I think you need to copy the code given at the bottom under resources, and execute it from your SSMS.
Then run
EXECUTE [dbo].[WriteResultsToCsvFile]
@sqlcmd = 'select * from sys.objects'
,@filename = 'c:\object_export.txt'
You might get error that 'clr enabled' is disable and enable it. If you get that error then run these commands
EXEC sp_configure 'show advanced options', 1
GO
RECONFIGURE
GO
EXEC sp_configure 'clr enabled', 1
GO
RECONFIGURE
GO
Then run the above execute command to export the data into a file or you can change that select statement to what ever you want to export into a file.
I am not sure what this is doing in his script
"EXEC sys.sp_addextendedproperty" with his(Jonathan) user name but it is working for me.
GREAT WORK.
