获取范围内最后一个非空单元格的列号（如果值不是唯一的）

Question

I have the following Excel-Spreadsheet:

     A  B  C    D       E       F       G      H     I      J     
1
2
3
4              200     150     80     300                   4
5              200     150     80     150                   2
6
7

In Range J4:J5 I have the following formulas:

J4 = MATCH(LOOKUP(2,1/(D4:I4<>0),D4:I4),D4:I4,0)
J5 = MATCH(LOOKUP(2,1/(D4:I4<>0),D4:I4),D4:I4,0)

With this formula I want to identify the last non-empty cell within the range and get the the column number of it back. All this works perfectly in Cell J4 .

However, in Cell J5 I get back number 2 instead of number 4 . As far as I can see the reason for this is that in Range D5:I5 the values are not unique (150 appears two times).

What do I need to change in my formula to always get the column number of the last non-empty cell no matter if the values are unique or not?

The answer from this question does not help because my range is not starting in Column A .
The range can be anywhere on the sheet.

Answer 1

Alternatively, you can adjust your existing LOOKUP function as follows:

=LOOKUP(2,1/(D4:I4<>0),COLUMN(D4:I4)-MIN(COLUMN(D4:I4))+1)

Answer 2

You only need MATCH:

=MATCH(1E+99,D4:I4)

if you are looking for text then:

=MATCH("zzz",D4:I4)

Or either:

=MAX(IFERROR(MATCH(1E+99,D4:I4),0),IFERROR(MATCH("zzz",D4:I4),0))

---

The issue is that the LOOKUP returns the actual value, in the case of the error it returns 150 to the MATCH:

MATCH(150,D4:I4,0)

Which will return the first match location.
