in c++ how would you read from a txt file using stringstream

the txt file is as followed:

{name: joseph, age: 19, gpa: 4.0}

{name: maria, age: 23, gpa: 3.4}

{name: kevin, age: 21, gpa: 3.8}

but is there a way to dissect the data name, age, gpa

into something like

{

stringstream ss(data);

ss >> arrayData[i].name;

ss >> arrayData[i].age;

ss >> arrayData[i].gpa;

}
