Inserting a tab in Microsoft Excel allows users to create a new worksheet within an existing workbook. It enables efficient organization and management of data by separating different sets of information into distinct tabs.
Tabs play a crucial role in Excel by offering several advantages. They provide quick and easy access to specific worksheets, facilitating seamless navigation between different sections of a workbook. Additionally, tabs help maintain data integrity by isolating changes made to individual worksheets, preventing accidental modifications to other parts of the workbook.
