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
