Excel's ability to create automatic subtotals is a handy feature that can save you a great deal of time.

In addition to manual data filtering, Excel enables fully automated filtering based on data from the specified range of cells. Before using the advanced filtering feature, you must set up a criteria range. A criteria range is a designated range on a worksheet that conforms to specific requirements.

When you first start most of the Microsoft 365 applications, you'll see a new feature called the Start screen.

You can easily count the number of unique values of the range using a simple formula.

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.

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.

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.

The easiest way to enter a function into a formula is to use the Excel program's Insert Function dialog box.

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.

If you prefer to avoid the empty workbook to be created when Excel starts up, you can do so by editing the command line that is used to start Excel.
