Course Description

Arrays are a powerful Excel tool that can help you consolidate multiple steps, thereby simplifying and streamlining many Excel functions. This course was first developed for Excel 2007 and earlier versions where array formulas were necessary to perform operations such as summing data with multiple criteria, averaging data with multiple criteria, summing data ignoring errors and multiplying arrays. As Excel evolved, functions such as SUMIF, SUMIFS, AVERAGEIF, AVERAGEIFS, AGGREGATE, and SUMPRODUCT were developed to accomplish these tasks.

This straightforward and practical course walks you through each process with step-by-step instructions, explaining how arrays allow you to perform mathematical operations, find data, transpose numbers, match information, and quantify duplicates as well as quantifying and ignoring errors in data. The materials also detail using the Excel functions SUMPRODUCT and INDEX combined with MATCH and AGGREGATE. This course is certain to increase your efficiency and productivity in the workplace.
