This script exports rows from specified tables to the CSV format in the output window for any tables structure. Hope, the script will be helpful for you -

DECLARE 
      @TableName SYSNAME
    , @ObjectID INT

DECLARE [tables] CURSOR READ_ONLY FAST_FORWARD LOCAL FOR 
    SELECT 
          '[' + s.name + '].[' + t.name + ']'
        , t.[object_id]
    FROM (
        SELECT DISTINCT
              t.[schema_id]
            , t.[object_id]
            , t.name
        FROM sys.objects t WITH (NOWAIT)
        JOIN sys.partitions p WITH (NOWAIT) ON p.[object_id] = t.[object_id]
        WHERE p.[rows] > 0
            AND t.[type] = 'U'
    ) t
    JOIN sys.schemas s WITH (NOWAIT) ON t.[schema_id] = s.[schema_id]
    WHERE t.name IN ('<your table name>')

OPEN [tables]

FETCH NEXT FROM [tables] INTO 
      @TableName
    , @ObjectID

DECLARE 
      @SQLInsert NVARCHAR(MAX)
    , @SQLColumns NVARCHAR(MAX)
    , @SQLTinyColumns NVARCHAR(MAX)

WHILE @@FETCH_STATUS = 0 BEGIN

    SELECT 
          @SQLInsert = ''
        , @SQLColumns = ''
        , @SQLTinyColumns = ''

    ;WITH cols AS 
    (

    SELECT

            FROM cols c
            ORDER BY c.column_id
            FOR XML PATH, TYPE, ROOT).value('.', 'NVARCHAR(MAX)'), 1, 2, '')
        , @SQLColumns = STUFF((SELECT CHAR(13) +
            CASE

                ELSE

            END
            FROM cols c
            ORDER BY c.column_id
            FOR XML PATH, TYPE, ROOT).value('.', 'NVARCHAR(MAX)'), 1, 10, 'CHAR(13) + '''' +')

    DECLARE @SQL NVARCHAR(MAX) = '    
    SET NOCOUNT ON;
    DECLARE 
          @SQL NVARCHAR(MAX) = ''''
        , @x INT = 1
        , @count INT = (SELECT COUNT(1) FROM ' + @TableName + ')

    IF EXISTS(
        SELECT 1
        FROM tempdb.dbo.sysobjects
        WHERE ID = OBJECT_ID(''tempdb..#import'')
    )
        DROP TABLE #import;

    SELECT ' + @SQLTinyColumns + ', ''RowNumber'' = ROW_NUMBER() OVER (ORDER BY ' + @SQLTinyColumns + ')
    INTO #import
    FROM ' + @TableName + ' 

    WHILE @x < @count BEGIN

        SELECT @SQL = STUFF((
        SELECT ' + @SQLColumns + ' + ''''' + '
        FROM #import 
        WHERE RowNumber BETWEEN @x AND @x + 9
        FOR XML PATH, TYPE, ROOT).value(''.'', ''NVARCHAR(MAX)''), 1, 1, '''')

        PRINT(@SQL)

        SELECT @x = @x + 10

    END'

    EXEC sys.sp_executesql @SQL

    FETCH NEXT FROM [tables] INTO 
          @TableName
        , @ObjectID

END

CLOSE [tables]
DEALLOCATE [tables]

In the output window you'll get something like this (AdventureWorks.Person.Person):
