Syntax of the INDEX function
The INDEX function allows you to return the entry in any row and column within an array of numbers. The most commonly used syntax for the INDEX function is the following:
INDEX(Array,Row Number,Column Number)
To illustrate, the formula INDEX(A1:D12,2,3) returns the entry in the second row and third column of the array A1:D12. This entry is the one in cell C2.
