Modify json file without affecting other nodes and values of it

This is content of json file which I want modify.

{

  "node1": {

    "node11": {

      "node121": {

      },

      "node122": {

        "a1": true,

        "a2": {

          "a21": [

            "a211",

            "a212",

            "a213"

          ],

          "a22": [

            "a221",

            "a222"

          ],

          "a23": [],

          "a24": [

            "a241",

            "a242",

            "a243",

            a244"

          ]

        },

        "a3": {},

        "a4": []

      },

      "node23": {

      },

      "node24": {

      },

      "node25": {

      }

    }

  },

  "node2": [],

  "node3": {

    "node31": {

      "node311": {

        "a3111": "xxx"

      },

      "node312": {

        "a3121": "yyy"

      },

      "node313": {

        "node3131": {

          "a31311": "1",

          "a31312": "2",

          "a31313": "zzz",

        }

      }

    },

    "node21": "a211"

  }

}

So, I need change values of node122 to {}, and change value of a31313 to Z1Z1Z1

And I do not understand example of nsJSON plugin.

Would you play with me in this case ?.

What have you tried so far?

nsJSON::set 'node1' 'node122' /value '{}' /file 'D:\Test\Test.json'

nsJSON::set 'node3' 'node313' 'a31313' /value 'Z1Z1Z1' /file 'D:\Test\Test.json'

nsJSON::Serialize /file 'D:\Test\Test.json'

But it is not as I need.

The plug-in does not like empty objects.

nsJSON::Set /file "$%TEMP%\test.txt"
${IfThen} ${Errors} ${|} MessageBox mb_ok Err ${|}
nsJSON:😁elete 'node1' 'node122' /end
nsJSON::Set 'node1' 'node122' /value '{deleteme:0}'
nsJSON:😁elete 'node1' 'node122' 'deleteme' /end
nsJSON::Set node3 node31 node313 node3131 a31313 /value "Z1Z1Z1"
nsJSON::Serialize /format /file "$%TEMP%\test.txt"

You will not be able to read this again into the plug-in.

Thanks Anders.

It is also remove all node existing other.

Content in test.txt:

{
"node1": {
"node122": {

}
},
"node3": {
"node31": {
"node313": {
"node3131": {
"a31313": "Z1Z1Z1"
}
}
}
}
}

How to keep nodes existing ?. (Keeping the content of other nodes, not affecting them, just manipulating the node we need to change.)
