A worksheet is a table of data that is organized into rows and columns. It is commonly used in spreadsheet software to input, calculate, and analyze data. Worksheets allow users to arrange and manipulate data in a structured format, making it easier to understand and work with large amounts of information. They provide a visual representation of data, with each cell in the table containing a specific value or formula. Users can perform various operations on the data, such as sorting, filtering, and performing calculations, to derive meaningful insights and make informed decisions.
