Experts know the importance of serial numbers. Serial numbers are like salt. You never feel their presence but their absence makes your data tasteless.

Yes, they are important.

Because with a serial number you can have a unique identity to each entry of your data.

But the sad news is, adding them manually is a pain. It’s really hard to add a number in every row one after another.

Hi Puneet,

I find the links to your 14 methods to be inactive..?

However, I hope you can help me;

I am looking for a way to auto add serial numbers in a column when a new row is inserted at the bottom of a table, but the serial numbers should filter with the records if I run a sort on another column..?

Thus, the serial number “marries” the record and move along with it when I run a sort.

So, when I run a sort on the serial number column afterwards, the table restores to its original form.

It works if the serial numbers are entered manually, thus fixed (not determined by formulas in the cells), but I need it to autofill when a new row is inserted at the bottom of the table..?

Thank you!

Will appreciate so much!!

this can be done with VBA and Excel Table

Dear Puneet,

I just came accross your site, Indeed its informative, however I am looking for one of the solution/ the way to insert serial no at column based to Random input on multiple criteria at row/column cells

Exampls, I am trying to maintain a Voucher Series with Alpha numeric as Sr.No. based on the date sequence, my row “Date” input for particular transaction might change any any given point, suppose row2,3,4/Catagory X has Date as 1-Jan-2020, than my sequence for voucher Sr will be 1,2,3, but if I change row4 Date input to 1-Dec-2020 by keeping the same catagory as X than my Voucher should have Sr. as 1 as my date is older then row 2,3 based to catagory. if catagory input criteria changed Z then it will be 1 only, same way if I change row 3 catagory as Z than keeping same date (1-Jan-20),than Voucher no should be 2

Hopefully you understand on what is desired.

Please to know me on my email

Voucher Sr, Catagory, Date,

1 X 1-Jan-2020

2 X 1-Jan-2020

3 (2) X (Z) 1-Jan-2020

4 (1) Z 1-Dec-2020

Thank you in advance

I want to create serial number automatically, but they should then remain as absolute values and should not change, if i add or sort data in table. How to do that

I’m using spreadsheet to work on students results and their age simultaneously with my phone, coz I don’t have desktop computer. But the problem I’m encountering right now is the arrangement of serial numbers and date of birth. Like for instance, from numbers 1 to 73 is not in the same line with numbers 74 to 112. Numbers 1 to 73 is at the normal column, while numbers 74 to 112 is at the side of the column. Lastly, students which their date of birth is from 10 – 31. Like for example; 10 – 02 – 2007 will be at the normal column. But students which their date of birth are below 10 will be at the side of the column. For example; 09 – 02 – 2007. Please how can I arrange it in line properly. Thanks in anticipation.

It would be great if you share a snapshot with me -> puneet(at)excelchamps(dot)com

I am not clear with your Method #10. can you explain clearly?

I have a serial numbers as A,B,C,D,…Z. If I delete one of the row, the series of A,B,C,D,E…Z should not be changed. it should again shows A,B,C,D,E,…..Z. please help…its urgent.

I WANT TO ADD SR NUMBERS AS 1(18-19) AND THAN 2(18-19) IN A COLUMN BUT BECAUSE OF () I AM NOT ABLE TO ADD SERIAL NUMBERS PLS HELP

You need to use ROW function and then add (18-19) as a test so if I have to insert serial number in cell A1 then the formula would be =ROW()&”(18-19)”

How to add Serial no. having figure more than 15 digits, like 89080068770002819

Give me a better example. what do you mean by 15 digits? 🙂

what the formula for method 10

awesome work !

excel

I often use MAX to achieve automated numbering, with cell formatted as a number ending in decimal point (“#,##0.”), with a dependency on the cell to the right having a value in it.

For example

With Row 1 having column headings, I would have the following formula in call A2 –

=if( $B2 = “” , “” , max( $A$1:$A1) + 1

which can then be dragged / copied down to the bottom of the sheet or area you need it to apply to. Useful to apply step by step documentation of steps in a process, where blank lines between any steps do not get numbered.

I need to insert automatic serial no.s like :

TK001

TK002

TK003 ….and so on.

with condition that when there is some entry in the next coloum even then this serial no. has auto entered.

DID YOU GOT IT ? I AM SEARCHING FOR THE SAME

i want to get a series like 1,1,2,2,3,3,4,4,5,5,.. and so on. How to do that?

Sub AddSerialNumbers()

Dim i As Integer

On Error GoTo Last

i = InputBox(“Enter Value”, “Enter Serial Numbers”)

For i = 1 To i

ActiveCell.Value = i

ActiveCell.Offset(1, 0).Activate

ActiveCell.Value = i

ActiveCell.Offset(1, 0).Activate

Next i

Last:

Exit Sub

End Sub

Let’s say your sequence begins in cell A2.

In cell A2, enter a 1

In cell A3, enter this formula:

=IF(COUNTIF($A$2:A2,A2)=1,A2,A2+1)

Use the fill handle to drag that down as far as needed.

hii

i want to make auto fill column like 3 9 27 81

Multiply with three and drag down.

Its owesome Yaar

Thanks for your words. 🙂

I often use COUNTA(A$1:A1) to add serial number.for filering i’d love SUBTOTAL(3,B$1:B1)

Thanks for sharing.

The other day I learned the following:

– in Cell A1 type the number 1

– while holding down CTRL button, use Fill Handle on bottom right hand corner of cell A1 and drag down

– you will see the numbers filled in sequential order as you drag down

Thanks Derek

Well,

this is my favorite as it works with filtering:

=subtotal(3,a$1:a1)

Wow, MMA,

Thanks for sharing.

Do I miss something here? I have put the subtotal function in A1 and copied it down. What I get is 0 (zero) in all my cells. I use the norwegian version and the 3 points to COUNTA, is that correct?

formula should be =SUBTOTAL(3,B$1:B1)
