JSON structure to table form in awk, bash
Hello guys,

I want to parse a JSON file in order to get the data in a table form.

My JSON file is like this:
Code:
{
   "document":{
      "page":[
         {
            "@index":"0",
            "image":{
               "@data":"ABC",
               "@format":"png",
               "@height":"620.00",
               "@type":"base64encoded",
               "@width":"450.00",
               "@x":"85.00",
               "@y":"85.00"
            }
         },
         {
            "@index":"1",
            "row":[
               {
                  "column":[
                     {
                        "text":""
                     },
                     {
                        "text":{
                           "#text":"Text1",
                           "@fontName":"Arial",
                           "@fontSize":"12.0",

                     },
                     {

   }
}

I've been trying with awk doing like below, but I get an output far from what I´d like:
Code:
awk -F: '
        /"#text"/      {a01=$2}
        /"@data"/      {a02=$2}
        /"@fontName"/  {a03=$2}
        /"@fontSize"/  {a04=$2}
        /"@fontStyle"/ {a05=$2}
        /"@format"/    {a06=$2}
        /"@height"/    {a07=$2}
        /"@type"/      {a08=$2}
        /"@width"/     {a09=$2}
        /"@x"/         {a10=$2}
        /"@y"/         {z=a01" "a01" "a02" "a03" "a04" "a05" "a06" "a07" "a08" "a09" "a10" "$2; print z}' input.json

|"85.00",,coded",
|"83.42"",coded",
|"124.82",coded",
|"69.62",,coded",
|"83.42",,coded",
|"97.22",,coded",

I'd like to get an output like this(where NaN is to know that for that parameter there is no value):
Code:
   #text @data @fontName @fontSize @format @height          @type  @width      @x      @y
0    NaN   ABC       NaN       NaN     png  620.00  base64encoded  450.00   85.00   85.00
1  Text1   NaN     Arial      12.0     NaN   12.00            NaN   71.04  121.10   83.42
2  Text2   NaN     Arial      12.0     NaN   12.00            NaN  101.07  121.10  124.82
3  Text3   NaN     Arial      12.0     NaN   12.00            NaN  363.44   85.10   69.62
4  Text4   NaN     Arial      12.0     NaN   12.00            NaN  382.36   85.10   83.42
5  Text5   NaN     Arial      12.0     NaN   12.00            NaN  435.05   85.10   97.22

May someone help me out with this problem. Thanks
