When the formula is copied down, it returns an index for each column listed in column H. Getting an index like this is useful when you want to refer to table columns by index in other formulas, like VLOOKUP, INDEX and MATCH, etc.
How this formula works
This is a standard MATCH formula where the lookup values come from column H, the array is the headers in Table1, and match type is zero, to force an exact match.
The only trick to the formula is the use of a structured reference to return a range for the table headers to the MATCH function:
The nice thing about this reference is that it will automatically adjust to any changes in the table. Even when columns are added or removed, the reference will continue to return the correct range.
To do a two-way lookup in an Excel Table , you can use the MATCH function with a structured reference and VLOOKUP. In the example shown, the formula in I5 (copied down) is: = VLOOKUP ( $I$4 , Table1 , MATCH ( H5 , Table1 [ #Headers ], 0 ), 0 ) How...
MATCH is an Excel function used to locate the position of a lookup value in a row, column, or table. MATCH supports approximate and exact matching, and wildcards (* ?) for partial matches. Often, the INDEX...
This video shows how to setup VLOOKUP with a table, and how to use the MATCH function inside VLOOKUP to generate a dynamic column index. This makes it easy to refer to columns by name inside VLOOKUP, instead of hardcoding the column number. As a...
