## Tapping into Power of Excel Functions

Excel has many built-in formulas that can be very basic or extremely complex called as ** worksheet functions**.

A formula is an expression that includes specific values and cell addresses which returns a particular result in the cell or a position specified in the syntax. These functions are useful because they are swift and straightforward for performing a spreadsheet task.

Below you can find the important functions of **seven** main categories:

## Text Functions

# CHAR
