# Auto numbering

#### k0915

##### New Member
I would like to have auto-numbering after inserting new row, required that the new row has input any text.

here is the example:

Item no. name
1　　　　Mary
2　　　　Tom
3　　　　Jack
4　　　　Peter
5　　　　John

When I insert new row, I would like to have the row no. only when the column "name" has some text inside, otherwise the auto-numbering will skip the blank row.

Item no. name
1　　　　Mary
2　　　　Tom

3　　　　Jack
4　　　　Peter
5　　　　John

Item no. name
1　　　　Mary
2　　　　Tom
3　　　　Susan
4　　　　Jack
5　　　　Peter
6　　　　John

Would there be any code to do this?
Thank you very much!

### Excel Facts

Can a formula spear through sheets?
Use =SUM(January:December!E7) to sum E7 on all of the sheets from January through December
Assumming your numbers are in Column A, starting in Row 1, instead of putting 2 below the 1, put = A1+1.
Then drag that formula down. (or click back on the cell, then double click the bottom right hand corner of the active cell)
When you add a row. Click on the empty spot and press (control + D), and it should repopulate the numbers to the correct order.

However, I would like to have the row number appears automatically only if i put some text in the cell under the column "name" of the row, and if possible, I would like to have it automatically instead of repopulate the numbers by any steps.

Could you please explain more on how to write the marco?

Thanks

If you don't mind doing a bit of work, a formula will suffice for the basic calculation:

=IF(LEN(B2),COUNTA(\$B\$2:B2),"")

...you'll just need to copy it into the new row(s) you insert.

Nice one Paddy. K0915 was wanting it to autopopulate when a row was inserted. While your formula would produce a similar result, it would still require the formula to be copied down after the insert...or have I got it wrong?

K0915, if you go to the links that I provided it should explain how to write the macro. If you're not proficient in writing macros, I highly recommend using either Paddy's or My formula and copying it down when you insert a new row.
