You can simply do by this using the map method and the spread operator.
const users = [
  {roleName: "Admin", roleId: 14, configuration: "false", projects: "false", fTs: "false"},
  {roleName: "PM", roleId: 15, configuration: "false", projects: "false", fTs: "false"}
];

const usersFormatted = users.map(user => {
    return {
        ...user,
        configuration: user.configuration === 'true'
    }
});
console.log(usersFormatted);

/* Output
[
   {roleName: "Admin", roleId: 14, configuration: false, projects: "false", fTs: "false"},
   {roleName: "PM", roleId: 15, configuration: false, projects: "false", fTs: "false"}
]

to convert a string into bool we use below code in typecript
var stringValue = "true";
var boolValue = (stringValue =="true");   //returns true

//OR

var stringValue = "true";
var boolValue = JSON.parse(stringValue);   //returns true
