Working with numerous sheets can be visually overwhelming, or perhaps you want to prevent others from viewing crucial sheets on your computer. Whatever the reason, you might want to hide and reveal sheets as needed.
You can execute the hide/unhide sheet operation using the methods below:
Note:
Excel files always need to display at least one sheet. Therefore, if an Excel file has only one sheet, you cannot hide that sheet.
You can hide multiple sheets at once by holding down the Ctrl key to select sheets. However, to display multiple sheets simultaneously, you need to install additional Add-ins.
Method 1: Hide/Unhide sheets using Excel 2007, 2010, 2013 toolbar.

Step 1: On the toolbar, choose Home -> Format -> Hide & Unhide -> Unhide Sheet.
Note: Unhide Sheet will only be highlighted when the Excel file has hidden sheets.

Method 2: Hide/Unhide sheet directly from the sheet tab.
