## Summarize Data with Conditional Functions in Excel

Excel users are often faced with spreadsheets that summarize sales data for multiple areas, such as states within the U.S. or individual countries.

Functions such as SUM or AVERAGE let you summarize your data as a whole—but it can be difficult to find the totals, averages, or counts for subsets of that data. For example, suppose you want to find the total of all sales to Canada. To do that using a standard SUM formula, you would have to identify cells that contain values for all sales to Canada and then create a formula for just those cells.

Fortunately, there’s a set of conditional functions in Excel that let you specify which values should be included in a sum, average, or count calculation. Those functions are: SUMIF, SUMIFS, AVERAGEIF, AVERAGEIFS, COUNTIF, and COUNTIFS.

## Excel’s VLOOKUP and HLOOKUP functions explained

When looking up information in Microsoft Excel, you’ll regularly need to compare data against a table—and tables can be found in a variety of locations and formats. For example, in the image above you may need to find the appropriate tax rate in the table on the right for a given employee’s salary listed in the table on the left.

On the Formulas tab in the Excel ribbon, you’ll see a categories function called Look up and Reference. The two key functions for this type of task are VLOOKUP (V meaning vertical) and its companion function HLOOKUP (H meaning horizontal).

Why two functions instead of one? As shown in the image below, data tables can be found in horizontal and vertical orientations—so with two dedicated functions, you’re covered either way.
