How to parse JSON data, using javascript

Question

Can someone please show me how I can get my JSON data and use it in javascript?

My data looks like this...

[{
    "id": "1",
    "0": "1",
    "filename": "CONFIG 1",
    "1": "CONFIG 1",
    "setting_name": "Parameter 501",
    "2": "Parameter 501",
    "setting_value": "true",
    "3": "true"
}, {
    "id": "1",
    "0": "1",
    "filename": "CONFIG 1",
    "1": "CONFIG 1",
    "setting_name": "Parameter 502",
    "2": "Parameter 502",
    "setting_value": "true",
    "3": "true"
}, {
    "id": "1",
    "0": "1",
    "filename": "CONFIG 1",
    "1": "CONFIG 1",
    "setting_name": "Parameter 503",
    "2": "Parameter 503",
    "setting_value": "false",
    "3": "false"

    "id": "1",
    "0": "1",
    "filename": "CONFIG 1",
    "1": "CONFIG 1",
    "setting_name": "Parameter 505",

    "0": "1",
    "filename": "CONFIG 1",
    "1": "CONFIG 1",
    "setting_name": "Parameter 506",
    "2": "Parameter 506",

    "setting_name": "Parameter 508",
    "2": "Parameter 508",
    "setting_value": "19",

    "id": "1",
    "0": "1",
    "filename": "CONFIG 1",
    "1": "CONFIG 1",
    "setting_name": "Parameter 509",
    "2": "Parameter 509",
    "setting_value": "19",
    "3": "19"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 502",
    "2": "Parameter 502",
    "setting_value": "false",
    "3": "false"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 503",
    "2": "Parameter 503",
    "setting_value": "true",
    "3": "true"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 504",
    "2": "Parameter 504",
    "setting_value": "6",
    "3": "6"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 505",
    "2": "Parameter 505",
    "setting_value": "16",
    "3": "16"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 506",
    "2": "Parameter 506",
    "setting_value": "17",
    "3": "17"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 507",
    "2": "Parameter 507",
    "setting_value": "3",
    "3": "3"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 508",
    "2": "Parameter 508",
    "setting_value": "18",
    "3": "18"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 509",
    "2": "Parameter 509",
    "setting_value": "19",
    "3": "19"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 501",
    "2": "Parameter 501",
    "setting_value": "false",
    "3": "false"
}, false]

Basically I have four fields... id, filename, setting_name and setting_value.

I need to know how I can get this and convert it into a javascript array, so that I may use it withing my logic. N
