A Microsoft Excel workbook is really a container, a bit like a folder. Each Excel workbook contains one or more worksheets and it is the worksheet that is the actual container of your information. Worksheets are identified by a tab which carries the name of the sheet. Clicking a tab will activate that particular sheet.

In exactly the same way that Excel allows you to hide columns and rows, it is also possible to hide entire worksheets. Hiding a worksheet is particularly useful if your workbook contains a lot of sheets. Naturally, once hidden, worksheets can be made visible again by using the Unhide command. It is possible to hide either an single sheet or a group of sheets. However worksheets can only be unhidden a single sheet at a time.

To hide a single sheet, simply right-click on the sheet tab and choose Hide. The corresponding worksheet will then disappear. There is also a ribbon command which will do the same thing. First, highlight the sheet by clicking on its tab and then, in the Cell section of the Home Tab of Excel Ribbon, choose Format-Visibility-Hide and Unhide-Hide.

To hide more than one sheet at a time, simply highlight the sheets by clicking on the first, holding down the Control key on your keyboard and clicking on each of the others. Next, right-click on any of the highlighted sheet tabs and choose Hide.

To make a hidden worksheet visible again, you can right-click on any sheet tab and choose Unhide. The Unhide dialog then appears. Unfortunately, it isn't possible to select more than one sheet to unhide; if you try Control-click or Shift-click, you'll see that only one sheet can be highlighted. Highlight the name of the sheet that you want to make visible and click OK.

You can also use the ribbon command Format-Visibility-Hide and Unhide-UnHide Sheet. When the Unhide dialog appears, highlight the sheet you want to unhide and click OK. You'll notice that when sheets are unhidden they return to the positions that they originally occupied.
