Excel SORTBY Function

Summary
The Excel SORTBY function sorts the contents of a range or array based on the values from another range or array. The range or array used to sort does not need to appear in results.
Purpose
Sorts range or array by column
Return value
Sorted array
Syntax
=SORTBY (array, by_array, [sort_order], [array/order], ...)
Arguments
- array - Range or array to sort.
- by_array - Range or array to sort by.
- sort_order - [optional] Sort order. 1 = ascending (default), -1 = descending.
- array/order - [optional] Additional array and sort order pairs.
Usage notes
The Excel SORTBY function sorts the contents of a range or array based on the values from another range or array. The range or array used to sort does not need to appear in results. In the example shown, the formula in E5 is:
=SORTBY(B5:B14,C5:C14,-1) // sort by grades descending
The output in E5:E14 is the list of names sorted by scores in descending order. To sort by grades in ascending order use:
=SORTBY(B5:B14,C5:C14,1) // sort by grades ascending
Note: The SORTBY function is a new "Dynamic Array Function" in Excel. It is a beta feature available only through the Office Insiders program. Dynamic Array functions are expected to be released in 2019 to Office 365 subscribers.
