Hello I want to read json file as follow;

{

  "M": {

  "row": [

  {

  "col1": "c00"

  },

  {

  "col1": "c10",

  "col2": "c11"

  },

  {

  "col1": "c20",

  "col2": "c21",

  "col3": "c22"

  }

  ]

  }

}

Next to reading I need to assign to two dimentional array, but without giving "col1","col2","col3" a lot.  The array is for example, Array[3][] = {{"c00"},{"c10","c11"},{"c20","c21","c22"}};

Thanks for helping.
