Answer

got the solution to this.  
1) inner query to extract data from Jason structure.. specific array  
2) un nesting both the keys and value pair form the structure. check the syntax

SELECT    
DISTINCT m.key AS PROGRAMID,TRIM(UPPER(CAST(m.value AS VARCHAR)))AS PROGRAM    
from  
(SELECT json_extract(programidudf, '$.MAP') as Program_jason   
FROM "tableaureports"."global_udf_parquet" where programidudf is not null)  
CROSS JOIN   
UNNEST   
(  
  (map_keys(CAST(CAST(Program_jason AS JSON) AS map))) ,  
  (map_values(CAST(CAST(Program_jason AS JSON) AS map)))   
)  
AS m(key,value)
