如何基於Excel中的另一列計算唯一值？

按條件唯一的文檔數1

僅在一個列中對唯一值進行計數可能很常見，但是在本文中，我將討論如何根據另一列來對唯一值進行計數。 例如，我有以下兩列數據，現在，我需要根據A列的內容計算B列中的唯一名稱，以獲得以下結果：

為解決此問題，以下公式可以為您提供幫助，請執行以下操作：

1。 輸入以下公式： =SUMPRODUCT((($A$2:$A$18=D2))/COUNTIFS($A$2:$A$18,$A$2:$A$18&"",$B$2:$B$18,$B$2:$B$18&"")) 放入要放入結果的空白單元格中 E2， 例如。 然後按 Ctrl + Shift + Enter 鍵在一起以獲得正確的結果，請參見屏幕截圖：

備註：在以上公式中： A2：A18 是您根據其計算唯一值的列數據， B2：B18 是您要計算唯一值的列， D2 包含您認為唯一的標準。

2。 然後向下拖動填充手柄以獲取相應條件的唯一值。 看截圖：

Hello, DM,
In fact, you can enlarg the cell references as you need. For example:
=SUMPRODUCT((($A$2:$A$10000=D2))/COUNTIFS($A$2:$A$10000,$A$2:$A$10000&"",$B$2:$B$10000,$B$2:$B$10000&""))
Please remeber to press Ctrl + Shift + Enter keys together.
Please have a try, hope it can help you!

Hello, MB
To count the unqiue values with criteria and skip the blank cell, you should apply the below array formula:
=SUM(--(FREQUENCY(IF($B$2:$B$15<>"",IF($A$2:$A$15=D2,MATCH($B$2:$B$15,$B$2:$B$15,0))),ROW($B$2:$B$15)-ROW(B2)+1)>0))


After pasting the fromula, please press Ctrl + Shift + Enter keys together.

Thank you very much for this but how does it work with a large data set. I realised it returns #N/A when the data is beyond row 78

I would need to do something similar but with dates: on a sheet in which the dates are indicated in the first column, many repeated, I would like to know how many different dates there are that meet a certain condition that appears in another column. I am applying that formula but it gives me an error. Could you help me? Thanks.

Does anyone know what the ampersand-quotes (" &"" ") in the Criteria 1 and 2 portion of the COUNTIFS formula is doing? This formula worked for me I was just hoping to understand it better.

Hello, EB, To count the unique values based on two columns, please apply the below formula, after entering the formula, please press Ctrl + Shift + Enter keys together to get the correct result.=SUM(IFERROR(($A$2:$A$15=E2)*($B$2:$B$15=F2)/COUNTIFS($C$2:$C$15,$C$2:$C$15,$A$2:$A$15,E2,$B$2:$B$15,F2),0))
Please try, hope it can help you!

This works great, but what if you need to add a 3rd column of criteria and what if some cells have blanks and you don't want to count the blanks?
