Excel SEQUENCE function - create a number series automatically

In this tutorial, you will learn how to create a number sequence in Excel with formulas. Additionally, we'll show you how to auto generate a series of Roman numbers and random integers - all by using a new dynamic array SEQUENCE function.

The times when you had to put numbers in sequence in Excel manually are long gone. In modern Excel, you can make a simple number series in a flash with the Auto Fill feature. If you have a more specific task in mind, then use the SEQUENCE function, which is specially designed for this purpose.

Excel SEQUENCE function

The SEQUENCE function in Excel is used to generate an array of sequential numbers such as 1, 2, 3, etc.

It is a new dynamic array function introduced in Microsoft Excel 365. The result is a dynamic array that spills into the specified number of rows and columns automatically.

The function has the following syntax:

SEQUENCE(rows, [columns], [start], [step])

Where:

Rows (optional) - the number of rows to fill.

Columns (optional) - the number of columns to fill. If omitted, defaults to 1 column.

Start (optional) - the starting number in the sequence. If omitted, defaults to 1.

Step (optional) - the increment for each subsequent value in the sequence. It can be positive or negative.

  • If positive, subsequent values increase, creating an ascending sequence.
  • If negative, subsequent values decrease, producing a descending sequence.
  • If omitted, the step defaults to 1.

The SEQUENCE function is only supported in Excel for Microsoft 365, Excel 2021, and Excel for the web.

Basic formula to create a number sequence in Excel

If you are looking to populate a column of rows with sequential numbers starting at 1, you can use the Excel SEQUENCE function in its simplest form:

To put numbers in a column:

SEQUENCE(n)

To place numbers in a row:

SEQUENCE(1, n)

Where n is the number of elements in the sequence.

For example, to populate a column with 10 incremental numbers, type the below formula in the first cell (A2 in our case) and press the Enter key:

=SEQUENCE(10)

The results will spill in the other rows automatically.
Creating a 1 column sequence with a formula

To make a horizontal sequence, set the rows argument to 1 (or omit it) and define the number of columns, 8 in our case:

=SEQUENCE(1,8)
Formula to generate a horizontal sequence

If you'd like to fill a range of cells with sequential numbers, then define both the rows and columns arguments. For instance, to populate 5 rows and 3 columns, you'd use this formula:

=SEQUENCE(5,3)
Using the SEQUENCE function to fill a range of cells

To start with a specific number, say 100, supply that number in the 3rd argument:

=SEQUENCE(5,3,100)
A sequence starting at a specific number

To generate a list of numbers with a specific increment step, define the step in the 4th argument, 10 in our case:

=SEQUENCE(5,3,100,10)
A sequence incrementing by a specific step

Translated into plain English, our complete formula reads as follows:
Excel SEQUENCE formula

SEQUENCE function - things to remember

To efficiently do a sequence of numbers in Excel, please remember these 4 simple facts:

  • The SEQUENCE function is only available with Microsoft 365 subscriptions and Excel 2021. In Excel 2019, Excel 2016 and earlier versions, it does not work since those versions do not support dynamic arrays.
  • If the array of sequential numbers is the final result, Excel outputs all the numbers automatically in a so-called spill range. So, be sure you have enough empty cells down and to the right of the cell where you enter the formula, otherwise a #SPILL error will occur.
  • The resulting array can be one-dimensional or two-dimensional, depending on how you configure the rows and columns arguments.
  • Any optional argument that is not set defaults to 1.

How to create a number sequence in Excel - formula examples

Though the basic SEQUENCE formula does not look very exciting, when combined with other functions, it takes on a whole new level of usefulness.

Make a decreasing (descending) sequence in Excel

To generate a descending sequential series, such that each subsequent value is less than the preceding one, supply a negative number for the step argument.

For example, to create a list of numbers starting at 10 and decreasing by 1, use this formula:

=SEQUENCE(10, 1, 10, -1)
Formula to Make a decreasing sequence in Excel

Force a two-dimensional sequence to move vertically top to bottom

When populating a range of cells with sequential numbers, by default, the series always goes horizontally across the first row and then down to the next row, just like reading a book from left to right. To get it to propagate vertically, i.e. top to bottom across the first column and then right to the next column, nest SEQUENCE in the TRANSPOSE function. Please note that TRANSPOSE swaps rows and columns, so you should specify them in the reverse order:

TRANSPOSE(SEQUENCE(columns, rows, start, step))

For example, to fill 5 rows and 3 columns with sequential numbers starting at 100 and incremented by 10, the formula takes this form:

=TRANSPOSE(SEQUENCE(3, 5, 100, 10))

To better understand the approach, please have a look at the screenshot below. Here, we input all the parameters in separate cells (E1:E4) and create 2 sequences with the below formulas. Please pay attention rows and columns are supplied in different order!

Sequence that moves vertically top to bottom (row-wise):

=TRANSPOSE(SEQUENCE(E2, E1, E3, E4))

Regular sequence that moves horizontally left to right (column-wise):

=SEQUENCE(E1, E2, E3, E4)
A formula to generate a two-dimensional sequence that moves vertically

Create a sequence of Roman numbers

Need a Roman number sequence for some task, or just for fun? That's easy! Build a regular SEQUENCE formula and warp it in the ROMAN function. For example:

=ROMAN(SEQUENCE(B1, B2, B3, B4))

Where B1 is the number of rows, B2 is the number of columns, B3 is the start number and B4 is the step.
Creating a sequence of Roman numbers

Generate an increasing or decreasing sequence of random numbers

As you probably know, in new Excel there is a special function for generating random numbers, RANDARRAY, which we discussed a few articles ago. This function can do a lot of useful things, but in our case it cannot help. To generate either an ascending or descending series of random whole numbers, we'll be needing the good old RANDBETWEEN function for the step argument of SEQUENCE.

For example, to create a series of increasing random numbers that spills in as many rows and columns as specified in B1 and B2, respectively, and start at the integer in B3, the formula goes as follows:

=SEQUENCE(B1, B2, B3, RANDBETWEEN(1, 10))

Depending on whether you want a smaller or bigger step, supply a lower or higher number for the second argument of RANDBETWEEN.
Formula to generate a series of increasing random integers

To make a sequence of decreasing random numbers, the step should be negative, so you put the minus sign before the RANDBETWEEN function:

=SEQUENCE(B1, B2, B3, -RANDBETWEEN(1, 10))
Formula to create a series of decreasing random integers

Note. Because the Excel RANDBETWEEN function is volatile, it will generate new random values with every change in your worksheet. As the result, your sequence of random numbers will be continuously changing. To prevent this from happening, you can use Excel's Paste Special > Values feature to replace formulas with values.

Excel SEQUENCE function missing

Like any other dynamic array function, SEQUENCE is only available in Excel for Microsoft 365 and Excel 2021 that support dynamic arrays. You won't find it in pre-dynamic Excel 2019, Excel 2016, and lower.

That's how to create sequence in Excel with formulas. I hope the examples were both useful and fun. Anyway, thank you for reading and hope to see you on our blog next week!

  2. Hello Sir,

    Thanks for your help in advance. Every time a record is added to excel I have to generate a sequence number automatically. Sequence=Stage.Phase.Next Number - Can you please help how to do this in excel.

    Stage Phase Sequence
    1 1 1.1.1
    1 1 1.1.2
    1 2 1.2.1
    2 2 2.2.1
    2 3 2.3.1
    2 3 2.3.2

      • Pattern is Stage.Phase.Next Incremental number in that Stage.Phase

        Stage.......Phase.......Sequence
        1000...........1..............1000.1.1
        1000...........1..............1000.1.2
        1000...........1..............1000.1.3
        2000...........2..............2000.2.1
        2000...........2..............2000.2.2
        1000...........2..............1000.2.1
        1000...........2..............1000.2.2

        Hope it makes sense...thank you!

        • I did it successfully using COUNTIF. Thank you for your time!

  3. Correction to previous post -

    The format for both methods in my first post got off-alignment when I submitted.
    Here is my attempt to correct the formatting of the 2 methods so that it's readable (I hope it doesn't get messed up again).

    Method 1
    ========

    Tab Cell E1
    ==== ========
    01 01-Jan-2022
    02 =('01'!E1+1)
    03 =('02'!E1+1)
    04 =('03'!E1+1)
    05 =('04'!E1+1)

    Method 2
    ========

    Tab Cell E1
    ==== ========
    01 01-Jan-2022
    02 =('01'!E1+1)
    03 =('01'!E1+2)
    04 =('01'!E1+3)
    05 =('01'!E1+4)

  4. I was searching Google for a better way to do the following and your website popped up. I hope you can help and that it’s not something that can’t be done.
    I have a workbook for each month with either 28,30 or 31 tabs/sheets – one for each day depending on the month.
    I have a date field in the same cell (E1) for each tab - date format is dd-mmm-yyyy.
    I would like the same formula for cell E1 in each tab that increments the date without me having to edit the formula in cell E1 in each tab to change the tab name (Method 1) or increment number (Method 2) to point to the previous tab and add the increment number.
    I have the following 2 formulae that works but I have to change each tab (from tab ‘02’ onwards) to either point to the previous tab name and add 1 or add an increasing increment number to tab name ‘01’. Is there a way to specify the previous tab without having to actually name it – ie. is there a variable name that represents the previous tab ? Here is what currently works, but to me is a bit clumsy.
    Thanks, in advance, for any suggestions.

    Method 1

    Tab Name Cell E1
    ======== ==========
    01 01-Jan-2022
    02 =('01'!E1+1)
    03 =('02'!E1+1)
    04 =('03'!E1+1)
    05 =('04'!E1+1)
    etc etc

    Method 2 - it also works if I do this :

    Tab Name Cell E1
    ======== ===========
    01 01-Jan-2022
    02 =('01'!E1+1)
    03 =('01'!E1+2)
    04 =('01'!E1+3)
    05 =('01'!E1+4)
    etc etc

    • Hello!
      You can only get the name of the previous worksheet using a VBA macro. Regular Excel formulas can only get the name of the sheet where the cell is located:

      =MID(CELL("filename",Sheet1!A2),SEARCH("]",CELL("filename",Sheet1!A2))+1,31)

    • Method 1

      Tab Name . . . . Cell E1
      ======== . . . . ===========
      01 . . . . . . . . 01-Jan-2022
      02 . . . . . . . . =('01'!E1+1)
      03 . . . . . . . . =('02'!E1+1)
      04 . . . . . . . . =('03'!E1+1)
      05 . . . . . . . . =('04'!E1+1)
      etc . . . . . . . . etc

      Method 2 - it also works if I do this :

      Tab Name . . . . Cell E1
      ======== . . . . ===========
      01 . . . . . . . . 01-Jan-2022
      02 . . . . . . . . =('01'!E1+1)
      03 . . . . . . . . =('01'!E1+2)
      04 . . . . . . . . =('01'!E1+3)
      05 . . . . . . . . =('01'!E1+4)
      etc . . . . . . . . etc

  5. Hi, is it possible to arrange the sequence formula to add number until the end of the table and automatically add a number if the table row range is extended?

    • Hello!
      In the first argument of the SEQUENCE function, you can use the COUNTA function, which will count the number of rows with data in the table. When adding. data in column A, the SEQUENCE function will add one more value.

      =SEQUENCE(COUNTA(A:A),1,1,1)

      I hope my advice will help you solve your task.

  6. I am attempting to create a series of mobile numbers. The first four digits and final two digits should not change.
    Example:
    567-000-042
    567-000-142
    567-000-242
    567-000-343

    The series should create a list of all possible combinations from 567-000-042 to 567-999-942 (only the 4th-7th digits will change. The first 3 digits and final two digits should not change.) Thank you.

  12. Hello,

    I have a question regarding the "n" in the SEQUENCE Function.
    Can it be unknown?

    From a table, I would like the formula to list all the data that are above 13%. I can do this using the INDEX, SORT and FILTER functions. But I do not know how many people will be above 13%. Is there a solution to this?

    My formula is as per the below:

    =INDEX(SORT(FILTER(Master!F4:AC248,Master!AC4:AC248>=13%),24,-1),SEQUENCE(20),{1,24})

    Thanks,

    Matt

    • Hello!
      In the SEQUENCE function, specify the maximum number of values (for example, 245). To ignore errors, use the IFERROR function.

      =IFERROR(INDEX(SORT(FILTER(Master!F4:AC248,Master!AC4:AC248>=13%),24,-1),SEQUENCE(245),{1,24}),"")

      Hope this is what you need.

      • Hi Alexander,

        Thank you for taking the time to reply and apologies for the delay of my answer.

        Unfortunately this does not work for me so had to change the formula to the below:

        =INDEX(SORT(FILTER(Master!B4:AC243,(Master!S4:S243="GBP")*(Master!M4:M243=""),"No results"),28,-1),SEQUENCE(20),{5,28})

        So what this does is giving me the 20 top percentages. But only 8 of them are above 13%.
        How can I make sure that with this formula, it removes the percentages that are under 13%?
        (if this is possible).

        Thanks,

        Matt

        • Hi!
          Without seeing your data it is difficult to give you any advice.
          If you are fetching data from column AC, add a filter condition to the formula:

          FILTER(Master!B4:AC243,(Master!S4:S243=”GBP”)*(Master!M4:M243=””)*(Master!AC4:AC243>13%),”No results”)

          I hope I answered your question.

          • Hi Alexander,

            Works a treat! Thank you so much!

    Thanks in advance for the help

  15. Hi Sir,

    I would like to make following sequence, which would be changing based on names in other column. The number of rows with the same name is random - sometimes 5 rows, sometimes 1 row:

    2021-1000 John
    2021-1000 John
    2021-1000 John
    2021-1001 Tim

    2021-1001 Tim
    2021-1002 James
    2021-1002 James
    2021-1003 Michael

    I would appreciate your help.

    • Hi!
      What you want to do is not sequence. This is a random number of duplicates. I'm really sorry, looks like this is not possible with the standard Excel options.

  16. Hello, I am trying to make a SEQUENCE based on the text in the cell next to it.

    Column B can be either IC, IG, IB, or any other 2 letter
    Column C is a number list 21001 21002 21003 and so on.

    However the number can repeat based on the letters in Column B. So I need the sequence to be based on the next available number that relates to the letters in column B.

    I hope that make sense

    • Hello!
      To make a sequence of numbers with a condition, use the formula

      =21000+COUNTIF($B$2:B2,B2)

      Hope I understood the problem correctly.

      • It did work thank you. Now if I can get my co workers to stop skipping number

        • Hello I had a follow up on this. I changed the formula a little to exclude texts from the count so it looks like this now.
          =21000+COUNTIFS('2022'!$D$3:D3,D3,'2022'!$K$3:K3,"CO",'2022'!$K$3:K3,"NCCO")+1
          My problem is when I go to the next cell the is jumps numbers equal to how many cells are used
          EX.
          =21000+COUNTIFS('2022'!$D$3:D5,D4,'2022'!$K$3:K5,"CO",'2022'!$K$3:K5,"NCCO")+1
          =21000+COUNTIFS('2022'!$D$3:D7,D5,'2022'!$K$3:K7,"CO",'2022'!$K$3:K7,"NCCO")+1
          =21000+COUNTIFS('2022'!$D$3:D9,D6,'2022'!$K$3:K9,"CO",'2022'!$K$3:K9,"NCCO")+1
          ^ ^ ^
          I put arrows where the numbers jump. Why would it do that and not follow the order? I can not seem to stop this.

  17. I am constantly having to create numbering sequences that look like this:

    100 000001
    100 000002

    three numbers, space and then 6 numbers with only the last 6 numbers increasing. What would be the formula to achieve that?

    Thanks

  18. I am in need of a way to have a number increase by one each day for a production report. Example

    4 departments in separate columns. Above each heading is the number of days worked. Is there a way increase those days by 1 automatically each day?

    Thanks in advance!

  19. Is there a way to sequence numbers if the numbers look like this------

    PI-2021-07-0480
    PI-2021-07-0481

    Please advise -

  20. Hi,

    what if I have number series like
    [1,2,3,4,5], [11,12,13,14,15], [21,22,23,24,25] and so on in one column until some hundred,
    is there any way to do this?
