JSON Schema for validation JSON object with an array of items of the same type

Question

Can i create json schema for validitaion this object without redesigning json in other form?

{      
        "itemColors": {
          "40": "#12ffd6",
          "69": "#f90861",
          "185": "#063ac3"
        },
        "itemVisible": {
          "32": true,
          "33": true,
          "34": true,
          "36": true,
          "37": true,
          "38": true,
          "39": true,
          "40": true,
          "41": true,
          "55": true,
          "56": true,
          "69": true,
          "185": true,
          "187": true,
          "196": true,
          "197": true,
          "198": true
        } 

}

Objects can have different numbers of properties.

Values for ItemColors:

must be of type string
do not have to be unique
can be any number of them

Same thing for itemVisible but values must be of type boolean

You need to provide more detail. Yes, you can create a schema for this specific JSON document; however, I suspect you don't want that. What is it that you actually want to validate? Is it enough to validate that the values for itemColors should be of type string? That they should be unique? That there should be a maximum of 3 of them? Without this information we cannot help you and your post will probably be closed. — tom redfern

You can specify the schema of unspecified properties using "additionalProperties" :

{
   "properties" : {
       "itemColors" : {
            "type" : "object",
            "additionalProperties" : {
                "type" : "string"
            }
       },
       "itemsVisible" : {
            "type" : "object",
            "additionalProperties" : {
                "type" : "boolean"
            }
       }
   }
}
