# Find the Closest Data to the Data Provided in Google Sheets

In our daily work, we may encounter such an issue that to **find the closest value to a certain value**. In fact, google sheets internal functions can help us solve this problem. In today’s article, we will show you how to find the student whose score value is closet to the score provided with help of **google sheets INDEX/MATCH/MIN/ABS** functions.

Look at the following example, we want to know who has a score closest to score “**150**” or “**100**”.

**GENERAL FORMULA IN GOOGLE SHEETS**

The general formula for this case is

=INDEX(Data,MATCH(MIN(ABS(Data-ProvideValue)),ABS(Data-ProvideValue),0))

In the general formula, you can replace **Data **and **ProvideData** with your own range or data reference. This is an array formula and we need to press “c**ontrol + shift + enter**” after entering the formula in google sheets .

In the above example, the formula is

=INDEX(Student,MATCH(MIN(ABS(Score-D2)),ABS(Score-D2),0)).

In the formula, Data is “Student” list (A2:A9, named “Student”); there are two provided values, 150 in D2 and 100 in D3; In this example, we want to find the closest score to the provided score (in D2 and D3) from the “Scores” list and retrieve the matching student name from the “Students” list that will be returned by the formula and filled in correctly in E2 and E3. Enter above formula in C8, then copy down the formula, the matching students are filled in properly.

**Notes:**

If we want to only obtain the score value instead of the student, we can just change the lookup array from Student to Score in this formula.

=INDEX(Score,MATCH(MIN(ABS(Score-D2)),ABS(Score-D2),0))

** ****EXPLANATION**

For the formula, the core is the usage of **google sheets INDEX** and **MATCH** functions combination. Before we can explain this formula, we need to know these two functions.

**MATCH** is an google sheets function for locating the position of a query value in a row, column, or table. **INDEX** is used to return the value at a certain position. As you can see, the **MATCH** function can provide a relative position of a value within a range, and **INDEX** can provide a suitable value based on the position provided, so typically, the **MATCH** and **INDEX** functions are used together to retrieve a value at a matching position.

**Syntax:**

=MATCH(lookup_value, lookup_array, [match_type]) (match type 0=exact match) =INDEX(array, row_num, [column_num])

In this example, using E2 as an example, we want to return the name of the student whose score retrieved from the student list is closest to the score 150 provided in D2, so for **INDEX** function in this formula, the array is the named range “Student” (A2:A9). We expand this array in the formula bar, the array is generated:

{"Danni";"Michelle";"Riya";"Emilia";"Nova";"Ari";"Leo";"Maren"}

In this **INDEX** function, the parameter “**row_number**” is obtained by executing another **google sheets MATCH** function. **MATCH** function will delivery its result to** INDEX** as row number. The hard work in this case is to find the closest score in Score list to the data provided in D column and obtain the relative position of this score in Score list. To resolve this issue, we use **google sheets ABS** and **MIN** functions in **MATCH** expression to obtain the minimum difference between the data and the data provided, and with their help, **MATCH** function can return the position of the closest score. To let you know how it works step by step, we will explain the expression from inside to outside as the result of the internal function will be delivered to the external one.

First, let’s get to know what the role **ABS** and **MIN** functions play in **MATCH** function.

** ****ABS Function **is used to return the absolute value of an integer.

**Syntax:**

=ABS(value)

** ****MIN Function** is used to return the smallest value in supplied data

**Syntax:**

=MIN(number1, [number2], ...)

** **In this example, **MIN(ABS(Score-D2))** is the lookup value of the **MATCH** function. **ABS(Score-D2)** is the lookup array. Match type is 0, so the **MATCH** function returns an exact match.

**Notes:**

We all know that the smaller the difference between two values, the closer the two numbers are to each other. **ABS(Score-D2)** provides an array that save the differences between each value in “Score” and the value provided in D2, the differences may be negative or positive, but **ABS** function will convert the negative ones to positive numbers, so this function returns an array only contains positive numbers; And **MIN(ABS(Score-D2)) **provides the smallest difference among all differences.

** **For **ABS(Score-D2)**, since the values saved in “Score” are vertically aligned, “Score” is a vertical array.; so **(Score-D2) **is also a vertical array. This step is done to get the difference between the two values.

Expand Score and D2 in the formula bar:

**Score: ****{134;142;110;96;120;98;144;108}**

**D2:150**

Calculate** (Score-D2) **in google sheets formula bar and get below array:

{-16;-8;-40;-54;-30;-52;-6;-42}

Use **google sheets ABS** function to convert all negative numbers to positive numbers.

**{16;8;40;54;30;52;6;42} – This array is the lookup array for MATCH function**

For **MIN(ABS(Score-D2))**, the result of **ABS** function (numbers in the array above) is also delivered to **MIN **function:

**=MIN({16;8;40;54;30;52;6;42})**

The **google sheets MIN** function will extract the smallest value in the array.

Now, for **MATCH** function, the lookup value and lookup array are obtained after calculating **ABS **and **MIN** expressions.

**=MATCH(6,{16;8;40;54;30;52;6;42},0)**

As mentioned above, **google sheets MATCH** function returns the position of a certain value, so in this case, **MATCH** function returns the row number of value “6” in array {16;8;40;54;30;52;6;42}. Obviously, relative to this array, 6 is in row 7.

Now we come to the outermost **INDEX** function：

=INDEX({"Danni";"Michelle";"Riya";"Emilia";"Nova";"Ari";"Leo";"Maren"},7)

In this formula, **MATCH** function delivered row number 7 to **INDEX **function, **INDEX** function returns a value in an array based on a provided row number. In this array which consists of student names, the seventh name is “Leo”, so this is the final result for this formula. After entering “**Ctrl+Shift+Enter**”, “Leo” is displayed in cell E2.

Copied down the formula to E2, we can obtain “Ari” in the same way.

This article not only introduces the joint application of **INDEX **and **MATCH**, but also the use of **MIN** and **ABS** functions, including how to apply the combination of **MIN** and** ABS** functions to find the minimum difference between values in google sheets . Readers can design their own formulas according to the actual situation.
