20 Shade Alternate Rows: This example shows you how to use conditional formatting to shade alternate rows.

21 Quick Analysis: Use the Quick Analysis tool in Excel to quickly analyze your data. Quickly calculate totals, quickly insert tables, quickly apply conditional formatting and more.

22 Sparklines: Sparklines in Excel are graphs that fit in one cell. Sparklines are great for displaying trends. Excel offers three sparkline types: Line, Column and Win/Loss.

23 Slicers: Use slicers in Excel to quickly and easily filter pivot tables. Connect multiple slicers to multiple pivot tables to create awesome reports.

24 Trendline: This example teaches you how to add a trendline to a chart in Excel.

25 Pivot Chart: A pivot chart is the visual representation of a pivot table in Excel. Pivot charts and pivot tables are connected with each other.

26 Subtotal: Use the SUBTOTAL function in Excel instead of SUM, COUNT, MAX, etc. to ignore rows hidden by a filter or to ignore manually hidden rows.

27 Combination Chart: A combination chart is a chart that combines two or more chart types in a single chart.

28 Randomize List: This article teaches you how to randomize (shuffle) a list in Excel.

29 Unique Values: To find unique values in Excel, use the Advanced Filter. You can extract unique values or filter for unique values.

30 Icon Sets: Icon Sets in Excel make it very easy to visualize values in a range of cells. Each icon represents a range of values.
