workbook

In educational settings, a workbook is distinct from a textbook; while a textbook provides the primary instructional content and theory, the workbook is a practical tool for application, often featuring fill-in-the-blank sections or problem sets. It is designed to be written in, making it a consumable resource rather than a reference volume.

In a computing context, specifically within spreadsheet software, the workbook serves as the top-level container. It is important to distinguish the workbook (the entire file) from the worksheet (an individual tab or page within that file). A single workbook can house multiple worksheets, allowing for the organization of related data sets within one document.
