Excel SINGLE Function

Excel SINGLE function
Summary 

The Excel SINGLE function returns a single value using implicit intersection. The SINGLE function is provided for backwards compatibility with implicit intersection formulas in earlier versions of Excel.

The SINGLE function was originally introduced with Dynamic Arrays, but later deprecated in favor of the @ character.
Purpose 
Get single value with implicit intersection
Return value 
Cell or value at implied intersection
Syntax 
=SINGLE (value)
Arguments 
  • value - Value to evaluate using implicit intersection.
Usage notes 

The Excel SINGLE function returns a single value using implicit intersection. The SINGLE function is primarily for backwards compatibility with implicit intersection formulas in earlier versions of Excel.

When the supplied argument is a range, SINGLE will return the cell at the intersection of the row or column of the formula cell. Where there is no intersection, or more than one intersection, SINGLE returns a #VALUE! error.

In the example shown, the following formula in D6 "spills" and returns all values in the range B4:B8:

=B4:B8

When the single function is wrapped around the same range, SINGLE returns 3, which corresponds to cell B6, which intersects with the formula in cell D6:

=SINGLE(B4:B8)
The SINGLE function was originally introduced with Dynamic Arrays, but later deprecated in favor of the @ character.
