Sequence Function in ExcelSequencing your data in an Excel worksheet is a tedious task. But fortunately, those days are long gone! Though many users may think of using the AutoFill feature to list down the numbers series in a sequence. But this modern autofill feature doesn't work if you have a more specified sequential task to perform. Therefore, in such cases, you can use the inbuilt SEQUENCE function, which is specially created for this pursuit. In this tutorial, you will learn what is Sequence function, its syntax, parameter, points to remember, how this formula works and various examples by using the Sequence function to return a new dynamic array by autogenerating a series of Roman numbers and random integers What is Sequence Function?"The SEQUENCE function is an inbuilt Excel function that generates an array of sequential numbers whether number, roman number, alphabets. For example: 1, 2, 3, etc." The SEQUENCE function is a new dynamic array function that generates a list of sequential numbers in an array. Though the resultant array can be onedimensional or twodimensional, determined by the specified parameters i.e., rows and columns. This function always returns a dynamic array that arranging the rows and columns in the specified sequence. The SEQUENCE function is introduced in the new Microsoft Excel 365. Therefore, if you are using the previous Excel versions, this function won't be available. To use this function, make sure to update your Excel version to Excel 365 or above. NOTE: If you are trying to access the Sequence function in previous Excel versions, unlike Excel 2019, Excel 2016, and lower, you won't find it.SyntaxParametersRows (required)  This parameter represents the number of rows to sequence your data. Columns (optional)  This parameter represents the number of columns to fill. If the user doesn't provide this argument, by default it takes 1. Start (optional)  This parameter represents the starting number in the sequence. If the user doesn't provide this argument, by default it takes 1. Step (optional)  This parameter represents the increment or decrement for each subsequent value in the sequence. It can take the following values:
Return TypeThe Excel Sequence Function returns a dynamic array by automatically arranging the rows and columns in the specified sequence. Formula to create a number sequence in Excel If you want to create a column of rows with sequential numbers starting at 1, you can use the Excel SEQUENCE function in its simplest form: To place values in the first row: =SEQUENCE(1) To put value in a column: SEQUENCE(1, n) Where n represents the number of values available in the sequence. For instance, to create a column with 100 numbers, enter the following formula in the first cell (we have takes B2 in our case) and press the Enter button: =SEQUENCE(100) The output will be automatically be spilled in the rows starting from the selected row. Things to Remember about Sequence FunctionBefore working on Microsoft Excel Sequence Function, make sure to go through with the below facts:
Examples:#SEQUENCE Example1: How to create a number sequence in descending order in ExcelIn the below sheet, as you see we have a list of values organised in a random order. As asked in the question, to arrange the values in their descending order using the Sequence function, we just need to do a little trick, i.e., we will supply negative one (1) in the step parameter. Follow the belowgiven steps to fetch the descending sequential series of the abovegiven numbers using the Excel Sequence() function: Step 1: Select a cell to position your Sequenced data Place your mouse cursor to a cell from where you want to start the sequencing of your data. In our case, we have selected cell C2 of our Excel worksheet. Refer to the given below image: STEP 2: Type the SEQUENCE function In the selected cell, we will start your function with the equal to (=) sign followed by the Sequence function. The formula will be as follows: = SEQUENCE( STEP 3: Insert all the parameters
Step 4: The Sequence function will return the output As a result, the SEQUENCE function will return the 10 numbers in descending sequential order. Explanation This function will select 10 values and start the counting from 10. It will subtract 1 from 10, and return 9. Again, it will subtract 1 and return 8, and in the pattern, it will return 10 values in the descending sequential order. #SEQUENCE Example2: How to create a 2D array where sequential order moves vertically top to bottom.When working with an array of cells, the standard sequencing rule goes horizontally across the first row till its last element, and next, it moves down to the next row, in a similar method to reading text from left to right. But in various scenarios, the range of cells is not listed in sequential order as per the given Excel data. To propagate the above data in the top to bottom order across the first column and then right to the next column, we will use the combination of the SEQUENCE function and the TRANSPOSE function. Follow the belowgiven steps to fetch the results using Excel SEQUENCE() function: Step 1: Select a cell to position your Sequenced data Place your mouse cursor to a cell from where you want to start the sequencing of your data. In our case, we have selected cell F2 of our Excel worksheet. Refer to the given below image: STEP 2: Type the SEQUENCE function In the selected cell, we will start your function with the equal to (=) sign followed by the Sequence function. The formula will be as follows: = SEQUENCE( STEP 3: Insert all the parameters
Step 4: The Sequence function will return the output As a result, the regular SEQUENCE function will moves horizontally left to right (columnwise) and return the following maintaining a gap of 10 between the values. Step 5: Nest Sequence function inside the Transpose Function Though the above output is also correct, that's not what we were looking for. In the question, we are asked to create a sequence that moves vertically from top to bottom (rowwise), maintaining order of 10. Therefore, we will use the Transpose function and nest the above Sequence function inside it. The formula will be as follows: =TRANSPOSE(SEQUENCE(3, 3, 10, 10)) Step 6: Excel will fetch you the result Once done, press the enter button and Excel will arrange all the data in the specified sequence where the is arranged in the array sequencing vertically from top to bottom (rowwise). Refer to the below image for your reference. #SEQUENCE Example3: How to create a sequence of Roman numbers in Excel worksheet?Roman numbers are an interesting method to list down your data in Excel. But have you ever tried to create a SEQUENCE formula for Roman numbers? If the answer is no! what are you waiting for? Using the inbuilt Sequence function, try to list down the roman numbers in a specified order. Give it a try; else you can take the hint from the given below steps to wrap the roman numerals in sequential order: Step 1: Select a cell to position your Sequenced data Place your mouse cursor to a cell from where you want to start the sequencing of your data. In our case, we have selected cell F3 of our Excel worksheet. Refer to the given below image: STEP 2: Type the SEQUENCE function In the selected cell, we will start your function with the equal to (=) sign followed by the Sequence function. The formula will be as follows: = SEQUENCE( STEP 3: Insert all the parameters
Step 4: The Sequence function will return the output As a result, the SEQUENCE function will return the numbers arrange in ascending sequential order. STEP 5: Nest Sequence function inside the inbuilt Excel Roman Function In the above output, the sequence is correct, but the values are in numbers, whereas we want them to be sequenced in Roman numbers. Therefore, we will convert the sequenced numbers to roman numbers using Excel's inbuilt Roman function. The formula will be as follows: =ROMAN(SEQUENCE(6, 3, 1, 1)) Step 6: Roman numbers will be sequenced Roman numbers will be sequenced horizontally (left to right) as an output.
