Often, serializing a lot of elements manually in Excel is boring. Fortunately, it is pretty easy to auto-generate number sequences in Excel. To get rid of this monotonous issue, I will show you some easy and handy ways to auto-generate a number sequence in Excel. For the purpose of demonstration, I’m using Microsoft Office 365. No worries if you have another version.

First things first, let’s get to know about the worksheet, which is the basis of our examples today. In this sheet, we have a table of 5 people with their ages. Using this, you will see how to auto generate numbers for each of them. Generally, you see the serial number that belongs to the left of any particular element. But as we intend to look at different ways of generating numbers, we are keeping the methods on the right side. For the purpose of demonstration, I have used the following sample dataset.
1. Applying Basic Addition Method for Excel Auto Generate Number Sequence
In this serialization method, we will increment the previous row number by 1. So, we will add 1 to the previous row number to our current cell.
Steps:
- Firstly, select the cell D5 and put the value as 1.
- Secondly, write the following formula on cell D6.
=D5+1
- Thirdly, press the Enter button and use the AutoFill tool to apply the formula to the rest of the column.
- Finally, you will get your desired sequence.
2. Using Excel AutoFill Method to Auto Generate Number Sequence
If you want to use the AutoFill method, you have two options. However, it includes the Fill Handle and Fill Series. Hence, go through the below parts in order to apply them to our data.
2.1 Applying Excel Fill Handle Tool to Generate Number Sequence Automatically
In general, you have to insert a value into a row and select it as an active cell. Then you will see a small circular box at the bottom right to complete the operation.
Steps:
- Initially, select the active cell D5 and put 1.
- Similarly, select cell D6 and put 2.
- After that, select the cells, and you will see that Filler icon at the bottom right.
- Lastly, drag it down in order to complete the operation.
2.2 Using Fill Series to Auto Generate Number Sequence in Excel
For the Fill Series method, you don’t need to insert two values as previously. Simply Insert the value into one row, and the rest of the part will be completed automatically. In this way, you can create a number sequence in Excel without dragging.
Steps:
- At first, select cell D5 and input 1 as the value.
- Then, go to the Editing command from the Home tab and select Series from the Fill option.
- Here, set Columns under Series and Step value: 1 and Stop value: 5 from the Series dialog box.
- Next, press ok.
- Finally, you will find the sequence.
3. Inserting Excel ROW Function to Auto Generate Number Sequence
Usually, The ROW function returns the row number of the cell you are presently in (active cell). So, select an empty row from the first in order to get 1 anywhere in the dataset. Let’s follow the instructions below to generate the number rows automatically in Excel.
Steps:
- Firstly, write the following formula in cell D5.
=ROW(A1)
- Finally, use the AutoFill tool to the entire column to get the final result.
4. Applying Excel COUNTA Function for Auto Generate Number Sequence
Furthermore, another method worth mentioning here is the COUNTA function. However, the COUNTA function counts the number of cells that are not empty within a range. Moreover, this method will help you serialize the rows that are not empty. Go through the process below to generate an automatic numbering sequence in Excel.
Steps:
- Initially, write the following formula in cell D5.
=COUNTA($B$5:B5)
- Lastly, hit the Enter key and utilize the AutoFill tool to get the result.
5. Using OFFSET Function in Excel for Getting Number Sequence Automatically
Generally, the OFFSET function returns the reference of a cell or a range of cells. Here, you have to insert three parameters within an OFFSET function. However, go through the steps below to add an automatic serial number with formula in Excel.
Steps:
- At first, insert the following formula in cell D5.
=OFFSET(E5,-1,0)+1
Here, you have to select an empty cell for the first value. Otherwise, it will show errors.
- Again, select cell D6 and insert the formula below.
=OFFSET(D6,-1,0)+1
- At the end, apply the AutoFill tool, and the output will be as below.
6. Inserting Excel SEQUENCE Function to Auto Generate Number
Furthermore, you can generate a number sequence using a function called SEQUENCE. Using the SEQUENCE function, you have to provide only one parameter, rows.
Steps:
- At first, write down the following formula in cell D5.
=SEQUENCE(5)
- Lastly, it will provide the final result.
7. Creating Repeated Number Sequence Automatically in Excel
In this part, I will show you how to automatically create a repeating number sequence. Usually, it will repeat the number after a particular value. Here, I have used the IF function. However, you can follow the steps below to AutoFill the repeated sequential numbers in Excel.
Steps:
- At first, click on cell D5 and put the value as 1.
- After that, enter the following formula on cell D6 and press Enter.
=IF(D5=3,1,D5+1)
- Finally, apply the AutoFill tool to get the final sequence.
8. Generating Auto Number Sequence in Excel Ignoring Blank Cells
Often, you may have to work with a number of sequences with blank cells, and you don’t want to provide a number sequence into the blank cells. Here, I have combined the IF function and the COUNTA function. However, follow the steps below to create a number sequence ignoring blank cells. For the purpose of demonstration, I have slightly changed the dataset.
Steps:
- Initially, write down the following formula in cell D5.
=IF(C5<>"",COUNTA($C$5:C5),"")
Formula Breakdown
The formula uses the IF and COUNTA functions and returns the serial number. Here’s how this formula works:
- COUNTA($C$5:C5)—-> counts the cell C5.
- Output:1
- =IF(C5<>””,COUNTA($C$5:C5),””)—-> checks the empty cell and returns the serial number as 1 for non-empty cell and noting for empty cell.
- Output:1
- After that, hit the Enter key and utilize the AutoFill tool to the whole column.
- Finally, the output will appear in the following image.
9. Using Excel Named Range Tool to Auto Generate Number Sequence
Last but not least, you can use a relative reference named range in order to auto-generate number sequences. For this reason, you have to define a particular name as the function. However, go through the following steps.
Steps:
- At first, go to the Formulas tab and select the command Define Name.
- Secondly, write UP as the Name and insert the following formula into Refers to.
=INDIRECT("R[-1]C",FALSE )
- Thirdly, press OK.
- Again, select cell D5 and enter the formula below.
=SUM(UP,1 )
- Finally, you will receive the desired output.
How to Auto Generate Number Sequence with Text in Excel
Moreover, you can use Excel’s TEXT and ROW functions to create a number sequence with text. Let’s go through the description below to create a number sequence with text in Excel.
Steps:
- First, type the following formula in cell D5.
=B5&TEXT(ROW(A1)-1,"-00-")&C5
Formula Breakdown
The formula uses the TEXT and ROW functions and returns the username. Here’s how this formula works:
- ROW(A1)—-> returns the row number of cell A1, which is 1.
- ROW(A1)-1—-> becomes
- Output:0
- TEXT(0,”-00-“)—-> turns into the text format of 0.
- TEXT(ROW(A1)-1,”-00-“)—-> simplifies to
- Output: ‘-00-’
- B5&TEXT(ROW(A1)-1,”-00-“)&C5—-> results into
- “Lynn” & “-00-” & “25 Years”—-> returns the serial with texts.
- Output: Lynn-00-25 Years
- Lastly, use the AutoFill tool in order to apply the same formula to the entire column.
