Excel SEQUENCE function

Introduction

One of the most powerful yet underused functions in Excel is the SEQUENCE function. This versatile tool allows you to quickly generate arrays of sequential numbers, either horizontally or vertically, with ease. Whether you’re a financial analyst tracking payments or a project manager organizing tasks, this function can significantly reduce manual work and streamline data entry.

In this blog, we’ll explore everything you need to know about the SEQUENCE function in Excel from its syntax to practical examples and how it can help you work smarter, not harder. Let’s dive into the details!

What is the SEQUENCE Function?

The SEQUENCE function in Excel allows users to generate a list of sequential numbers in an array. It’s especially useful when you need to automatically generate data, such as dates, numbers, or even steps in a process.

Key Features:

  • It can generate one-dimensional or two-dimensional arrays of numbers.
  • You can specify the starting point and increment between each value.
  • It can be used as part of more complex formulas to generate numeric arrays that are then processed or analyzed further.

SEQUENCE Function Syntax

The general syntax of the SEQUENCE function is as follows:

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

  • rows (Required): The number of rows to return in the array.
  • columns (Optional): The number of columns to return in the array.
  • start (Optional): The starting value for the sequence. Defaults to 1 if not provided.
  • step (Optional): The value by which each number increments. Defaults to 1 if not provided.

How to Use the SEQUENCE Function

The SEQUENCE function is incredibly flexible, allowing you to create both vertical and horizontal sequences of numbers. Let’s look at a few examples to understand its potential:

1. Generate a Vertical List of Numbers If you want a vertical list of numbers from 1 to 10, you would use:

=SEQUENCE(10, 1)

This returns:

1
2
3
4
5
6
7
8
9
10

2. Generate a Horizontal List of Numbers If you prefer the numbers horizontally, you can switch the row and column arguments:

=SEQUENCE(1, 10)

This returns:

1 2 3 4 5 6 7 8 9 10

3. Customizing the Start and Step You can customize both the start number and the step between each value. For example, if you want to start at 100 and increment by 10, you would use:

=SEQUENCE(5, 1, 100, 10)

This returns:

100
110
120
130
140

4. Generate a Sequence of Dates Since Excel dates are essentially serial numbers, you can use SEQUENCE to create a list of sequential dates. For example, to generate the next 10 days starting today:

=SEQUENCE(1, 10, TODAY(), 1)

This will return:

January 29, 2025 | January 30, 2025 | January 31, 2025 | February 1, 2025 | February 2, 2025 | February 3, 2025 | February 4, 2025 | February 5, 2025 | February 6, 2025 | February 7, 2025

5. Count Down from a Specific Number The SEQUENCE function can also generate a countdown. For example, to count down from 10 to 0:

=SEQUENCE(11, 1, 10, -1)

This will return:

10
9
8
7
6
5
4
3
2
1
0

Practical Examples of Using SEQUENCE

1. Sequence of Months You can use the SEQUENCE function to generate a list of months for any given year. Let’s say you want the months for the year 2022:

=TEXT(EDATE(DATE(2022,1,1), SEQUENCE(12, 1, 0)), “mmmm”)

This formula will return:

January | February | March | April | May | June | July | August | September | October | November | December

2. Dynamic Calendar Using SEQUENCE, you can easily generate a dynamic calendar that adjusts based on a given start date. For example, to generate the first 7 days of a month, you can use:

=SEQUENCE(7, 1, DATE(2025,1,1), 1)

This would give you:

January 1, 2025 | January 2, 2025 | January 3, 2025 | January 4, 2025 | January 5, 2025 | January 6, 2025 | January 7, 2025

Dataset Example: Monthly Revenue Tracker

Let’s create a simple dataset using the SEQUENCE function to track monthly revenue for the year 2025.

MonthRevenue
January10,000
February12,000
March11,500
April13,000
May14,500
June15,000
July16,000
August17,000
September18,000
October19,000
November20,000
December22,000

To generate a sequence of months in column A, starting from January 2025, use the following formula in A2:

=TEXT(EDATE(DATE(2025,1,1), SEQUENCE(12, 1, 0)), “mmmm”)

For the corresponding Revenue in column B, simply input the revenue data or use another formula, depending on your needs. You can calculate monthly growth or make predictions based on historical data.
