Question

In a Google Docs Spreadsheet, I would expect this formula:

=ARRAYFORMULA(ROW())

to fill the column like:

[   1]
[   2]
[   3]
[   4]
  ...

but instead it stops at 1. What is happening here? Is there another way to get the current row number in an arrayformula?

Answer 1

You need to specify a cell-range argument for ROW() in order to have more than one value.

Try it this way:

=ARRAYFORMULA(ROW(A1:A10))

This will fill a column with row numbers from 1 to 10.
