Add Column to CSV Windows PowerShell

Question

I have a fairly standard csv file with headers I want to add a new column & set all the rows to the same data.

Original:

column1, column2
1,b
2         


        

Answer 1

The ShayLevy's answer also works for me!

If you don't want to provide a value for each object yet the code is even easier...

Import-Csv file.csv | 
Select-Object *,"column3" | 
Export-Csv file.csv -NoTypeInformation
