To use in SMSS, switch your output from "grids" to "text" (ctrl+t) in the SQL editor then execute in the following manner

EXEC @return_value = [utils].[SqlTableToCSharp]
@tableName = N''
GO

NOTE: You may also have to go into
TOOLS->OPTIONS->QUERY RESULTS->SQL SERVER->RESULTS TO TEXT

and change the maximum number of chars displayed in a column to a higher value, as SMSS will truncate a text output at 256 chars by default (Thanks MS!!)
