如何使用Excel查找某个变量的最后一个数字（连续）

Question

The implementation include a lot of data. For simple example in this Image I should be able to find the last number in the row either "500" for "Amy", "700" for "Sam", etc.

Kindly need all your help to figure this out. Thanks in advance..

Answer 1

The following formula entered as array formula (by using Ctrl+Shift+Enter) could be used:

=INDEX($C$2:$C$9,MAX(($A$2:$A$9=E2)*(ROW($A$2:$A$9)-ROW($A$2)+1)))

For F2, where the last amount for Amy is being calculated:

($A$2:$A$9=E2) returns an array of True and False for those that match Amy

(ROW($A$2:$A$9)-ROW($A$2)+1) gives an array for the rows in the dataset. $A$2:$A$9 is the range for the names, $A$2 is the first name in the dataset.

The two above multipled together gives the row numbers in which Amy was found.

MAX() then gives the highest row number, which is used by INDEX to retrieve the Amount matching this row number.
