Watch this video to find out the method used by Bill Szysz to get multiple lookup results in Excel. This example builds on the example shown in the previous videos which has a matrix of apps which belong to different divisions. The apps are the values inside the matrix and the divisions are the headers. The aim is to find the header value based on the matrix value. Since the data in this example is not unique and an app can belong to more than one division, the aim is to come up with a formula that finds all the divisions one app could belong to.
Excel's TEXTJOIN function is a great solution to this problem. On top, when combined with the Find & Isnumber function, it can help us avoid duplicate results. Watch this video as I take you through Bill's formula solution.
