1. One Click to Select All You might know how to select all by using the Ctrl + A shortcut, but few know that with only one click of the corner button, as shown in the screenshot below, all data will be selected in seconds.

10. Generate a Unique Value in a Column You are aware of the key function of Filter, but few people use the Advanced Filter, which will be repeatedly applied when you need to filter a unique value from data in a column. Click to choose the column and go to Data->Advanced. A pop-up window will show up. As the screenshot shows, click Copy to another location, which should be in accord with the second red rectangular area. Then specify the target location by typing the value or clicking the area-choosing button. In this example, the unique age can be generated from Column C and show in Column E. Don’t forget to choose Unique records only, then click OK. The unique value showing in column E can be the contrast of the original data in C, that’s the reason why it is recommended to copy to another location.
