Parse json file to HTML table

Hello,
  I json file  with the following data:

"Summary":"A test json file",
  "uniq": {
    "fileA": {
      "Duplicates":"2",
      "DuplicateFiles":[
         {"File":"FileA1"},
         {"File":"FileA2"}
      ]
    },
    "FileB": {
      "Duplicates":"2",
      "DuplicateFiles":[
         {"File":"FileB1
         {"File":"FileB2
      ]
    },
    "FileC": {
      "Duplicates":"0",
      "DuplicateFiles":[
      ]
    },
    "FileD": {
      "Duplicates":"4",
      "DuplicateFiles":[
         {"File":"FileD1"},
         {"File":"FileD2"},
		  {"File":"FileD3},
		   {"File":"FileD4},
      ]
    }
 }
 }

Select allOpen in new window

I would like to parse it and display the content in an HTML table
E.G
Summary:

FILE  CNT   DUP
fileA  2       FileA1
                  FileA2
FileB  2      FileB1
                  FileB2
FileC   0
FileD   4    FileD1
                 FileD2
                 FileD3
                 FileD4


How can I parse the file to get the output. Also, is there better output format for the JSON file that would make creating the table easier.

Thanks for your help
