**Please Note: **
This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), *this tip may not work for you*. For a version of this tip written specifically for later versions of Excel, click here: Automatically Numbering Rows.

Libby wants to insert a row number into column A of her worksheet. She wants the column to reflect the correct number of the row, even when she adds or deletes rows.

There are any number of formulas you can use in column A that will return a row number. Perhaps the easiest is to use the ROW function, like this:

=ROW()

This formula returns the row number of the cell in which the formula appears. If you want to offset the row number returned (for instance, if you have some headers in rows 1 and 2 and you want cell A3 to return a row value of 1), then you can modify the formula to reflect the desired adjustment:

=ROW()-2

Of course, the ROW function isn't the only candidate for your formulas. You can also use a formula that actually examines the contents of the adjacent column (B) and return a row number only if there is something in that adjacent cell.

=IF(TRIM(B1)<>"",COUNTA($B$1:B1)&".","")

This formula, placed in cell A1, examines the contents of cell B1. If there is something there, then the COUNTA function is used to count the number of occupied cells between cell B1 and whatever cell is to the right of where this formula is placed. The formula also places a period after the row number that is returned. Make sure the dollar signs are included, as shown, and then copy the formula down as many cells as necessary to create your row numbers.

The advantage to a formula such as this one is that it checks to see if something is in column B before it returns a row number. This means that you can copy the formula down beyond the actual end of your data rows, and only those rows that have data (triggered by something in column B) will have a row number. The same sort of technique could be used with the ROW function instead of the COUNTA function:

=IF(TRIM(B1)<>"",ROW()&".","")

10 digit mobile number in A1 so how to convert those in b1 to L1

2016-12-02 10:52:25

Gregg Alley

The above formula works well, but if an existing row is deleted, or a new row is inserted, the numbers could change.

That could be prevented however, by creating a data entry form and using VBA to paste the new data into the first empty row of a protected worksheet.

I think the answer to my question may be in this tip... If in A1 I type the any number, but for this exmaple I will use the number "17". I want to see the numbers 1 thru 17 displayed starting in A2-A19. If the number on A1 is updated to "33", then display 1 thru 33 from A2-A34.

I was able to understand only the first part of your request.

In cell A1 type: =(ROW()+4)*10 and copy down as far as needed.

I'm trying to use a formula to number rows throughout my excel worksheet. I have a general ledger in excel and only want to assign numbering to debits or credits. For example: my first row may contain an account number or there maybe no date in the row at all. I want to be able to number every row in the worksheet and then go through and manually delete the numbers for data in rows I do not want to include. Once I delete the number, I want all the sequential numbering to update itself.

I'm not sure I fully understood your request but in the mean while try this - in cell C1 type the hereunder suggested formula and copy along row 1 up to cell A50.

=IF(COLUMN()-3+$A1>$B1,"", COLUMN()-3+$A1)

In cell A1 type a "legal" date.

In cell A2 type: =EDATE(A1,1)

Now, copy cell A2 down up to A24.

"Be careful".

What will happen when she will run the Find & Replace over a column which has:

614614 and 615614 ?

Another way is to use Find and Replace.

- Select the cells you want to change

- Press Ctrl+H

- enter 614 in de 'Find What:'

- enter 615 in 'Replace with:'

- click Replace All

2015-01-08 06:08:37

Michael (Micky) Avidan

The fastest way - without any helper column and/or VBA Programming will be:

* in cell A3 change (type) the new number: 615000

* In A4 type: 615001

* Select both(!) cells > click & hold(!) the lower right corner of cell A4 (the fill handle) and drag down until the last cell you want to fill the sequential numbers and release the mouse.

gerald diamond

=IF(TRIM(B1)<>"",COUNTA($B$1:B1)&".","")

is that, while it will not number rows that have only a space in the b cell, it will count them.

Thus your numbering may not be consecutive.
