Hi, my name is Jacek and I love spreadsheets! Whether you’re hoping to improve your spreadsheet skills and master spreadsheet programs — such as Microsoft Excel and Google Sheets — or you’re looking to take control of your data by developing your data analytics and financial modelling skills, I have just the courses for you.
Using my experience from over 10 years in Commercial Finance and Data Analysis, and my passion for data, I’ve created Excel and data analytics online courses for people of all abilities.

All of my courses are one-to-one. This means the lessons are tailored to your specific needs, taking into account your previous experience, with the pace of the course adjusted to suit your pace of learning.
Benefit from Hands-On Learning
To help you build your confidence in working with data, I include hands-on learning activities in my courses. You can apply lessons learned to spreadsheets or financial models with me on-hand to offer assistance and guidance.
Learn to Love Data
For many people, working with spreadsheets and making sense of data can feel like a chore. But believe it or not, I’m passionate about data and it’s potential. So my goal is not just to help you learn how to create spreadsheets and make the most of data — I aim to help you enjoy organising, analysing and presenting data.
