Reading JSON file using Import Mapping Method

Hi All, 

I am uploading the JSON file and expecteing it to store in the Mendix database using Import Mapping. 

The data is not imprted for attached JSON snippet. The entity structure is starting from mnemonic i didn't include data in the JSON structure.

So i want to exclude the metadata also as shown below.

 { "data": {"mnemonic": [
      {"code": "VOF","name": "V.O.F.","type": "CLIENT","client": [
          {"entity": "NV","code": "TEST1"
          }
        ],"outright-client": [
          {"account-number": 2132
          }
        ]
      },"meta-data": {"count": 1234,"as-of": "20170215132000GMT","date-time": "20170215132000GMT"
  }
}
