QJSonArray to QString conversion

Question

I have this 2 variables, and I want to convert data to dataToString.

QJSonArray data;

Qstring dataToString;

In data there is a huge json like:

{
    "properties": [
        {
            "version":"1",
            "finish":"0",
            "num":3,
            "running":false,
            "time":"00:20:00",
            "player1":"John",
            "player2":"",
            "player3": "Peter",
            "player4":"",
            "team1":"",
            "team2":"",
            "tournament":"",
            "lap":""
        }
    ],
    "game": [
        {
            "serve":true,
            "score":"32",
            "data":"0"
        }
    ]
}

How can I do it ? Thanks.

To quote the documentation :

You can convert the array to and from text based JSON through QJsonDocument.

In other words, all you need to do is this:

QJsonArray data;
QJsonDocument doc;
doc.setArray(data);

QString dataToString(doc.toJson());

That's all there is to it!
