INDEX Function(WS)

Description

The Microsoft Excel INDEX function returns a value in a table based on the intersection of a row and column position within that table. The first row in the table is row 1 and the first column in the table is column 1.

Syntax

The syntax for the INDEX function in Microsoft Excel is:
INDEX( table, row_number, column_number )

Parameters or Arguments

table
A range of cells that contains the table of data.
row_number
The row position in the table where the value you want to lookup is located. This is the relative row position in the table and not the actual row number in the worksheet.
column_number
The column position in the table where the value you want to lookup is located. This is the relative column position in the table and not the actual column number in the worksheet.

Applies To

  • Excel 2016, Excel 2013, Excel 2011 for Mac, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000

Type of Function

  • Worksheet function (WS)

Example (as Worksheet Function)

Let's explore how to use INDEX as a worksheet function in Microsoft Excel.
Excel INDEX function
Based on the Excel spreadsheet above, the following INDEX examples would return:
=INDEX(A2:D6,1,1)
Result: 10247     'Intersection of row1 and col1 (cell A2)

=INDEX(A2:D6,1,2)
Result: "Apples"  'Intersection of row1 and col2 (cell B2)

=INDEX(A2:D6,1,3)
Result: $14.00    'Intersection of row1 and col3 (cell C2)

=INDEX(A2:D6,1,4)
Result: 12        'Intersection of row1 and col4 (cell D2)

=INDEX(A2:D6,2,1)
Result: 10249     'Intersection of row2 and col1 (cell A3)

=INDEX(A2:D6,5,2)
Result: Grapes    'Intersection of row5 and col2 (cell B6)
Now, let's look at the example =INDEX(A2:D6,1,1) that returns a value of 10247 and take a closer look why.

First Parameter

The first parameter in the INDEX function is the table or the source of data where the lookup should be performed.

In this example, the first parameter is A2:D6 which defines the range of cells that contains the data.

Second Parameter

The second parameter is the row number used to determine the intersection location in the table. A value of 1 indicates the first row in the table, a value of 2 is the second row, and so on.

In this example, the second parameter is 1 so we know that our intersection will occur in the first row in the table.

Third Parameter

The third parameter is the column number used to determine the intersection location in the table. A value of 1 indicates the first column in the table, a value of 2 is the second column, and so on.

In this example, the third parameter is 1 so we know that our intersection will occur in the first column in the table.
Since we now have our row and column values, we know that we are looking for the intersection of row1 and col1 in the table of data. This makes the intersection point occur at cell A2 in the table so the INDEX function will return the value 10247.
