One in eight people rely on Excel for their work
Mastering Excel is a crucial skill for professionals because it’s one of the most widely used tools in the world. With over 1.2 billion users, about one in eight people rely on Excel.
Office workers spend nearly 40% of their time using it, making it a key part of daily work across industries.
Even advanced companies like Amazon, using intensively Artificial Intelligence and Machine Learning, expect their employees to be Excel experts.
Yet, most people still struggle with Excel.
Many don’t know how to use features like formulas, pivot tables, Macros, or Power Query. This leads to wasted time on repetitive tasks instead of focusing on data analysis and problem-solving.
Our latest survey demonstrates that 95% of the respondants didn’t fully understand Excel’s key functions,. This may be the case for you too if you:
- Don’t master the various features (Simple & complex formulas, pivot table, Macros, Power Query…)
- Waste time and energy from repetitive tasks
- Spend too much time creating Excel tables, and not enough time analyzing the data in those tables
- Have no results, resulting in daily stress.
Without strong Excel skills, professionals often feel stressed and unproductive. Learning Excel doesn’t just save time—it helps people work smarter, achieve better results, and reduce everyday frustration.
