how to remove element from JSON array in golang?

I have a array of JSON string

ex:

[
 {
  "name":"abc"
  "age":25
 }
 {
  "name":"xyz"
  "age":"26"
 }
]

In run time I want to remove "name" from array . How can we do it . I don't want to unmarshal it .

[
     {
      "age":25
     }
     {
      "age":"26"
     }
  ]
