@Werner Stinckens​  If you look at the Schema that was shown above, it has many levels and sub-levels, like: Struct, Array. In this Schema I created is returning only null values, I don't know where I'm going wrong.

schema = StructType([ 
    StructField('fields', StructType([ 
       StructField('comment', StructType([  
        StructField("comments",ArrayType( StructField('body', StringType())),True),
       ])),
    ])),          
    StructField('id', StringType()), 
    StructField('key', StringType()), 
    StructField('self', StringType())
])  
 
 
 
df = spark.createDataFrame([response],schema)
 
 
 
 
 
 
 
df = df.withColumn("fields", explode((("fields"))))\ 
.withColumn("comment", explode((("fields.comment"))))\ 
.withColumn("comments", explode((("comment.comments"))))
