Help on a UNIQUE formula

Occasional Visitor


I have the following list of year:

2022 2023 2023 2025 2025 2026 2027 2028 

from A1:K1

I wish to find the single values and put the following formula in B1=SINGLE(A1:K1)

but got the sames values.

What I'm doing wrong ?

I believe you want the unique function:

UNIQUE works down the array to generate a distinct set of rows.  To do the reverse and work from left to right across an array (here just a single row) you need to add a further parameter

= UNIQUE(year,1)

where 'year' is a defined name that refers to A1:K1.

Hi @Peter Bartholomew 

Thank you very much


I am not getting the option to use unique function in professional 2019. Please help


That's for Excel 365, Excel for web or Excel 2021

Dear Sergei,


Please help me out with any alternative of unique function that can give me unique dates automatically from a list of entries.


I am not the best person to ask because this time I deliberately erased older versions of Excel and decided that I had no interest in maintaining compatibility with those older versions.  However, I remember tricks such as using MATCH to identify the first occurrence of the value (in your case, a date) and return the relative row number of such matches.  SMALL will then filter the row numbers which are ultimately used to lookup the values/dates.


I can't help but feel that

= UNIQUE(dates)

is clearer in its intent!
