How to use the INDEX function to find data in a table in Excel

Summary

This article describes how to use the INDEX function to find data in a table at the intersection of a specific row and column in Microsoft Excel.

There are two forms of the INDEX function, Array and Reference. The primary differences between the two forms are as follows:
  • The Array form can return more than one value at a time. The Reference form returns the reference of the cell at the intersection of a particular row and column.
  • The Array form is entered using CTRL + SHIFT + ENTER, instead of just ENTER, as with Reference.

Reference Form of INDEX

  1. Enter the following formula into cell E2 (or any available blank cell):
    =INDEX((A2:C5,A7:C9),2,3,2)
    (A2:C5,A7:C9) are the ranges where the value that you want will be found.

    2 is the row number in the range where the value is.

    3 is the column number in the ranges where the value is. Because there are three columns (beginning with column A), the third column is column C.

    2 is the area, A2:C5 or A7:C9, where the value is. Because there are two areas specified for the range, the second range is A7:C9.
  2. Press ENTER.
In the sample formula, the INDEX function returns a value at the intersection of the second row (2) and third column (C) of the range A7:C9. The value in cell C8 is 23. Therefore, the formula =INDEX((A2:C5,A7:C9),2,3,2) will return the value 23.

Array Form of INDEX

  1. Enter the following formula into cell E3 (or any available blank cell):
    =INDEX(A2:C5,2,3)
    A2:C5 is the range where the value that you want will be found.

    2 is the row number in the range where the value is.

    3 is the column number in the range where the value is. Because there are three columns (beginning with column A), the third column is column C.
  2. Press CTRL+SHIFT+ENTER to enter the formula as an array formula.
In the sample formula, the INDEX function returns a value at the intersection of the second row (2) and third column (C). The value in cell C2 is 19. Therefore, the formula =INDEX(A2:C5,2,3) will return the value 19.
