I am currently achieving the process of extracting unique years from a range of dates with the use of helper columns shown here:
Is it possible to achieve the same using just a single formula?
Here are the three formulas I am currently using:
S column: =UNIQUE('Earnings Input'!A2:A)
T column: =YEAR(S1)
U column: =UNIQUE(T1:T)
Appreciate any help I can get!
As there is no link to your spreadsheet, this is untested, but you can try this:
=ArrayFormula(SORT(UNIQUE(YEAR(FILTER('Earnings Input'!A2:A,ISNUMBER('Earnings Input'!A2:A))))))
FILTER( ,ISNUMBER( ))
filters in only values that could reasonably be a date.
YEAR
gets the years for those entries.
UNIQUE
reduces to the unique listing
SORT
assures the results will be in ascending order.
