Change value from zero to NULL

Hello,

When I import data from a .csv-file, MS SQL Server 2008 gives the value "0" if there is no value at all for a particular date. I want to have NULL as a value instead in these cases.

How would I go about if I wanted to change the value "0" to "NULL" in a column in one of my tables?
