I'm trying to retrieve what initially looked like a normal JSON from a website. But it is a JavaScript object which is not a valid JSON. Is there a way to convert this string to JSON using python?
Example would be:
{
firstName:"John",
lastName:"Doe",
age:50,
eyeColor:"blue",
dimensions:[
{
height: "2",
width: "1"
}
]
}
Use a parser with a non-strict mode that can handle such input. I've been recommending demjson for stuff like this, since it's the first viable candidate that came up when I searched for python non-strict json parser.
>>> demjson.decode("""{
... firstName:"John",
... lastName:"Doe",
... age:50,
... eyeColor:"blue",
... dimensions:[
... {
... height: "2",
... width: "1"
... }
... ]
... }""")
{u'eyeColor': u'blue', u'lastName': u'Doe', u'age': 50, u'dimensions': [{u'width
': u'1', u'height': u'2'}], u'firstName': u'John'}
Until 2018, demjson was also hosted at http://deron.meranda.us/python/demjson/, now archived.
I am afraid that Python does not understand JavaScript. If you can use Node.js, it is easy to convert the input to JSON.
Edit: Of course you can also use the JavaScript console of every browser to do this.
> d = {
... firstName:"John",
... lastName:"Doe",
... age:50,
... eyeColor:"blue",
... dimensions:[
... {
..... height: "2",
..... width: "1"
..... }
... ]
... };
{ firstName: 'John',
lastName: 'Doe',
age: 50,
eyeColor: 'blue',
dimensions: [ { height: '2', width: '1' } ] }
> JSON.stringify(d)
'{"firstName":"John","lastName":"Doe","age":50,"eyeColor":"blue","dimensions":[{"height":"2","width":"1"}]}'
