This article, I will talk about how to deal with this job in Excel.

• It may be common for us to count unique values in only one column, but, in this article, I will talk about how to count unique values based on another column. For example, I have the following two columns data, now, I need count the unique names in column B based on the content of column A to get the following result.

• Count Unique Values In Pivot Table
• By default, when we create a pivot table based on a range of data which contains some duplicate values, all the records will be counted as well, but, sometimes, we just want to count the unique values based on one column to get the right screenshot result.

NONE of your formulas work, following your steps I get either #VALUE! or a formula that doesn't calculate and the text of it just sits there in the formula bar. And by NONE I mean all the ones with formula text I could copy and paste. Are your tutorials only for users with Excel 365 or something? Because for me on 3 different PCs with Windows 10 and Office Pro Plus 2016 the formula =COUNTIF(A2:A12,A2:A2) returns 0, making all the more complex formulas fail with #VALUE! Also the Terms and Conditions checkbox for this comment was covered by the useless "share" strip on the left margin. I hate bad web design presenting useless tutorials.

Found out the problem with the formulas to count unique/distinct values in a range. Short answer: Excel STINKS. Long answer: The formulas work for up to about 5000 cells of data and after that performance degrades with more cells of data. With 55,624 cells of data like I have the formula completely fails and returns #VALUE! or 0 after a few minutes. And a few times while experimenting with capacity Excel crashed and mangled the spreadsheet file. Personally I think formulas that can fail spectacularly and damage a file should NOT be posted for an unsuspecting world as "solutions" to try but maybe other people are more tolerant of file destruction than I am.
