Here is my experience in Excel. I have worked in a restaurant before, and I know that their cashier system is a form of excel. The systems could keep track on how the restaurant earns daily and even could keep track if any things have been damage or lost daily. The system could also keep track on what food people had ordered.This system could be great if we could set up in our home and keep track on our grocery.
As far as I know Excel is a very useful tools in the real life. Professor use excel to take attendance and forming presentations in class. Excel is easy to use and keep tack things daily.
Accountant and Entrepreneur use excel to keep track on their sales and budget. Excel could help them to analyze important data and preset formula to work out complicated balance sheet.
Students use Excel to do their homework and also analyze data on Excel.
Excel is used in the workplace to receive great amounts of data and faster calculations.
