Excel charts allow spreadsheet administrators to create visualizations of data sets. By highlighting a set of data within an Excel spreadsheet and feeding it into the charting tool, users can create various types of charts in which the data is displayed in a graphical way.

A chart can create a clearer picture of a set of data values than a table with rows of numbers in it, allowing managers to incorporate this understanding into analysis and future planning. Benefits of charts and graphs also come into play in presentations, where they can be used to quickly illustrate trends in data for others to see.
It's often easier to spot trends and patterns in graphs and charts than by simply looking through a long table of data, especially for big datasets, so one of the common uses of chart tools is in simply coming to grips with what a new dataset actually means.
