Question

I have a JSON file that I would like to create an multi-dimensional array from. This information is stored in a JSON file.

Here is the JSON data.

{
  "table": {
    "columnNames": ["column1", "column2", "column3", "column4"],
    "columnTypes": ["String", "String", "String", "String"],
    "rows": [
      ["data00", "data01", "data02", "data03"],
      ["data10", "data11", "data12", "data13"],
      ["data20", "data21", "data22", "data23"],
      ["data30", "data31", "data32", "data33"]
     ]
   }
}

I need to create an array of arrays from the objects in the “rows” section.

Any help would be appreciated!

Thanks!!!

Answer 1

Once you parse the JSON, the “table.rows” property will already be a multi-dimensional array (2 dimensions, to be specific). All you have to do is access it:

var array2D = parsed.table.rows;

As to parsing, you should probably use something like Crockford’s parser:

var parsed = JSON.parse(rawStringOfJSON);
