The formulas ChatGPT spit out aren't working. Its suggesting =counta(unique(filter(a:a,b:b=e3))) but that just returns "1"

I have a data set like below:



I need to find the number of unique dates that have apple in column B. Answer would be 2. The dataset could be upwards of 50k rows. TIA

OK, I tried what you have and it worked for me.

ETA: Could it be you have a space in one of the descriptions or something marginally different between what is in E3 and what is in the columns you are looking at?

Same

Different methodology, if you copy the table to a new sheet. Convert to an excel table. Click remove duplicates. Summarize with a pivot table, filtered on "apple".
