Spreadsheet software is a type of application that allows users to organize, analyze, and store data in a tabular format. It consists of rows and columns, where each intersection is called a cell. Users can input numbers, text, and formulas to perform calculations and create charts, making it a valuable tool for tasks like budgeting, data analysis, and project management. Popular examples of spreadsheet software include Microsoft Excel, Google Sheets, and Apple Numbers. These programs often come with features such as data sorting, filtering, and graphing capabilities, enabling users to visualize their data and make informed decisions based on their findings.
