How do I use the INDEX function in Excel?

The INDEX function is a powerful tool in Excel that allows you to look up data from a specific location in a table or range. To use the INDEX function, you'll need to specify the array or table from which you want to retrieve data, and the row and column numbers that indicate the location of the data you want to retrieve.

The syntax for the INDEX function is as follows:

=INDEX(array,row_num,[column_num])

where:

• array: The range of cells or table that contains the data you want to retrieve
• row_num: The row number from which to retrieve the data
• column_num: (optional) The column number from which to retrieve the data. If omitted, the default value is 1

Here is an example:

=INDEX(A1:B10,5,2)

This formula will retrieve the value in the 5th row and 2nd column of the range A1:B10.
