Introduction
Excel converts raw data to useful data in rows and columns, allowing you to perform calculations, create charts, analyze data, and automate tasks with formulas and functions. The rows are represented using numbers, while the columns are represented by letters. Cells are where columns and rows intersect. Excel worksheets contain columns and rows, while the workbook has several sheets.
Uses of Excel in the real world
- To understand what is happening: A small shop owner can use Excel to track daily sales and could create a pivot table to show sales that are highest on weekends and lowest on Mondays, while a line chart reveals that phone accessory sales spike every December to help them understand which products sell when and plan stock accordingly.
- To spot problems: A teacher could use Excel to highlight all student grades below 50% in red, instantly spotting which students need extra help.
- To predict the future: A farmer can use Excel, with the last 3 years of rainfall and crop yield data, to predict next season's harvest, while a small business owner can use it to predict next month's sales based on the past 12 months, helping them decide how much inventory to order and when to hire temporary staff.

Excel has several functions. I have listed a few
ctrl+shift+$ is used to change the currency.

alt+H+O+Iis used to separate data.

Conclusion
Before learning Excel, all I saw was numbers and too much information. I thought it was just a data entry tool and that was it. Excel has taught me problem-solving skills, patience, keenness, and to slow down and listen to my data because behind every piece of data there is a decision to be made or a decision was made. Now I see Excel as a powerhouse for better decisions, and my perspective on data has definitely changed.

Good effort, Zenna. The article covers a relevant topic on how Excel is used in real-world data analysis; to improve it further, make sure the examples clearly show how Excel supports data cleaning, formulas, reporting, visualization, and decision-making.
Thank you.
