I am, to be honest a serious noob when it comes to web development but I am looking for help I have a heart.json file that I need transfer to a database and looking for a solution. In the file I have the following data:

      {"activities-heart":[{"dateTime":"2016-04-08","value":{"customHeartRateZones":[],"heartRateZones":[{"caloriesOut":1720.78208,"max":99,"min":30,"minutes":972,"name":"Out of Range"},{"caloriesOut":313.1456,"max":139,"min":99,"minutes":59,"name":"Fat Burn"},{"caloriesOut":0,"max":169,"min":139,"minutes":0,"name":"Cardio"},{"caloriesOut":0,"max":220,"min":169,"minutes":0,"name":"Peak"}],"restingHeartRate":73}}]
    ,"activities-heart-intraday":{"dataset":[
{"time":"00:00:00","value":83},
{"time":"00:01:00","value":80},
{"time":"00:02:00","value":76},
{"time":"00:03:00","value":78},
{"time":"00:04:00","value":78},
{"time":"00:05:00","value":79},
{"time":"00:06:00","value":79},
{"time":"00:07:00","value":78},
{"time":"00:08:00","value":76},

{"time":"00:18:00","value":76},
{"time":"00:19:00","value":76},
{"time":"00:20:00","value":78},
{"time":"00:21:00","value":83},
{"time":"00:22:00","value":76},
{"time":"00:23:00","value":74},
{"time":"00:24:00","value":75},
{"time":"00:25:00","value":74},
{"time":"00:26:00","value":75},
{"time":"00:27:00","value":75},
{"time":"00:28:00","value":75},
{"time":"00:29:00","value":77},
{"time":"00:30:00","value":82},
{"time":"00:31:00","value":82}
