your json invalid - correct format:
{ "nederlands" : [ { "length7" : [ { "word" : "android" }, { "word" : "camping" }, { "word" : "koekjes" } ] }, { "length8" : [ { "word" : "androids" }, { "word" : "campings" }, { "word" : "campings" }, { "word" : "campings" }, { "word" : "campings" }, { "word" : "campings" }, { "word" : "scheppen" } ] }] } at moment, "nederlands" in format of jsonarray (it's holding multiple jsonobjects) response missing square brackets. if parse "nederlands" jsonarray , remove "length" jsonobjects 1 one should able make work
