根据 Excel 中的特定值查找行名

Question

I have a matrix dataset with values in Excel, where row and column names are identical. I have put all matrix values in a single column, but would now like a formula that returns the matching row name and/ or column name for that value. I have tried VLOOKUP and versions of INDEX and MATCH, but can't get it to work.

Here's an illustration of the data:

Answer 1

You are not looking for a rowname or a columnname, you are looking for the content of the first row or column:

Imagine you want to know the "columnname" of cell "C4", then you just ask for Cell(3,1) (3 meaning "C").
Imagine you want to know the "rowname" of cell "C4", then you just ask for Cell(1,4) .

Answer 2

Setup:

Source table range A1:D4

Values populated in column H for checking.

Formula in cell F2:

=IFERROR(INDEX($A$1:$A$4,MIN(IF($B$2:$D$4=H2,ROW($B$2:$D$4),10^10))),"")

Formula in cell G2:

=IFERROR(INDEX($A$1:$D$1,1,MIN(IF($B$2:$D$4=H2,COLUMN($B$2:$D$4),10^10))),"")

Depending on your version, you may have to use CTRL+SHIFT+ENTER to implement these formulas. Output will be like below.
