<human>:  I'm having difficulty understanding how to use Excel. Can you explain the basics?
<bot>: Sure! Excel is essentially a program that helps you organize vast amounts of data. It can keep track of all your expenses, allowing you to quickly formulate budgets and project outcomes. It can also be used to chart anything from numbers to trends in a visual way. Fundamentally, Excel relies on its ability to store, calculate and analyze data in small cells. Each cell contains information, including numbers, text, or formulae which can be used both individually and in combination with other cells, to gain an overview of complex data.
