What is a workbook in Excel?

A workbook in Excel refers to an Excel file that contains one or more worksheets. This structure allows users to organize related data within a single file, making it easier to manage and analyze information. Each worksheet can have its own set of rows and columns, allowing for separate datasets while still being part of the same workbook. This is particularly useful for maintaining related tables, figures, or data for different scenarios (such as different months, departments, or projects) in one cohesive file. Excel users often switch between worksheets using tabs located at the bottom of the workbook to access different sets of data, making the workbook a fundamental component of Excel's functionality in data organization and management.

In contrast, a cell is a single data point within a worksheet, a specific formula is a way to perform calculations on data contained within cells, and a visual graph of data is a representation of data from the worksheets but doesn't constitute a workbook itself. Understanding the distinction between these elements is crucial for efficiently navigating and utilizing Excel for various tasks.
