Excel auto fill column by X+++..Y++..Z+

Question

How do I autofill the values in between?

Answer 1

Select Column A, CTRL+G -> Blanks -> OK Type = press UpArrow , then press CTRL+ENTER

See this link for explanation. It is basically find all blanks and enter a formula to all of them.

EDIT: as @kurast pointed out for safety/sanity reasons select all and Copy and Paste Special as Values.

Answer 2

I've not found a great way to do this, ever. There's a not-great workaround I use from time to time:

1. Insert a column after A
2. Copy the first value over - so B1: =A1
3. Starting at B2, drag the formula of B2: =IF(A2 = "", B1, A2)
4. Copy B:B
5. Paste values into A:A
6. Delete column B

Answer 3

Make another column to generate them for you. Insert a new column B, make B1 = A1 , then use this formula in B2 :

=IF(A2="",B1+1,A2)

And drag it down; it will perform the logic you want.

Then you can copy column B, and paste special values -> values to "hard-code" the results.

Edit: I am not sure exactly what you mean by "auto-fill"; @corsiKa's formula will result in

Mine will result in:
