This looks like JSON so use appropriate API.

yes it is json response

Hi, you can use QString::split to split the string at the comma, the iterate over the resulting QStringList and check for the key you are looking for, e.g. “noiseRatio”.
Although a real JSON API would probably be easier to use and more versatile.
