How to get max date from one column and match with other column in Excel?

问题

I have excel sheet data like below

CustomerNo LoginDate
101        25/05/2012
101        10/05/2012
101        20/05/2012
101        10/04/2012
102        21/05/2012
102        12/04/2012
103        20/05/2012
104        08/04/2012

I want to get last login date match with customer number and result like below.

101   25/05/2012
102   21/05/2012
103   20/05/2012
104   08/04/2012

You may use the DMAX function to do this.

First, I am putting CustomerNo in A1 and 08/04/2012 in B9. Then I am naming that range "theTable".

Second, I add A11 and B11 my Criteria, "CustomerNo" and "LoginDate".

Then in A12, I place 101.

Finally I am ready for my DMAX function.

In B12, I place =DMAX(theTable,"LoginDate", A11:A12)

Excel will place 25/05/2012 in B12.

You could try a pivot table. This has the nice ability to get the max for all customer numbers at once and can be updated quickly if any of the data changes.

Select your nicely-formatted table
Insert | Pivot Table
Drag CustomerNo to Row Labels
Drag LoginDate to Values
Change the Value Field Settings (e.g., by right clicking any value in the pivot table) to Summarize by Max

There are two ways:

With array function (Press Ctrl + Shift + Enter):

=MAX(IF($A$2:$A$9=C2,$B$2:$B$9))

Regular formula:

=MAX(INDEX(($A$2:$A$9=C2)*($B$2:$B$9),,1))

I personally like the 2nd way better since array function will slow down PC performance for huge data. Anyway, hope this helps.
