Excel is spreadsheet software that allows users to create tables to organize and calculate data. It automatically calculates totals and values across cells and can print tables in neat layouts. Spreadsheets are made up of individual cells organized in tables where users can input information, perform calculations, and view relationships across data sets. Excel enables users to easily generate common graph types like bars, pie charts, columns and lines to visualize and analyze data trends. It offers formatting tools to enhance text and includes buttons to insert tables and choose different graph types. Functions can also be added to perform mathematical operations on the data.
