in Excel, could we build on the =UNIQUE formula and have =UNIQUEIF and =UNIQUEIFS
with my current problem, I am looking at data spanning several years and I want to create a unique list of people for any given year/month at a time. by having a UNIQUEIF or IFS, i could link the IF part of the function to a cell with the desired year or month allowing my boss to get the answers he wants quickly and without having to ask me to do it for him.
The reason I am using =UNIQUE in the first place is so that I dont have to modify the sheet when new people appear or people disappear from the data being queries

You can filter the original array by whatever criteria you like and pass the filtered array to unique to extract the relevant data.

Hi @Andy M
Could you please give us a simple sample?
To make your formulas easier to manage and more flexible as data grows, I suggest you convert your data ranges to Tables:
Select your data range, press Ctrl + Q > Select "Tables" tab > Table.
This way, any new data added to the table will automatically be included in your formula without you needing to adjust the range each time.
In my sample, I named this table as " Table1" like the following image.
Then as Barry Schwarz suggested, you may combine Unique functions with Filter functions.
If you want to filter by a specific month and year, such as November 2024, you can try the formula: =UNIQUE(FILTER(Table1[Name], (YEAR(Table1[Date]) = 2024) * (MONTH(Table1[Date]) = 11))).
