INDEX function together with MATCH function Advanced Use

Did you ever fill that you need a formula that lookup with respect to column data together with column header name?



=INDEX(Data!$1:$1048576,MATCH(Output!$A:$A,Data!$A:$A,0),MATCH(Output!B$1,Data!$1:$1,0))


Formula Description:

MATCH(Output!$A:$A, Data!$A:$A, 0): This part of the formula uses the MATCH function to find the position of values in the "Cell Name" column of the "Output" sheet within the "Cell Name" column of the "Data" sheet. The 0 as the third argument signifies an exact match.

MATCH(Output!B$1, Data!$1:$1, 0): This part uses MATCH to find the position of the value in cell B1 of the "Output" sheet (presumably "Values-4") within the first row ("Values-1," "Values-2," etc.) of the "Data" sheet.

INDEX(Data!$1:$1048576, ..., ...): The INDEX function is then used to retrieve the value at the intersection of the row found by the first MATCH and the column found by the second MATCH. The range "Data!$1:$1048576" is a large range to cover a vast number of rows.

Purpose and Usage:
This formula is commonly used for dynamic data retrieval and mapping. It is especially useful when you want to pull specific data points from one sheet ("Data") to another sheet ("Output") based on matching criteria.

Example Use Case:
Consider a scenario where "Cell Name" in the "Data" sheet represents different devices, and the "Values-1," "Values-2," etc., represent different attributes of those devices. The formula could be used to dynamically fetch the value in "Values-4" for a specific device listed in the "Output" sheet.

Summary:
This formula allows for flexible and dynamic data extraction, facilitating the creation of summary sheets or reports where specific data points are needed based on matching criteria. It's a powerful tool for data analysis and reporting in Excel.
