## Sort a list in random order in excel

### Overview

The array formula in cell range C2:C6 creates a random list from the values in cell range A2:A6.

### Array formula in C2:

**$C$1:C1**, List)<>COUNTIF(List, List)), RANDBETWEEN(1, SUM(--(COUNTIF(

**$C$1:C1**, List)<>COUNTIF(List, List)))))) + CTRL + SHIFT + ENTER.

### How to create an array formula

- Copy (Ctrl + c) and paste (Ctrl + v) array formula into formula bar.
- Press and hold Ctrl + Shift.
- Press Enter once.
- Release all keys.

Copy cell C2 and paste it down as far as needed.

### How this formula works in cell C2

**Step 1 - Create an array of row numbers from the named range List**

=INDEX(List, LARGE(**(ROW(List)-MIN(ROW(List))+1)***(COUNTIF($C$1:C1, List)<>COUNTIF(List, List)), RANDBETWEEN(1, SUM(--(COUNTIF($C$1:C1, List)<>COUNTIF(List, List))))))

ROW(reference) returns the rownumber of a reference

(ROW(List)-MIN(ROW(List))+1)

becomes

(ROW(A2:A6)-MIN(ROW(A2:A6))+1)

becomes

{2;3;4;5;6}-MIN(ROW({2;3;4;5;6}))+1

becomes

{2;3;4;5;6}-2+1

becomes

{1;2;3;4;5}

**Step 2 - Check value frequency**

=INDEX(List, LARGE((ROW(List)-MIN(ROW(List))+1)***(COUNTIF($C$1:C1, List)<>COUNTIF(List, List))**, RANDBETWEEN(1, SUM(--(COUNTIF($C$1:C1, List)<>COUNTIF(List, List))))))

COUNTIF(range,criteria) counts the number of cells within a range that meet the given condition

(COUNTIF($C$1:C1, List)<>COUNTIF(List, List))

becomes

(COUNTIF("Random list", {"AA";"DD";"CC";"DD";"EE"})<>COUNTIF(List, List))

becomes

{0;0;0;0;0}<>COUNTIF({"AA";"DD";"CC";"DD";"EE"}, {"AA";"DD";"CC";"DD";"EE"})

becomes

{0;0;0;0;0}<>{1;2;1;2;1}

and returns

{TRUE; TRUE; TRUE; TRUE; TRUE}

**Step 3 - Calcultate randbetween arguments**

=INDEX(List, LARGE((ROW(List)-MIN(ROW(List))+1)*(COUNTIF($C$1:C1, List)<>COUNTIF(List, List)), **RANDBETWEEN(1, SUM(--(COUNTIF($C$1:C1, List)<>COUNTIF(List, List)))**)))

RANDBETWEEN(bottom, top) returns a random number between the numbers you specify.

RANDBETWEEN(1, SUM(--(COUNTIF($C$1:C1, List)<>COUNTIF(List, List)))))

becomes

RANDBETWEEN(1, SUM(--({0;0;0;0;0}<>{1;2;1;2;1}))))

becomes

RANDBETWEEN(1, SUM(--({TRUE; TRUE; TRUE; TRUE; TRUE}))))

becomes

RANDBETWEEN(1, SUM({1; 1; 1; 1; 1})))

becomes

RANDBETWEEN(1, 5)

and returns a random number between 1 and 5.

**Step 4 - Select a random row number**

=INDEX(List, LARGE((ROW(List)-MIN(ROW(List))+1)*(COUNTIF($C$1:C1, List)<>COUNTIF(List, List)), RANDBETWEEN(1, SUM(--(COUNTIF($C$1:C1, List)<>COUNTIF(List, List))))))

LARGE(array,k) returns the k-th largest row number in this data set.

becomes

=INDEX(List,LARGE({1;2;3;4;5}, 1))

becomes

=INDEX({"AA";"DD";"CC";"DD";"EE"}, LARGE({1;2;3;4;5}, 1))

and returns EE in cell C2. (random)

### How to customize the formula to your excel spreadsheet

Change the named ranges. If your random list starts at cell F2, change cell reference* ***C1:$C$1** in the above formula to $F$1:F1.

### Named ranges

*List *(A2:A6)

What is named ranges?

Hey can you do the opposite of this - not random order but this is my situation.

i have 3 rows

A1 - Item Number

B1 - Description

C1 - Price

These will constantly be having new numbers put in. is there a way to have it when you add a number into the A coloum it will automatically sort into numerical order? Or can i create a button that after i input all my data click it and it updates all 3 rows into the numberical order based on row A

awall,
