What is a collection of one or more spreadsheets in Excel called?

In Excel, a collection of one or more spreadsheets is termed a workbook. A workbook serves as the primary file format for saving multiple worksheets, which are individual pages within the file that can contain data, charts, and formulas.

Workbooks are essential for organizing related data, allowing users to work on multiple sheets simultaneously while managing them under a single file. Each worksheet within a workbook can be accessed through tabs at the bottom of the Excel interface, making it easy to navigate between them. Understanding this organization is fundamental for effective data management in Excel, as users often need to relate data across different sheets.

In contrast, a worksheet refers to a single spreadsheet within a workbook. The formula bar is a feature used for entering or editing data and formulas in the active cell, while the name box displays the name of the active cell or range. These features are all crucial for functionality within Excel but do not represent the overarching structure that a workbook provides.
