        I know how to parse json.
        But if I try:
        QJsonDocument::fromJson
        then object()
        I only get the first json element.

          [/quote]Sorry, I didn't read your original question and title properly.

          Since you have multiple JSON documents in your string, I guess you'll have to split them into multiple strings and feed them into multiple QJsonDocuments.

          You can detect the start and end of the documents by counting the number of '{' and '}' characters as you iterate through your original string.
