Introduction
In today’s digital world, data is everywhere. Businesses, schools, hospitals and organizations collect large amounts of information every day. One of the most commonly used tools for organizing and analyzing this data is Microsoft Excel.
Before starting my data analytics journey, I viewed Excel as a simple spreadsheet application mainly used for typing tables and performing calculations. However, after learning more about it during my training at LuxDevHQ, I now understand how powerful and important it is in real-world data analysis.
What is excel
Microsoft Excel is a spreadsheet software developed by Microsoft that helps users:
- Organize data
- Perform calculations
- Analyze information

My Personal Reflection
At first, I thought Excel was something simple and easy. However, after attending classes and practicing different features and formulas, I now realize that Excel is a powerful analytical tool used in real-world industries.
Even with the few classes I have attended so far, I already feel more confident working with data. I can now:
- Find insights from datasets
- Calculate totals and averages
- Clean messy data
