Your question should be clear and without typo

Are you sure you are getting json data in the same format as you typed in your question or it just a typo?

I assume your json data is like { "account_number": "123", "some_stuff": 231, }

then its just a simple dictionary and you can get the value using valueForKey method.

You may want to look into the streaming API to build NSMutableDictionaries from JSON:

NSData *data = [NSData dataWithContentsOfFile:@"example.json"];

 YAJLParser *parser = [[YAJLParser alloc] initWithParserOptions:YAJLParserOptionsAllowComments];
 parser.delegate = self;
 [parser parse:data];
 if (parser.parserError)
   NSLog(@"Error:\n%@", parser.parserError);

 parser.delegate = nil;
 [parser release];

 // Include delegate methods from YAJLParserDelegate 
 - (void)parserDidStartDictionary:(YAJLParser *)parser { }
 - (void)parserDidEndDictionary:(YAJLParser *)parser { }

 - (void)parserDidStartArray:(YAJLParser *)parser { }
 - (void)parserDidEndArray:(YAJLParser *)parser { }

 - (void)parser:(YAJLParser *)parser didMapKey:(NSString *)key { }
 - (void)parser:(YAJLParser *)parser didAdd:(id)value { }
