As a worksheet function, the INDEX function can be entered as part of a formula in a cell of a worksheet. Download Example. 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. 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. The headings have been excluded from these areas.
So, the INDEX function returns the value of the cell, which is at the intersection of the second row and the third column in the area DF This is cell F Further, the number of blank cells of the output range must be equal to the cells of the particular row or column array which is being copied of the source dataset.
This results in a change in the output obtained. The output is the first position found for the given value. Being a lookup and reference function, it works for both an exact and approximate match. For instance, limitations like compulsory sorting of data, restricted size of the lookup value, decreased speed of Excel, and so on are eliminated.
With a change in the value of the last used cell, the output updates on its own. Note 1: Dynamic ranges automatically update with the addition or deletion of data. However, when a cell reference Cell Reference Cell reference in excel is referring the other cells to a cell to use its values or properties. In addition, the row and column numbers of this cell are also specified in the arguments of the INDEX formula.
Both versions have their own set of arguments. For this, take into consideration the kind of data. If an array of values is required, select a blank output range prior to entering the arguments. Next, it returns either a single value or an array of values based on the way it has been used. This is because these functions can easily lookup a value, regardless of the location of the lookup and the return columns. This formula looks for the exact match and returns the row number. But of course we don't want to hardcode any values, so let's update the worksheet to allow the input of a month name, and use MATCH to find the column number we need.
The screen below shows the result:. Note: you could use Data Validation to create dropdown menus to select salesperson and month. Simply put, this just means a lookup where the ID column is to the right of the values you want to retrieve, as seen in the example below:. One of the trickiest problems in Excel is a lookup based on multiple criteria. In other words, a lookup that matches on more than one column at the same time. Skip to main content. Related courses.
Core Formula. Email HP. The EXACT function is the perfect function for this, but the way we use it is a little unusual, because we need to compare one cell to INDEX with variable array.
Max value with variable column. For example, to get the value at row 2 and column This formula pulls the customer name and state from the customer table into the order table. The default behavior of the MATCH function is to match the "next smallest" value in a list that's sorted in ascending order. Name of nth largest value. In other Sum text values like numbers. Get first non-blank value in a list. So, the gist of the problem is this: We want to get the first non-blank cell, but we don't have a direct way to do that in Excel.
Get column name from index in table. The only trick to the formula is the use of a structured reference to return a range for the table headers: Table1[ Headers] This range goes into INDEX for the array argument, with Categorize text with keywords.
