In Excel 2007, it's possible to enter the same data into several worksheets without retyping or copying and pasting the text into each one. As an example, let's say you want to put the same title text into different worksheets. One way to do this is to type the text in one worksheet, and then copy and paste the text into the other worksheets. If you have several worksheets, this can be very tedious.
An easier way to do this is to use the CTRL key to group worksheets. When worksheets are grouped, whatever you do to one worksheet affects all other worksheets.
Start Excel. A new, blank workbook appears.
Press and hold the CTRL key, and then click Sheet1, Sheet2, and Sheet3.
This temporarily groups the worksheets. In the title bar, you should see the name of the workbook followed by the word [Group].
Click in cell A1 in Sheet1, and then type:
This data will appear in each sheet.
Click Sheet2 and notice that the text you just typed in Sheet1 also appears in cell A1 of Sheet2. The text also appears in Sheet3.
Tip: When you click another worksheet, Excel automatically ungroups the worksheets for you.
