Microsoft Excel displays data in Worksheets, also called spreadsheets, or as a group of worksheets known as a Workbook.
To perform one function that will work on all the sheets.
When worksheets are grouped in Microsoft Excel, the Title Bar displays the name of the active workbook followed by the phrase "Group" or "Group of [number] Sheets." This indicates that multiple worksheets are currently selected and any changes made will affect all grouped sheets simultaneously. The title helps users recognize that they are working in a grouped state to prevent unintended edits to individual sheets.
The word Group appears in the title bar. It appears in square brackets, so as not to be confused with the workbook's name. So if the workbook was called Sales, in the title bar you would see: Sales [Group] - Excel
If worksheets are in one line, then hold SHIFT and click on one end and then the other end, if not in order, then hold CTRL and click on the worksheets you want to group.
