title: Adding a Column to Import in Flat File Source Editor
body: <p>I have a CSV file that I use a SSIS package to import into SQL Server.  I am looking at the 'Flat File Source Editor' under 'Data Flow' and I see a list of 'External Column' with the matching 'Output Column'.  If I have a new column in my CSV file, how would I add that to be included in the import?  I don't see an option to add a new column in the Flat File Source Editor.</p>
