Attribute name change in array with mapper

Hi,

Could you please help me to change attribute names from input json?

Input

{
“title”: “students”,
“items”:
[
{
“name”: “Tom Cruise”,
“course”: “EEE”
},
{
“name”: “Robert Downey Jr.”,
“course”: “CSC”
}
]
}

I need to change output as

{
“title”: “students”,
“items”:
[
{
“Name”: “Tom Cruise”,
“Course”: “EEE”
},
{
“Name”: “Robert Downey Jr.”,
“Course”: “CSC”
}
]
}
