Excel | Mark Proctor
Start: 2025-08-07T17:00:00.000Z
Location: Canada Water Library

In this meetup, we welcome Agnieszka Nyka to present on how creating and solving puzzles for fun in Excel can improve our skills for when it really matters.

**What to Expect**
What do a Rubik’s cube, a Galton board, and a spreadsheet have in common? For this Excel-obsessed accountant, they’ve each sparked some of her most unexpected breakthroughs in problem-solving.

In this light-hearted (but sneakily deep) session, Agnieszka Nyka shares her journey of recreating traditional puzzles in Excel—not to show off advanced formulas, but to explore how creativity, logic, and structured thinking can transform how we think about spreadsheets – at work and beyond.

This isn’t a technical deep dive, but rather an exploration of creative logic, real-world problem- solving and seeing Excel as a thinking tool—not just a reporting one. Expect quirky builds, nerdy humour, and a reminder that what looks complex is often powered by simple, structured ideas. And sometimes the fastest way to grow is to build something just for the fun of it.

This is an **in-person only** event.

The event will be held in
Meeting room 3,
Canada Water Library,
21 Surrey Quays Rd, London SE16 7AR.
