Efficient Techniques for Numbering Rows in Excel
The most optimal way to number rows in Excel depends on the type of data you are working with, such as: - Continuous data starting from the first row of the worksheet or from a different row. - Data lists with some empty rows and you only want to number the rows with data.
So, depending on the type of data you have, you choose the most suitable method among those presented by Mytour below:
1. Numbering Rows in Excel Using Fill Handle (Drag and Drop)
The Fill Handle feature in Excel is like a magic wand, effortlessly copying data, formulas, and automatically filling in sequences of numbers. Using Fill Handle to number rows in Excel is the easiest and most popular method. Here's how you do it:
Step 1: In your Excel spreadsheet, input the sequence numbers for the first two cells in the Sequence column.
In this example, Mytour enters 1 into cell A2 and 2 into cell A3 in the STT column.
Step 2: Select the two cells you just filled with numbers, and you'll see a small square icon appear at the bottom right corner of the selection.
Step 3: Hover your mouse cursor over that square icon, and it will transform into a plus sign icon (+). Now, click and hold the left mouse button and drag down to the row where you want.
2. Numbering Rows in Excel using Fill Series
Another method for numbering rows in Excel is by using the Fill Series tool, with the following steps:
Step 1: Enter the number 1 into the first cell of the sequence column. In this example, Mytour enters 1 into cell A2.
Step 2: Click on the Home tab and select Fill > Series under the Editing section located at the top right corner of the screen.
Step 3: In the Series dialog box, choose Columns under Series in and specify the Stop Value as the last sequence number. For example, if there are 10 stores in the article, Mytour will input the Stop Value as 10. Note: If you don't specify a stop position for numbering, Fill Series won't work.
Step 4: Click OK, and the Sequence column in the spreadsheet will be numbered from 1 to 10.
3. Numbering Rows in Excel using the ROW Function
You can also use Excel functions to number rows. With the Fill Handle and Fill Series methods above, the sequence numbers are static values. This means if you add or delete rows in your worksheet, the assigned numbers won't change. Therefore, you'll need to manually update the row numbers to maintain the correct order.
To tackle this issue, you can utilize the ROW function instead of the first two methods. Here's how:
Input the formula '= ROW() - 1' into the first cell of the sequence column (in this example, cell A2), then copy and paste this formula into all remaining cells of the sequence column (you can use the Fill Handle drag-and-drop operation to expedite the process).
Note: The ROW() function displays the current row number. That's why in this example, Mytour subtracts 1 in the formula because the sequence starts from the second row onwards. If your data starts from row number 6, you need to input the formula as '=ROW() - 5'.
The beauty of using the ROW function to number rows in Excel is that when you add or delete rows, the sequence numbers will automatically adjust.
4. Numbering Rows in Excel using the COUNTA Function
The COUNTA function is used to number rows only for rows with data. Input the following formula into the first cell of the sequence column (in this example, cell A2).
A2 = IF(ISBLANK(B2),'',COUNTA($B$2:B2))
For the formula IF(ISBLANK(B2),'',COUNTA($B$2:B2)), we have:
- IF(ISBLANK(B2),'': Check if the adjacent cell in column B is empty. If it is, it will return a blank result.
- COUNTA($B$2:B2): Count the cells containing data, where $B$2:B2 is the range that the COUNTA function is applied to (the first value must always be locked, here it's B2, otherwise the function will error for cells below).
Then, copy and paste the formula into all remaining cells in the sequence column (you can use the Fill Handle drag-and-drop feature).

5. Numbering Rows when Filtering Data in Excel using the SUBTOTAL Function
If you have a large dataset and want to filter it, then copy and paste the filtered data into another worksheet, using the SUBTOTAL function will automatically update the row count, even when you filter the dataset, the row numbers will still be correctly numbered. If you use any of the methods described above, you will notice that the original sequence numbers remain intact. This means that when you copy filtered data, you will have to update the sequence numbers.
For example, consider the following spreadsheet:
After filtering data using the Filter function, some rows have disappeared and the sequence numbers have changed as shown below:
The SUBTOTAL function ensures that even when data is filtered, the sequence column automatically updates and is numbered correctly. Input the following formula into the first cell of the sequence column (in this example, cell A2).
A2 = SUBTOTAL(3,$B$2: B2)
Where,
- Number 3 is interpreted as the COUNTA function in the SUBTOTAL function.
- $B$2: B2 is the range that the COUNTA function is applied to (the first value must always be locked, here it's B2, otherwise the function will error for cells below).
Additionally, you can further combine the method to number rows while skipping cells without data by inputting the following formula into the first cell of the sequence column (in this example, cell A2):
A2 = IF(ISBLANK(B2),'',SUBTOTAL(3,$B$2: B2))
Where:
- IF(ISBLANK(B2),'': Checks if the adjacent cell in column B is empty. If it is, it will return a blank result.
- SUBTOTAL(3,$B$2: B2): Similar to the annotation above.

6. Numbering Rows in Excel using Table Creation
Excel table is an excellent tool you must utilize when working with tabular data. It makes managing and using data much easier. Here's how you can apply it to number rows using Excel tables:
Step 1: Select the entire data range.
Step 2: Click on the Insert > Table tab and choose Table.
Step 3: In the Create Table dialog box, ensure the table range/selection is correct. Then, click OK to create the table.
Step 4: In cell A2 (the first row of the Sequence column), input the following formula:
A2 =ROW(A1)
The ROW function returns the number of the row you reference. For example: =ROW(A1) returns 1.
Step 5: Then, the Sequence column in the spreadsheet will be automatically numbered.
7. Numbering Rows in Excel by Adding 1 to the Previous Row Number
Another quick, concise, and lightweight way to number rows in Excel is by adding 1 to the previous row number. This ensures that the subsequent rows have incremented sequence numbers by 1 unit. Note that this method only applies to continuous data lists starting from the first row of the worksheet. If you delete or insert rows, the sequence numbers won't update. Here's how to do it:
Step 1: Enter the number 1 into the first cell of the Sequence column (here it's cell A2).
Step 2: In cell A3 (the cell directly below the first cell with 1 entered), type the formula:
A3 = A2+1
Step 3: Copy and paste the formula into the remaining cells of the Sequence column. You can use the Fill Handle drag-and-drop operation to expedite the process.
Thus, Mytour has introduced you to some quick ways to number rows in Excel. These methods are applicable to different scenarios. Therefore, depending on your dataset, you choose the method that suits you best.
