ascending - descending

[Bonnie WLU]

If I typed data in descending, is there a way for me to copy-paste it so that it reads ascending, without having to re-type it all, or copy-pasting individual cells, etc?

Select the data, Data > Sort, ...

Is it just me? Because I can't see this at all.
That's what I had tried originally, thinking it would be obvious, but I can't for the life of me figure out where this function is.
The data is not in numerical order, or else it would be quite easy to figure out.
ex -
I want
Column A
6
8
5
2

To read:
Column A
2
5
8
6

Thanks to anyone who can point me in the right direction! I'm making power consumption data spreadsheets involving thousands upon thousands of entries...

go to data in the formula bar and click on sort - sorting will take care of numeric and alphanumeric category of sorting. please define
