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 analyze data. Excel also enables users to easily create common graph types like bars, pie, columns, and lines to visualize and understand information in their spreadsheets. It offers formatting tools to enhance tables and buttons to insert tables, graphs, and mathematical functions for further analyzing and presenting data.
