The INDEX function returns a value or the reference to a value from within a table or range.
There are two ways to use the INDEX function:
-
If you want to return the value of a specified cell or array of cells, see Array form.
-
If you want to return a reference to specified cells, see Reference form.
Array form
Description
Returns the value of an element in a table or an array, selected by the row and column number indexes.
Use the array form if the first argument to INDEX is an array constant.
Syntax
INDEX(array, row_num, [column_num])
The array form of the INDEX function has the following arguments:
-
array Required. A range of cells or an array constant.
-
If array contains only one row or column, the corresponding row_num or column_num argument is optional.
-
If array has more than one row and more than one column, and only row_num or column_num is used, INDEX returns an array of the entire row or column in array.
-
-
row_num Required, unless column_num is present. Selects the row in array from which to return a value. If row_num is omitted, column_num is required.
-
column_num Optional. Selects the column in array from which to return a value. If column_num is omitted, row_num is required.
Remarks
-
If both the row_num and column_num arguments are used, INDEX returns the value in the cell at the intersection of row_num and column_num.
-
row_num and column_num must point to a cell within array; otherwise, INDEX returns a #REF! error.
-
If you set row_num or column_num to 0 (zero), INDEX returns the array of values for the entire column or row, respectively. To use values returned as an array, enter the INDEX function as an array formula.
Note: If you have a current version of Microsoft 365, then you can input the formula in the top-left-cell of the output range, then press ENTER to confirm the formula as a dynamic array formula. Otherwise, the formula must be entered as a legacy array formula by first selecting the output range, input the formula in the top-left-cell of the output range, then press CTRL+SHIFT+ENTER to confirm it. Excel inserts curly brackets at the beginning and end of the formula for you. For more information on array formulas, see Guidelines and examples of array formulas.

Reference form
Description
Returns the reference of the cell at the intersection of a particular row and column. If the reference is made up of non-adjacent selections, you can pick the selection to look in.
Syntax
INDEX(reference, row_num, [column_num], [area_num])
The reference form of the INDEX function has the following arguments:
-
reference Required. A reference to one or more cell ranges.
-
If you are entering a non-adjacent range for the reference, enclose reference in parentheses.
-
If each area in reference contains only one row or column, the row_num or column_num argument, respectively, is optional. For example, for a single row reference, use INDEX(reference,,column_num).
-
-
row_num Required. The number of the row in reference from which to return a reference.
-
column_num Optional. The number of the column in reference from which to return a reference.
-
area_num Optional. Selects a range in reference from which to return the intersection of row_num and column_num. The first area selected or entered is numbered 1, the second is 2, and so on. If area_num is omitted, INDEX uses area 1. The areas listed here must all be located on one sheet. If you specify areas that are not on the same sheet as each other, it will cause a #VALUE! error. If you need to use ranges that are located on different sheets from each other, it is recommended that you use the array form of the INDEX function, and use another function to calculate the range that makes up the array. For example, you could use the CHOOSE function to calculate which range will be used.
For example, if Reference describes the cells (A1:B4,D1:E4,G1:H4), area_num 1 is the range A1:B4, area_num 2 is the range D1:E4, and area_num 3 is the range G1:H4.
Remarks
-
After reference and area_num have selected a particular range, row_num and column_num select a particular cell: row_num 1 is the first row in the range, column_num 1 is the first column, and so on. The reference returned by INDEX is the intersection of row_num and column_num.
-
If you set row_num or column_num to 0 (zero), INDEX returns the reference for the entire column or row, respectively.
-
row_num, column_num, and area_num must point to a cell within reference; otherwise, INDEX returns a #REF! error. If row_num and column_num are omitted, INDEX returns the area in reference specified by area_num.
-
The result of the INDEX function is a reference and is interpreted as such by other formulas. Depending on the formula, the return value of INDEX may be used as a reference or as a value. For example, the formula CELL(«width»,INDEX(A1:B2,1,2)) is equivalent to CELL(«width»,B1). The CELL function uses the return value of INDEX as a cell reference. On the other hand, a formula such as 2*INDEX(A1:B2,1,2) translates the return value of INDEX into the number in cell B1.

- Пример 4. Использование трехстороннего поиска с помощью INDEX (ИНДЕКС) / MATCH (ПОИСКПОЗ)
Что возвращает функция
Возвращает данные из конкретной строки и столбца табличных данных.
Синтаксис
=INDEX (array, row_num, [col_num]) — английская версия
=INDEX (array, row_num, [col_num], [area_num]) — английская версия
=ИНДЕКС(массив; номер_строки; [номер_столбца]) — русская версия
=ИНДЕКС(ссылка; номер_строки; [номер_столбца]; [номер_области]) — русская версия
Аргументы функции
- array (массив) — диапазон ячеек или массив данных для поиска;
- row_num (номер_строки) — номер строки, в которой находятся искомые данные;
- [col_num] ([номер_столбца]) (необязательный аргумент) — номер колонки, в которой находятся искомые данные. Этот аргумент необязательный. Но если в аргументах функции не указаны критерии для row_num (номер_строки), необходимо указать аргумент col_num (номер_столбца);
- [area_num] ([номер_области]) — (необязательный аргумент) — если аргумент массива состоит из нескольких диапазонов, то это число будет использоваться для выбора всех диапазонов.
Дополнительная информация
- Если номер строки или колонки равен “0”, то функция возвращает данные всей строки или колонки;
- Если функция используется перед ссылкой на ячейку (например, A1), она возвращает ссылку на ячейку вместо значения (см. примеры ниже);
- Чаще всего INDEX (ИНДЕКС) используется совместно с функцией MATCH (ПОИСКПОЗ);
- В отличие от функции VLOOKUP (ВПР), функция INDEX (ИНДЕКС) может возвращать данные как справа от искомого значения, так и слева;
- Функция используется в двух формах — Массива данных и Формы ссылки на данные:
— Форма «Массива» используется когда вы хотите найти значения, основанные на конкретных номерах строк и столбцов таблицы;
— Форма «Ссылок на данные» используется при поиске значений в нескольких таблицах (используете аргумент [area_num] ([номер_области]) для выбора таблицы и только потом сориентируете функцию по номеру строки и столбца.
Примеры использования функции ИНДЕКС в Excel
Пример 1. Ищем результаты экзамена по физике для Алексея
Предположим, у вас есть результаты экзаменов в табличном виде по нескольким студентам:
Для того, чтобы найти результаты экзамена по физике для Андрея нам нужна формула:
=INDEX($B$3:$E$9,3,2) — английская версия
=ИНДЕКС($B$3:$E$9;3;2) — русская версия
В формуле мы определили аргумент диапазона данных, где мы будем искать данные $B$3:$E$9. Затем, указали номер строки “3”, в которой находятся результаты экзамена для Андрея, и номер колонки “2”, где находятся результаты экзамена именно по физике.
Пример 2. Создаем динамический поиск значений с использованием функций ИНДЕКС и ПОИСКПОЗ
Не всегда есть возможность указать номера строки и столбца вручную. У вас может быть огромная таблица данных, отображение данных которой вы можете сделать динамическим, чтобы функция автоматически идентифицировала имя или экзамен, указанные в ячейках, и дала правильный результат.
Пример динамического отображения данных ниже:
Для динамического отображения данных мы используем комбинацию функций INDEX (ИНДЕКС) и MATCH (ПОИСКПОЗ).
Вот такая формула поможет нам добиться результата:
=INDEX($B$3:$E$9,MATCH($G$4,$A$3:$A$9,0),MATCH($H$3,$B$2:$E$2,0)) — английская версия
=ИНДЕКС($B$3:$E$9;ПОИСКПОЗ($G$4;$A$3:$A$9;0);ПОИСКПОЗ($H$3;$B$2:$E$2;0)) — русская версия
В формуле выше, не используя сложного программирования, мы с помощью функции MATCH (ПОИСКПОЗ) сделали отображение данных динамическим.
Динамический отображение строки задается следующей частью формулы —
MATCH($G$4,$A$3:$A$9,0) — английская версия
ПОИСКПОЗ($G$4;$A$3:$A$9;0) — русская версия
Она сканирует имена студентов и определяет значение поиска ($G$4 в нашем случае). Затем она возвращает номер строки для поиска в наборе данных. Например, если значение поиска равно Алексей, функция вернет “1”, если это Максим, оно вернет “4” и так далее.
Динамическое отображение данных столбца задается следующей частью формулы —
MATCH($H$3,$B$2:$E$2,0) — английская версия
ПОИСКПОЗ($H$3;$B$2:$E$2;0) — русская версия
Она сканирует имена объектов и определяет значение поиска ($H$3 в нашем случае). Затем она возвращает номер столбца для поиска в наборе данных. Например, если значение поиска Математика, функция вернет “1”, если это Физика, функция вернет “2” и так далее.

Пример 3. Создаем динамический поиск значений с использованием функций INDEX (ИНДЕКС) и MATCH (ПОИСКПОЗ) и выпадающего списка
На примере выше мы вручную вводили имена студентов и названия предметов. Вы можете сэкономить время на вводе данных, используя выпадающие списки. Это актуально, когда количество данных огромное.
Используя выпадающие списки, вам нужно просто выбрать из списка имя студента и функция автоматически найдет и подставит необходимые данные.
Пример ниже:
Используя такой подход, вы можете создать удобный дашборд, например для учителя. Ему не придется заниматься фильтрацией данных или прокруткой листа со студентами, для того чтобы найти результаты экзамена конкретного студента, достаточно просто выбрать имя и результаты динамически отразятся в лаконичной и удобной форме.
Для того, чтобы осуществить динамическую подстановку данных с использованием функций INDEX (ИНДЕКС) и MATCH (ПОИСКПОЗ) и выпадающего списка, мы используем ту же формулу, что в Примере 2:
=INDEX($B$3:$E$9,MATCH($G$4,$A$3:$A$9,0),MATCH($H$3,$B$2:$E$2,0)) — английская версия
=ИНДЕКС($B$3:$E$9;ПОИСКПОЗ($G$4;$A$3:$A$9;0);ПОИСКПОЗ($H$3;$B$2:$E$2;0)) — русская версия
Единственное отличие, от Примера 2, мы на месте ввода имени и предмета создадим выпадающие списки:
- Выбираем ячейку, в которой мы хотим отобразить выпадающий список с именами студентов;
- Кликаем на вкладку “Data” => Data Tools => Data Validation;
- В окне Data Validation на вкладке “Settings” в подразделе Allow выбираем “List”;
- В качестве Source нам нужно выбрать диапазон ячеек, в котором указаны имена студентов;
- Кликаем ОК
Теперь у вас есть выпадающий список с именами студентов в ячейке G5. Таким же образом вы можете создать выпадающий список с предметами.
Пример 4. Использование трехстороннего поиска с помощью INDEX (ИНДЕКС) / MATCH (ПОИСКПОЗ)
Функция INDEX (ИНДЕКС) может быть использована для обработки трехсторонних запросов.
Что такое трехсторонний поиск?
В приведенных выше примерах мы использовали одну таблицу с оценками для студентов по разным предметам. Это пример двунаправленного поиска, поскольку мы используем две переменные для получения оценки (имя студента и предмет).
Теперь предположим, что к концу года студент прошел три уровня экзаменов: «Вступительный», «Полугодовой» и «Итоговый экзамен».
Трехсторонний поиск — это возможность получить отметки студента по заданному предмету с указанным уровнем экзамена.
Вот пример трехстороннего поиска:
В приведенном выше примере, кроме выбора имени студента и названия предмета, вы также можете выбрать уровень экзамена. Основываясь на уровне экзамена, формула возвращает соответствующее значение из одной из трех таблиц.
Для таких расчетов нам поможет формула:
=INDEX(($B$3:$E$7,$B$11:$E$15,$B$19:$E$23),MATCH($G$4,$A$3:$A$7,0),MATCH($H$3,$B$2:$E$2,0),IF($H$2=»Вступительный»,1,IF($H$2=»Полугодовой»,2,3))) — английская версия
=ИНДЕКС(($B$3:$E$7;$B$11:$E$15;$B$19:$E$23);ПОИСКПОЗ($G$4;$A$3:$A$7;0);ПОИСКПОЗ($H$3;$B$2:$E$2;0); ЕСЛИ($H$2=»Вступительный»;1;ЕСЛИ($H$2=»Полугодовой»;2;3))) — русская версия
Давайте разберем эту формулу, чтобы понять, как она работает.
Эта формула принимает четыре аргумента. Функция INDEX (ИНДЕКС) — одна из тех функций в Excel, которая имеет более одного синтаксиса.
=INDEX (array, row_num, [col_num]) — английская версия
=INDEX (array, row_num, [col_num], [area_num]) — английская версия
=ИНДЕКС(массив; номер_строки; [номер_столбца]) — русская версия
=ИНДЕКС(ссылка; номер_строки; [номер_столбца]; [номер_области]) — русская версия
По всем вышеприведенным примерам мы использовали первый синтаксис, но для трехстороннего поиска нам нужно использовать второй синтаксис.
Рассмотрим каждую часть формулы на основе второго синтаксиса.
- array (массив) – ($B$3:$E$7,$B$11:$E$15,$B$19:$E$23):Вместо использования одного массива, в данном случае мы использовали три массива в круглых скобках.
- row_num (номер_строки) – MATCH($G$4,$A$3:$A$7,0): функция MATCH (ПОИСКПОЗ) используется для поиска имени студента для ячейки $G$4 из списка всех студентов.
- col_num (номер_столбца) – MATCH($H$3,$B$2:$E$2,0): функция MATCH (ПОИСКПОЗ) используется для поиска названия предмета для ячейки $H$3 из списка всех предметов.
- [area_num] ([номер_области]) – IF($H$2=”Вступительный”,1,IF($H$2=”Полугодовой”,2,3)): Значение номера области сообщает функции INDEX (ИНДЕКС), какой массив с данными выбрать. В этом примере у нас есть три массива в первом аргументе. Если вы выберете «Вступительный» из раскрывающегося меню, функция IF (ЕСЛИ) вернет значение “1”, а функция INDEX (ИНДЕКС) выберут 1-й массив из трех массивов ($B$3:$E$7).
Уверен, что теперь вы подробно изучили работу функции INDEX (ИНДЕКС) в Excel!
The INDEX function returns the value at a given location in a range or array. INDEX is a powerful and versatile function. You can use INDEX to retrieve individual values, or entire rows and columns. INDEX is frequently used together with the MATCH function. In this scenario, the MATCH function locates and feeds a position to the INDEX function, and INDEX returns the value at that position.
In the most common usage, INDEX takes three arguments: array, row_num, and col_num. Array is the range or array from which to retrieve values. Row_num is the row number from which to retrieve a value, and col_num is the column number at which to retrieve a value. Col_num is optional and not needed when array is one-dimensional.
In the example shown above, the goal is to get the diameter of the planet Jupiter. Because Jupiter is the fifth planet in the list, and Diameter is the third column, the formula in G7 is:
=INDEX(B5:E13,5,3) // diameter of Jupiter
The formula above is of limited value because the row number and column number have been hard-coded. Typically, the MATCH function would be used inside INDEX to provide these numbers. For a detailed explanation with many examples, see: How to use INDEX and MATCH.
Basic usage
INDEX gets a value at a given location in a range of cells based on numeric position. When the range is one-dimensional, you only need to supply a row number. When the range is two-dimensional, you’ll need to supply both the row and column number. For example, to get the third item from the one-dimensional range A1:A5:
=INDEX(A1:A5,3) // returns value in A3
The formulas below show how INDEX can be used to get a value from a two-dimensional range:
=INDEX(A1:B5,2,2) // returns value in B2
=INDEX(A1:B5,3,1) // returns value in A3
INDEX and MATCH
In the examples above, the position is «hardcoded». Typically, the MATCH function is used to find positions for INDEX. For example, in the screen below, the MATCH function is used to locate «Mars» (G6) in row 3 and feed that position to INDEX. The formula in G7 is:
=INDEX(B5:E13,MATCH(G6,B5:B13,0),3)
MATCH provides the row number (4) to INDEX. The column number is still hardcoded as 3.
INDEX and MATCH with horizontal table
In the screen below, the table above has been transposed horizontally. The MATCH function returns the column number (4) and the row number is hardcoded as 2. The formula in C10 is:
=INDEX(C4:K6,2,MATCH(C9,C4:K4,0))
For a detailed explanation with many examples, see: How to use INDEX and MATCH
Entire row / column
INDEX can be used to return entire columns or rows like this:
=INDEX(range,0,n) // entire column
=INDEX(range,n,0) // entire row
where n represents the number of the column or row to return. This example shows a practical application of this idea.
Reference as result
It’s important to note that the INDEX function returns a reference as a result. For example, in the following formula, INDEX returns A2:
=INDEX(A1:A5,2) // returns A2
In a typical formula, you’ll see the value in cell A2 as the result, so it’s not obvious that INDEX is returning a reference. However, this is a useful feature in formulas like this one, which uses INDEX to create a dynamic named range. You can use the CELL function to report the reference returned by INDEX.
Two forms
The INDEX function has two forms: array and reference. Both forms have the same behavior – INDEX returns a reference in an array based on a given row and column location. The difference is that the reference form of INDEX allows more than one array, along with an optional argument to select which array should be used. Most formulas use the array form of INDEX, but both forms are discussed below.
Array form
In the array form of INDEX, the first parameter is an array, which is supplied as a range of cells or an array constant. The syntax for the array form of INDEX is:
INDEX(array,row_num,[col_num])
- If both row_num and col_num are supplied, INDEX returns the value in the cell at the intersection of row_num and col_num.
- If row_num is set to zero, INDEX returns an array of values for an entire column. To use these array values, you can enter the INDEX function as an array formula in horizontal range, or feed the array into another function.
- If col_num is set to zero, INDEX returns an array of values for an entire row. To use these array values, you can enter the INDEX function as an array formula in vertical range, or feed the array into another function.
Reference form
In the reference form of INDEX, the first parameter is a reference to one or more ranges, and a fourth optional argument, area_num, is provided to select the appropriate range. The syntax for the reference form of INDEX is:
INDEX(reference,row_num,[col_num],[area_num])
Just like the array form of INDEX, the reference form of INDEX returns the reference of the cell at the intersection row_num and col_num. The difference is that the reference argument contains more than one range, and area_num selects which range should be used. The area_num is argument is supplied as a number that acts like a numeric index. The first array inside reference is 1, the second array is 2, and so on.
For example, in the formula below, area_num is supplied as 2, which refers to the range A7:C10:
=INDEX((A1:C5,A7:C10),1,3,2)
In the above formula, INDEX will return the value at row 1 and column 3 of A7:C10.
- Multiple ranges in reference are separated by commas and enclosed in parentheses.
- All ranges must on one sheet or INDEX will return a #VALUE error. Use the CHOOSE function as a workaround.
This Excel tutorial explains how to use the Excel INDEX function with syntax and examples.
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.
The INDEX function is a built-in function in Excel that is categorized as a Lookup/Reference Function. It can be used as a worksheet function (WS) in Excel. As a worksheet function, the INDEX function can be entered as part of a formula in a cell of a worksheet.

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.
Returns
The INDEX function returns any datatype such as a string, numeric, date, etc.
Applies To
- Excel for Office 365, Excel 2019, 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.
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.

Frequently Asked Questions
What is the INDEX Function in Excel?
The INDEX function in Excel provides the value of a cell within a selected range against a given row and column. For example, the formula = INDEX(“Employee ID”,row_num,[column_num]) will return the Employee ID 27 against the given row number 5 and column number 3.
Using the INDEX function, we can find the value at the intersection of a specific row and column. The INDEX function in Excel is present under the Microsoft Excel Lookup and Reference function.
Key Highlights
- The INDEX function in Excel helps to find the information within a data range, where it looks up values by both columns and rows.
- It looks up the value of a cell at the intersection of a given row and column.
- We use the INDEX function in Excel with the MATCH function more commonly. The combination of the INDEX and MATCH functions is an alternative to the VLOOKUP function, which is more powerful & flexible.
- We can use the INDEX function in Excel to fetch individual values or entire rows and columns.
INDEX Function in Excel Syntax
There are two types of the INDEX function in Excel:
#1 Array Form
We use the Array INDEX form when the cell we refer to is within a single range of the data table, e.g., A3:C7.

= INDEX (array, row_num, [column_num])
#2 Reference Form
We use this INDEX form when the cell that we are referring to is within multiple cell ranges, e.g., (A7:C1,A12:C14,A16:C19)
Refer to the below image-
Syntax-
=INDEX (reference,row_num,[col_num],[area_num])
Explanation of the Syntax
array:
It is a compulsory or required argument that indicates the range or array of cells we want to look up
Note: If there are multiple cell ranges in the data table, it is called a reference where all the cell ranges(areas) are separated by a comma and with closed brackets
row_num:
It is a compulsory or required argument that indicates the row number against which we want to fetch the value.
Note: Excel considers the row_num argument optional if only one row exists in an array or cell range.
col_num:
It is a compulsory or required argument that indicates the column number against which we want to fetch the value.
Note: Excel considers the col_num argument optional if only one column exists in an array or cell range.
area_num:
It is an optional argument. If the desired value is present in multiple cell ranges in the data table, the area_num indicates the cell range to use.
Note: If there is no value in area_num, then by default, the INDEX Function in Excel considers the first area as the area number.

We will apply the INDEX formula in cell B16 to get the Employee ID of Methos.
Step 1: Click on the Insert Function (fx) option under the Formulas section of the Excel toolbar.
An Insert Function dialog box appears.
Step 2: Type INDEX in the dialog box’s Search for a function option. And double click the INDEX option from the list.
A Select Arguments dialog box shows the two types of INDEX functions: one for array and the other for reference.
Step 3: Select the array formula, as we have only one data range, and click OK.
A Function Arguments dialog box opens with options Array, row_num, and column_num.
Step 4: Enter the cell range (A7:D13) that contains the lookup value in the Array argument
Note: Do not select the column headings
Step 5: Enter the row number(5) that contains the lookup value in the row_num argument.
Step 6: Enter the column number(2) that contains the lookup value in the Col_num argument.
Step 7: Click OK to get the below result
The Index function will return the value of the 5th row and 2nd column, i.e., Employee ID 333.
Example #2
The table below shows the Batch ID of Clothing products manufactured by different industries. We want to find the Batch ID of products manufactured by Entech Co. Ltd.
Solution:
Step 1: Write Entech Co. Ltd. in cell A16
Step 2: Place the cursor in cell B16 and enter the formula,
=INDEX(A7:D13,5,4)
Explanation:
A7:D13: It is the cell range that contains data about Entech Co. Ltd.
5,4: The lookup value- Entech Co. Ltd. is in the 5th row of the selected cell range with Batch ID in the 4th column.
Therefore, we write 5 & 4, respectively, in the formula.
Step 3: Press the Enter key to get the below result
The INDEX function with Array Form gives the Batch ID of 205 for products manufactured by Entech Co. Ltd.
Example #3
The table below shows 4 different caterers with snacks they supplied and invoice numbers for their respective bills. Here, we want to find the invoice number for the bill of the snacks supplied by Hungritos.
Solution:
Step 1: Write Hungritos in cell A13
Step 2: Place the cursor in cell B13 and enter the formula,
=INDEX(A7:D10,1,3)
Explanation:
A7:D10- It is the cell range that contains the data of Hingritos.
Note: We do not select the headings of the table.
1,3- The lookup value- Hingritos is in the 1st row of the selected range with invoice no. in the 3rd column. Therefore, we write 1 & 3, respectively, in the formula.
Step 3: Press the Enter key to get the below result
The INDEX function returns invoice no. 51 for snacks provided by Hungritos.
REFERENCE FORM
Example #1
The table below shows three different tables with Employee Name, Employee ID, Gender, Age, and Department. We want to find the Employee ID of Maria using the INDEX function in Excel.
Solution:
Here, we will use the Reference Form of Excel since there are three different data tables.
Step 1: Write Maria in cell E7
Step 2: Place the cursor in cell F7 and type =INDEX(
When we type the above, it displays two arguments, as shown in the image below
Step 3: Enter the formula,
=INDEX((A7:C13,A16:C18,A22:C23),2,2,2)
- Row_num: It is the row against which we want to fetch the Employee ID of Maria present in table 2; therefore, we enter row number(2), the intersection will occur at the 2nd row of the table
- Col_num: It is the column against which we want to fetch the value, i.e., 2, the intersection will occur at the 2nd column of the 2nd table
- Area_num: It indicates the area(table) which contains the details of Maria, i.e., table 2. Thus, we enter the Area_num as number 2 here.
Step 4: Press the Enter key to get the below output
The INDEX function in Excel returns Employee ID of Maria as 627.
Example #2
The table below shows sports items sold by a store with their prices. We want to find the number of Volleyballs sold by the store given the row number and column number.
Solution:
Step 1: Write the desired row and column numbers in cells E7 and F7, respectively.
Step 2: Place the cursor in cell G7 and enter the formula,
=INDEX((A7:C10,A12:C14,A16:C19),2,3,3)
The table above has three different areas- area 1, area 2, and area 3. Our desired item, a Volleyball, is in the third area. Therefore, we write the number 3 at the end.
Step 3: Press the Enter key to give the below result.
Things to Remember
- The INDEX function in Excel returns #VALUE! Error if row_num/ column_num is not mentioned in the formula or given as 0.
- The INDEX function returns #VALUE! error if the values for row_num, col_num, or area_num are non-numeric.
- The INDEX function in Excel returns #REF! Error if the value entered for row_num exceeds the number of rows present in the data table
- The INDEX function returns #REF! Error if the value entered for column_num exceeds the number of columns present in the data table
- The INDEX function in Excel returns #REF! Error if we provide a value for area_num greater than the number of areas in the cell range.
- If we give (refer) the area_num in the INDEX Formula from another sheet, the Index Function in Excel returns #VALUE! Error. It should represent the table present in the same sheet.
Frequently Asked Questions (FAQs)
Q1) What is the use of INDEX ()?
Answer: With the INDEX (), we can find the index position of an element or character in an item string. It gives the lowest possible index of the specified element in the list. If the provided item is not in the list, the INDEX function in Excel returns a ValueError.
Q2) What is the INDEX formula?
Answer: The INDEX formula for the Array form is
=INDEX(array, row_num, [col_num]).
The INDEX formula for Reference form is =INDEX(reference,row_num,[column_num],[area_num]).
The array argument specifies the cell range we want to look up. If there are multiple cell ranges in the data table, we separate them using a comma and close them with brackets; row_num indicates the row number against which we want to fetch the value; col_num indicates the column number against which we want to fetch the value; area_num indicates the range to use if there are multiple areas(tables).
Q3) What is the purpose of the INDEX and MATCH functions?
The INDEX function provides the value of a parameter based on the row and column numbers. The MATCH function gives the position of a cell in a column or a row. Combining the INDEX and MATCH functions provides a cell value based on horizontal and vertical criteria.
