## How to Randomize a List in Excel Without Duplicates: 4 Ways

To begin with, let’s assume the **List of Stock Prices **dataset shown in the **B4:C13 **cells contains the *“Company”* names and the *“Stock Prices” *in USD. Here, we want to return a random *“Company”* name from the list using various functions in Excel. Henceforth, let’s see each method on how to randomize a list in Excel without creating duplicates, with the appropriate illustrations.

Here, we have used the *Microsoft Excel 365* version; you may use any other version according to your convenience.

### 1. Using INDEX, SORTBY, and SEQUENCE Functions (Applicable for Latest Excel Versions)

First of all, let’s start by combining the **INDEX**, **SORTBY**, **RANDARRAY**, **ROWS**, and **SEQUENCE** functions, which collectively select 3 random *“Companies”* from the list shown in the **B4:B13** cells.

📌 ** Steps**:

- Initially, move to the
**B16**cell >> enter the expression given below.

`=INDEX(SORTBY(B5:B13, RANDARRAY(ROWS(B5:B13))), SEQUENCE(3))`

Here, the **B5:B13** array refers to the *“Company”* names.

**Formula Breakdown:**

**ROWS(B5:B13) →**returns the total row numbers in the given range.**Output → 9**

**RANDARRAY(ROWS(B4:B12)) →**returns an array of random numbers, in this case, 9 arrays. Here, the**ROWS(B4:B12)**is the optionalargument.*rows***Output → {0.278134626212438;0.148720604883087;0.355282358043423;0.036883208689009;0.832535669722357;0.927487306458828;0.223257349246205;0.241979490824856;0.100170115552212}**

**SORTBY(B4:B12, RANDARRAY(ROWS(B4:B12))) →**sorts a range or array based on the values in the corresponding range or arrays. Here, the**B4:B12**is theargument while the*array***RANDARRAY(ROWS(B4:B12))**is theargument.*by_array_1***Output → {“Amazon”;”Microsoft”;”Johnson & Johnson”;”Procter & Gamble”;”Oracle”;”TSMC”;”Chevron”;”Apple”;”Toyota”}**

**SEQUENCE(3) →**returns a sequence of numbers. Here,**3**is theargument.*rows***Output → {1;2;3}**

**=INDEX(SORTBY(B5:B13, RANDARRAY(ROWS(B5:B13))), SEQUENCE(3)) →**returns a value at the intersection of a row and column in a given range. In this expression, the**SORTBY(B5:B13, RANDARRAY(ROWS(B5:B13)))**is theargument while the*array***SEQUENCE(3)**is theargument that indicates the row location.*row_num***Output →****{“Chevron”, “Procter & Gamble”, “Toyota”}**

*📃** Note: This formula works for the Excel 365 and Excel 2021 versions, in case you’re using an older version of Excel, you can apply the next method.*

Boom! That’s how easy it is! This returns a randomized list in Excel without any duplicates.

### 2. Utilizing INDEX, RANK.EQ, and COUNTIF Functions (Compatible with Older Version)

Alternatively, we can combine the **RAND**, **INDEX**, **RANK.EQ**, and **COUNTIF** functions to obtain a randomized list of the *“Company”* names. So just follow along.

- First, go to the
**C5**cell >> use the**RAND**function to generate a random value >> use the**Fill Handle**tool to copy the formula into the cells below.

- Second, select the
**C5:C13**cells >> press**CTRL + C**keys to copy the values.

- Third, choose the
**C5:C13**cells >> click the**Paste**drop-down >> select the**Paste Values**option.

- Finally, navigate to the
**B16**cell >> type in the following expression.

`=INDEX($B$5:$B$13,RANK.EQ(C5,$C$5:$C$13)+COUNTIF($C$5:C5,C5)-1,1)`

In this case, the **B5:B13** and **C5:C13** ranges represent the *“Company”* and the *“Random Values”* respectively while the **C5** cell points to the first *“Random Value”*.

**Formula Breakdown:**

**RANK.EQ(C5,$C$5:$C$13)**→ returns the rank of a value in a list of numbers. Here, the**C5**cell is theargument while the*number***$C$5:$C$13**range refers to theargument.*ref***Output → 9**

**COUNTIF($C$5:C5,C5) →**counts the number of cells within a range that meet the given condition. Here, the**$C$5:C5**cells represent theargument that refers to the first*range**“Random Value”*, while the**C5**cell indicates theargument that returns the count of the matched value.*criteria***Output → 1**

**INDEX($B$5:$B$13,RANK.EQ(C5,$C$5:$C$13)+COUNTIF($C$5:C5,C5)-1,1) →**In this expression, the**$B$5:$B$13**is theargument which is the*array**“Company”*name. Next,**RANK.EQ(C5,$C$5:$C$13)+COUNTIF($C$5:C5,C5)-1**is theargument that indicates the row location. Lastly,*row_num***1**is the optionalargument that points to the column location.*column_num***Output → “Oracle”**

📃 *Note: **Please make sure to use **Absolute Cell Reference** by pressing the F4 key on your keyboard.*

### 3. Employing RAND, INDEX, and RANK.EQ Functions

Conversely, a simpler way involves using the **RAND**, **INDEX**, and **RANK.EQ** functions to retrieve 3 of the *“Company”* names at random.

📌 ** Steps**:

- To start with,
**follow the steps shown previously**or the GIF to copy and paste the values in the*“Random Value”*column.

- Afterward, enter the
**B16**cell >> insert the expression into the**Formula Bar**.

`=INDEX($B$5:$B$13,RANK.EQ(C5,$C$5:$C$13),1)`

For instance, the **B5:B13** and **C5:C13** range of cells indicate the *“Company”* and the *“Random Values”* and the **C5** cell represents the initial *“Random Value”*.

**Formula Breakdown:**

**RANK.EQ(C5,$C$5:$C$13)**→ here, the**C5**cell is theargument while the*number***$C$5:$C$13**range refers to theargument.*ref***Output → 7**

**INDEX($B$5:$B$13,RANK.EQ(C5,$C$5:$C$13),1) →**in this expression, the**$B$5:$B$13**is theargument which is the*array**“Company”*name. Next,**RANK.EQ(C5,$C$5:$C$13)**is theargument that indicates the row location. Lastly,*row_num***1**is the optionalargument that points to the column location.*column_num***Output → “Chevron”**

### 4. Applying UNIQUE, RANDARRAY, INDEX, and RANK.EQ Functions

Last but not least, we also apply the **UNIQUE**, **RANDARRAY**, **INDEX**, **RANK.EQ** functions to fetch a list of random values in Excel. So, let’s see it in action.

📌 ** Steps**:

- First of all, click the
**C5**cell >> insert the following formula.

`=UNIQUE(RANDARRAY(9,1,1,9))`

In the above formula, **9** is the row number, **1** is the column number, **1** is the minimum number, and **9** is the maximum number. Next, the **UNIQUE **function ensures that the **RANDARRAY** function returns an array of unique numbers.

📃 *Note: **To stop the C5:C13 array from changing, copy and paste only the values or follow the steps shown in the prior method.*

- Following this, apply the following equation to the
**B16**cell.

`=INDEX($B$5:$B$13,RANK.EQ(C5,$C$5:$C$13),1)`

In this scenario, the **B5:B13** and **C5:C13** range point to the *“Company”* and the *“Random Values”*.

Subsequently, this concludes the process of how to a randomize list in Excel without duplicates.

## How to Randomly Select from a List with No Duplicates in Excel

For one thing, we can choose entire rows at random from a list, on this occasion, we can obtain the *“Company”* names and their corresponding *“Stock Prices”* using the **SORTBY**, **RANDARRAY**, **INDEX**, **SEQUENCE, **and **ROWS** functions.

📌 ** Steps**:

- At the very beginning, click to enter the
**B16**cell >> copy and paste the equation given below.

`=INDEX(SORTBY(B5:C13, RANDARRAY(ROWS(B5:C13))), SEQUENCE(3), {1,2})`

**Formula Breakdown:**

**ROWS(B5:C13) → 9****RANDARRAY(ROWS(B5:C13)) →**here, the**ROWS(B5:C13)**is the optionalargument.*rows***Output → {0.0140698270891861;0.336601258084547;0.302828885068347;0.458536948594194;0.349731499694981;0.188127312170481;0.901260642146929;0.455208105393427;0.480186486777415}**

**SORTBY(B5:C13, RANDARRAY(ROWS(B5:C13)))****→**here, the**B5:C13**is theargument and the*array***RANDARRAY(ROWS(B5:C13))**is theargument.*by_array_1***Output → {“TSMC”,81.75;”Toyota”,154.17;”Amazon”,106.21;”Apple”,136.72;”Microsoft”,256.83;”Procter & Gamble”,143.79;”Johnson & Johnson”,177.51;”Chevron”,144.78;”Oracle”,69.87}**

**SEQUENCE(3) →**here,**3**is theargument.*rows***Output → {1;2;3}**

**INDEX(****SORTBY(B5:C13, RANDARRAY(ROWS(B5:C13))), SEQUENCE(3), {1,2}****) →**in this expression, the**SORTBY(B5:C13, RANDARRAY(ROWS(B5:C13)))**is theargument while the*array***SEQUENCE(3)**and**{1,2}**are theand*row_num*arguments indicating the row and column locations respectively.*col_num*

## How to Randomly Select with Criteria in Excel

Moreover, Excel enables us to randomly select values based on set criteria. For instance, we’ll use the **INDEX**, **LARGE**, **IF**, **ROW**, **INT**, **RAND**, and **COUNTIF **functions to calculate the *“Company”* with a *“Stock Price”* worth more than *“$150 USD”*.

📌 ** Steps**:

- In the first place, enter the
**C16**cell >> insert the expression given below.

`=INDEX(B5:B13,LARGE(IF(C5:C13>150,ROW(C5:C13)-ROW(C5)+1),INT(RAND()*COUNTIF(C5:C13,">150")+1)))`

**Formula Breakdown:**

**IF(C5:C13>150,ROW(C5:C13)-ROW(C5)+1) →**checks whether a condition is met and returns one value if**TRUE**and another value if**FALSE**. Here,**C5:C13>150**is theargument that compares the values in the*logical_test***C5:C13**range with**150**. If this value is greater than or equal to**150**then the function returns**ROW(C5:C13)-ROW(C5)+1)**(argument) otherwise it returns*value_if_true***Blank**(argument).*value_if_false***Output → {FALSE;2;3;FALSE;FALSE;FALSE;FALSE;8;FALSE}**

**COUNTIF(C5:C13,”>150″) →**here, the**C5:C13**cells represent theargument that refers to the*range**Stock Prices*, while**“>150”**indicates theargument that returns the count of the matched value.*criteria***Output → 3**

**INT(RAND()*COUNTIF(C5:C13,”>150″)+1) →**rounds a number down to the nearest integer. Here,**RAND()*COUNTIF(C5:C13,”>150″)+1**is theargument.*number***0.305982491187225 * 3 + 1 → 3**

**LARGE(IF(C5:C13>150,ROW(C5:C13)-ROW(C5)+1),INT(RAND()*COUNTIF(C5:C13,”>150″)+1))→**returns the k-th largest in a dataset. Here,**IF(C5:C13>150,ROW(C5:C13)-ROW(C5)+1)**is theargument while the*array***INT(RAND()*COUNTIF(C5:C13,”>150″)+1)**is the*k-th***Output → 8**

**INDEX(B5:B13,LARGE(IF(C5:C13>150,ROW(C5:C13)-ROW(C5)+1),INT(RAND()*COUNTIF(C5:C13,”>150″)+1))) →**In this expression, the**B5:B13**is theargument which is the*array**“Company”*name. Next,**LARGE(IF(C5:C13>150,ROW(C5:C13)-ROW(C5)+1),INT(RAND()*COUNTIF(C5:C13,”>150″)+1))**is theargument that indicates the row location.*row_num***Output → “Toyota”**

*📃** Note: In the *

*Microsoft Excel 365 version**, you can run the array formula by pressing the*

**ENTER**key. But, in the older versions of Excel, you must press**CTRL + SHIFT + ENTER**to use the array formula.Admittedly, some of the Methods to randomly select with criteria have been skipped, which you may explore if you wish.

## How to Make Unique Random Number Generator in Excel
