JSON double quote mystery

Question

Leaning JSON, I'd like to think that followed the syntax tips to the tee. I wanted to start loading datasets into JSON and manipulating them using Python. Writing the dataset I started entering the data but I kept getting this error.

json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 7 column 2 (char 129)

Although I followed multiple tutorials, I can't get to understand where my error is coming from?

        [
            {
                "name": "x",
                "email": "x@x",
                "location": "Yorkville Village",
                "contacted": "Yes",
            },
            {
                "name": "y",
                "email": "y@y",
                "location": "Yorkville Village",
                "contacted": "Yes",
            },
            {
                "name": "z",
                "email": "info@z.com",
                "location": "Yorkville Village",
                "contacted": "Yes",
            },
        ]

Answer 1

It's expecting "property name enclosed in double quotes", as in "expecting [another] property [with a] name [that is] enclosed in double quotes"; it's expecting another property. This is because you have extra commas at the ends of your k:v pairs.

You want:

        [
            {
                "name": "x",
                "email": "x@x",
                "location": "Yorkville Village",
                "contacted": "Yes"
            },
            {
                "name": "y",
                "email": "y@y",
                "location": "Yorkville Village",
                "contacted": "Yes"
            },
            {
                "name": "z",
                "email": "info@z.com",
                "location": "Yorkville Village",
                "contacted": "Yes"
            }
        ]

Answer 2

The Json you show in your question is not valid because of the last comma you have in every object.

Here's a valid version:

[
    {
        "name": "x",
        "email": "x@x",
        "location": "Yorkville Village",
        "contacted": "Yes"
    },
    {
        "name": "y",
        "email": "y@y",
        "location": "Yorkville Village",
        "contacted": "Yes"
    },
    {
        "name": "z",
        "email": "info@z.com",
        "location": "Yorkville Village",
        "contacted": "Yes"
    }
]

Always check if your JSON is valid using a JSON validator
