=AREAS(reference)
=AREAS(A1:C1)
This function allows you to count the number of references in a range, and returns 1 because there is only one reference.
=AREAS((A1:C1,A2:C2))
You can also use this function to count multiple references in a range. For example, This formula returns 2 because there are two references.
=AREAS((F17:F19,J16:J18,I8))
This function also works with a range of non-contiguous cells. For example, This formula returns 3 because there are three references.
The AREAS function counts the number of areas in a reference. An area is a single cell or a range of contiguous cells. When inputting multiple references, extra parentheses must be used to prevent Sourcetable from interpreting the comma as a field separator.
