Hi,

[Excel 2007]
I have a huge list of prices and alot are- negative
but are't supposed to be, how can I do it to alot at once?

Apply Filter just to show numbers smaller than 0.
Then copy a "-1" to clipboard. Select the filtered result, and choose "Paste
special | Mulitply".

Alternative:
In an additional column use following formula:
=IF(A2<0;A2*-1;A2)
Then copy this column and paste just values into the other column.
