  2. 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.

  3. 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)”

  4. 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.

  5. 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.

    • 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.

  6. 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
