The SEQUENCE function is a useful function in Google Sheets. It’s a powerful way to generate numbered lists.

`=SEQUENCE(rows, columns, start, step)`

As arguments for the SEQUENCE function, you specify 1) the number of rows, 2) the number of columns, 3) a start value, and 4) a step size.

Arguments 2, 3, and 4 are optional. However, if you want to set them you need to include the previous ones (e.g. if you want to set a step size in argument 4, then you need to set 1, 2, and 3 as well).

Keep this order in mind as you look through the examples below and you’ll soon understand how the function works.

## 1. Ascending list of numbers

`=SEQUENCE(5)`

## 2. Horizontal list of numbers

Set the row count to 1 and the column count to however many numbers you want e.g. 5:

`=SEQUENCE(1,5)`

## 3. Two-dimensional array of numbers

Set both row and number values:

`=SEQUENCE(10,5)`

## 4. Start from a specific value

Set the third argument to the value you want to start from e.g. 100:

`=SEQUENCE(5,1,100)`

## 5. Use a custom step

Set the fourth argument to the size of the step you want to use, e.g. 10:

`=SEQUENCE(5,1,1,10)`

## 6. Descending numbers

Set the fourth argument to -1 to count down:

`=SEQUENCE(5,1,5,-1)`

## 7. Negative numbers

Set the start value to a negative number and/or count down with negative step:

`=SEQUENCE(5,1,-1,-1)`

## 8. Dates

Dates are stored as numbers in spreadsheets, so you can use them inside the SEQUENCE function. You need to format the column as dates:

`=SEQUENCE(5,1,TODAY(),1)`

## 9. Decimal numbers

Unfortunately you can’t set decimal counts directly inside the SEQUENCE function, so you have to combine with an Array Formula e.g.

`=ArrayFormula( SEQUENCE(5,1,10,1) / 10 )`

## 10. Constant numbers

You’re free to set the step value to 0 if you want an array of constant numbers:

## 11. Monthly sequences

Start with this formula in cell A1, which gives the numbers 1 to 12 in a column:

`=SEQUENCE(12)`

In the adjacent column, use this DATE function to create the first day of each month (formula needs to be copied down all 12 rows):

`=DATE(2021,A1,1)`

This can be turned into an Array Formula in the adjacent column, so that a single formula, in cell C1, outputs all 12 dates:

`=ArrayFormula(DATE(2021,A1:A12,1))`

Finally, the original SEQUENCE formula can be nested in place of the range reference, using this formula in cell D1:

`=ArrayFormula(DATE(2021,SEQUENCE(12),1))`

This single formula gives the output:

1/1/2021

2/1/2021

.

.

.

12/1/2021

It’s an elegant way to create a monthly list. It’s not dependent on any other input cells either (columns A, B, C are working columns in this example).

With this formula, you can easily change all the dates, e.g. to 2022.

Building in steps like this a great example of the Onion Method, which I advocate for complex formulas.

## 12. Text and Emoji sequences

You can use a clever trick to set the SEQUENCE output to a blank string using the TEXT function. Then you can append on a text value or an emoji or whatever string you want to create a text list.

For example, this repeats the name “Ben Collins” one hundred times in a column:

`=ArrayFormula(TEXT(SEQUENCE(100,1,1,1),"")&"Ben Collins")`

And, by using the CHAR function, you can also make emoji lists. For example, here’s a 10 by 10 grid of tacos:

`=ArrayFormula(TEXT(SEQUENCE(10,10,1,1),"")&CHAR(127790))`

Have you got any examples of using the SEQUENCE function?
