如何在Excel中为重复或唯一值分配序列号？

如果您有一个包含一些重复项的值列表，我们是否可以为重复项或唯一值分配顺序号？ 这意味着为重复值或唯一值给出一个顺序，如下图所示。 本文中，我将讨论一些简单的公式来帮助您解决Excel中的这一任务。

使用公式为序列号分配重复值

使用公式将序列号分配给唯一值

要订购重复值，请应用以下公式：

输入以下公式： = COUNTIF（$ A $ 2：A2，A2） 插入数据旁边的空白单元格，然后将填充手柄向下拖动到要应用此公式的单元格，并且已基于重复值分配了单元格值，请参见屏幕截图：

doc分配重复项唯一2

箭头蓝色右气泡 使用公式将序列号分配给唯一值

要将序列号分配给唯一值，以下公式可能会有所帮助：

输入以下公式： =IF(COUNTIF(A$2:A2,A2)=1,MAX(B$1:B1)+1,VLOOKUP(A2,A$1:B1,2,0)) 放入数据旁边的空白单元格中，然后将填充手柄向下拖动到要应用此公式的单元格中，并且唯一值的排序如下所示：

doc分配重复项唯一3

笔记：

1.在上式中 A2 是包含您要分配的值的单元格， B1 是您的公式所在的上述单元格。

2.这些公式也可以应用于排序列表中的值，并且您将根据需要获得以下结果：

Thanks for the formula, my only problem is that I want the generated 'unique identifiers' to be locked/linked to the 'values' but whenever I sort the table, the identifiers always remain in the same spot. Is there a way so that they stay linked to one another?

For example, I am using this code to assign serial numbers to customers, these need to be permanently assigned to one another as they do not change. However, when I sort the table by date, customers or anything at all that re-arranges the data. The serial numbers all get mixed up.

Is it possible to assign such serial numbers within the same cell? I have a sheet that does this using a macro, but I cannot access the macro (password protected) to see how they did it.
Disclaimer: I have permission to access the macros, but it is an old sheet and the passwords are lost.
