## Split values equally into groups using excel array formula

*Article updated on August 28, 2017*

**Question:**How do I divide values equally into groups (3 lists or less)?

This post shows you two different approaches, a User Defined Function and an array formula. So which one should you use, I recommend using the UDF.

It is easier to use in this case while the array formula needs a little tweaking to get the right number of groups.

### User defined function

You decide how many groups you want by selecting a cell range with as many columns as you want groups and then enter the UDF. It is designed to group values depending on how many columns you have selected before entering it.

The animated picture above shows you a cell range with 5 columns.

**How to enter an array formula**

- Select cell range C2:G11
- Paste above array formula to your formula bar

- Press and hold CTRL and SHIFT keys simultaneously
- Press Enter once

The formula in the formula bar now looks like this: {=GroupValues(A2:A24)}

Don't enter these curly parentheses yourself, they appear automatically if you did the above steps correctly.

Array formulas allows you to do advanced calculations not possible with regular formulas.

**VBA code**

Function GroupValues(rng As Range) Dim result As Variant c = Application.Caller.Columns.Count r = Application.Caller.Rows.Count ReDim result(1 To r, 1 To c) i = 1 For ro = 1 To r For co = 1 To c If rng.Cells(i) <> "" Then result(ro, co) = rng.Cells(i) Else result(ro, co) = "" End If i = i + 1 Next co Next ro GroupValues = result End Function

i tried to add a list number 4 with this formula =IF(D1>3,INDEX($A$2:$A$21,(ROW($A$2:$A$21)-MIN(ROW($A$2:$A$21))+1)*D1-(D1-4)),"")

the value at f4 is DD but the f5, f6,etc....arejust repeating the result

Fahmy,

Hi Oscar, thanks for the great tutorial.

I was hoping to use what you've described above but for data that stretches across a single row.

For example, if I have data that stretches from A1:J1, I would like to split it up into 5 rows so that I would have the values appear in A2:B2, A3:B3, A4:B4,A5:B5, A6:B6.

I have taken a stab at manipulating the formulas you've provided but with no luck. Was hoping you could help out!

Thanks!

Hasan,

Array formula in cell range: A2:E3:

A2:E3))+1)+(ROWS(A2:E3)*(COLUMN()-1))),"")How to create array formula

1. Select cell range A2:E3

2. Paste formula in formula bar

3. Press and hold Ctrl + Shift

4. Press Enter

Adjust bolded cell ranges if you enter the array formula in a different cell range.

HI Oscar! I would need your help to strech column A to 500 rows with 8 lists. Thanks!

Hey, quick question, would this beable to expand into say a list of 100 values and have 10 groups. ive tried editing the code but am unsuccessful in getting the formula to work correctly

Here is a workbook for you:

split-values-into-groups-using-excel-formulav2.xlsx

Hi Oscar, I wonder if you could help, I have a large number of record numbers (basically a call list for a sales office) which I need to split up into equal lists, there could be between 100 and about 400 items.

I have tried to use your example spreadsheet and replace the ranges with dynamic named ranges (which are set up contain all the record numbers), but that gives me a #VALUE error, even if I use crtl+alt+enter.

In addition, I cannot seem to make the lists in your example longer to accommodate this, if I copy and paste the formula downward, I get one record number repeated.

Here is a link to my spreadsheet on google drive (I am using excel 2013 - just using google drive to host the file!) I would really appreciate it if you could have a look and let me know where I'm going wrong...

Cheers!

Joe,

I have built a user defined function that is easier to use, read this post again.

Hi Oscar, Thank you so much, this is much easier, thankyou!

Hi Oscar! Thank you so much for this tutorial. I have been trying to replicate this exact workbook for 10 groups, and also use the "CHOOSE" AND "RANDBETWEEN" functions to randomize the values of column A into the array but having a bit of trouble doing so. Would this be possible to set this up? Really appreciate your help!

I am trying to use your formula (downloaded the spreadsheet) to create divide 253 students (value) into 15 groups equally. I tried to edit the code...but i'm getting an error message when trying to adjust the array.

Tamara Smith,

If you are trying to expand the array formula and get an error, try this:

The array formula in column C is entered in cell range C4:C25.

Select cell your new cell range, example C4:C27

Click in formula bar.

Press and hold CTRL + SHIFT. Press Enter to create a new array formula for your new range.

I recommend you use the User Defined Function, it is much easier to work with.
