JSON Parse Error: Expecting 'STRING'

Question

I am using JSONLint to parse some JSON and i keep getting the error:

Error: Parse error on line 1: [{“ product”: [{“
---^ Expecting 'STRING', '}', got 'undefined'

This is the code:

[
    {
        “product” :  [ { “code” : “Abc123”, “description” : “Saw blade”, “price” : 34.95 } ],
        “vendor” : [ { “name” : “Acme Hardware”, “state” : “New Jersey” } ]
    },

    {
        “product” :  [ { “code” : “Def456”, “description” : “Hammer”, “price” : 22.51 } ],
    },

    {
        “product” :  [ { “code” : “Ghi789”, “description” : “Wrench”, “price” : 12.15 } ],
        “vendor” : [ { “name” : “Acme Hardware”, “state” : “New Jersey” } ]
    },

    {
        “product” :  [ { “code” : “Jkl012”, “description” : “Pliers”, “price” : 14.54 } ],
        “vendor” : [ { “name” : “Norwegian Tool Suppliers”, “state” : “Kentucky” } ]
    }
]

Oh ok looked it up and replaced all of them and it worked thanks! — yitzih

JSON string literals must use normal quote characters ("), not smart quotes (“”).

It's also worth noting that the JSON is still invalid even after converting to normal quote characters. There is a trailing comma after “price” : 22.51 } ],. There is no item that follows it, so the comma should be removed.

I've just made this mistake using single quotes so don't use those either :)

You're using some unicode double quotes characters. Replace them with the normal " double quotes.

You also had some extra comma at the end in the second element.

Now it's alright

[
    {
        "product" :  [ { "code" : "Abc123", "description" : "Saw blade", "price" : 34.95 } ],
        "vendor" : [ { "name" : "Acme Hardware", "state" : "New Jersey" } ]
    },

    {
        "product" :  [ { "code" : "Def456", "description" : "Hammer", "price" : 22.51 } ]
    },
    {
        "product" :  [ { "code" : "Ghi789", "description" : "Wrench", "price" : 12.15 } ],
        "vendor" : [ { "name" : "Acme Hardware", "state" : "New Jersey" } ]
    },
    {
        "product" : [ { "code" : "Jkl012", "description" : "Pliers", "price" : 14.54 } ],
        "vendor" : [ { "name" : "Norwegian Tool Suppliers", "state" : "Kentucky" } ]
    }
]

JSON must use normal quote characters("), not smart quotes for(“”) for string literals.

To get the normal quote in JSON data format: right-click on browser window and select - view page source.

This is how I save the MySQL text format and get the json_decode data

[{"5":[29,30,5],"6":[1,2,3],"7":[4,5,6]}]

$row_days= $rows['days'];

var_dump(json_decode($row_days, true));

Result array (size=1)

0 => array (size=3) 5 => array (size=3) 0 => int 29 1 => int 30 2 => int 5 6 => array (size=3) 0 => int 1 1 => int 2 2 => int 3 7 => array (size=3) 0 => int 4 1 => int 5 2 => int 6

For me it was because I was doing the following in an older JavaScript framework. But might not be the case with modern JS frameworks.

object.age = 31

instead of the better recognized way:

object["age"] = 31
