Short description and why it's useful

• Correction of identation:

// wrong format
{
    "array":
    [
        "any value"
    ],
    "object": { "key": "value"}
}

// corrected format
{
    "array": [
        "any value"
    ],
    "object": {
        "key": "value"
    }
}

• Adding separation space after the colon in the object's key:

// wrong format
{
    "key":"value"
}

// corrected format
{
 "key":  "value"
}
