The INDEX function is one of the lookup and reference functions. It is used to return a value within a range of cells on the base of a specified row and column number. The INDEX function has two forms.
The INDEX function syntax in the array form is:
INDEX(array, [row-number][, [column-number]])
The INDEX function syntax in the reference form is:
INDEX(reference, [row-number][, [column-number][, [area-number]]])
array is a range of cells.
reference is a reference to a range of cells.
row-number is a row number you wish to return a value from. If it is omitted, column-number is required.
column-number is a column number you wish to return a value from. If it is omitted, row-number is required.
area-number is an area to use in case the array contains several ranges. It is an optional argument. If it is omitted, the function will assume area-number to be 1.
These arguments can be entered manually or included into the cells you make reference to.
To apply the INDEX function,
- select the cell where you wish to display the result,
- click the Insert Function icon situated at the top toolbar,
or right-click within a selected cell and select the Insert Function option from the menu,
or click the icon situated at the formula bar,
- select the Lookup and Reference function group from the list,
- click the INDEX function,
- enter the required arguments separating them by commas,
- press the Enter button.
The result will be displayed in the selected cell.
