Unique items in the list
To get unique items from a range, you can use the Advanced Filter to extract the unique values from a column of data and paste them to a new location.
How to select all the embedded charts on the worksheet
If you need to select all objects embedded into the worksheet, e.g., select all charts to adjust their size, press Ctrl+G and click the Special button or use Ctrl to select objects individually.
Adding and removing page breaks
On the printing spreadsheet, you might not be satisfied with the current pagination, so you might need to insert or remove manual a page break.
Viewing a worksheet in multiple windows
Sometimes, you may want to view two different parts of a worksheet simultaneously - perhaps to make it easier to reference a distant cell in a formula. Or you may want to examine more than one sheet in the same workbook simultaneously.
How to avoid misleading numbers
Applying a number format to a cell doesn't change the value, but only how the value appears in the worksheet. Formatting can play a joke with you, e.g., the sum of values seems incorrect because Excel displays a limited number of decimal places, and their sum is not equal to the real sum.
Changing moving direction of the cell pointer after entering data
Excel automatically moves the cell pointer to the next cell down when you press the Enter key after entering data into a cell, but you can change this behavior to move it up, down, left, right, and even stay on.
How to insert functions into formulas
The easiest way to enter a function into a formula is to use the Excel program's Insert Function dialog box.
Using a custom sort order
In some cases, you may want to sort your data in non-standard ways. For example, if your data consists of month names, you usually want it to appear in month order rather than alphabetically.
Adding a header and footer to the worksheet
Headers and footers are widely used in the Microsoft Word document, but you should know that Excel has headers and footers too.
Adding a background image to the spreadsheet
You can make your Excel spreadsheets more appealing by choosing a graphics file to serve as a background for a spreadsheet similar to the wallpaper that you may display on your Windows desktop.
