    type Item struct {
   Price json.Number `json:"price"`
   Id    int64 `json:"id"`
}

func HandleJsonData() {

   jsonData := []byte(`[{"id":"1000,"price":"30"},{"id":"1001,"price":50}]`)

   var item Item
   err = json.Unmarshal(jsonData, &item)
   if err != nil {
      fmt.Println(err)
   }

   price, _ := strconv.ParseInt(string(item.Price), 10, 64)
}

    Working code:

    package main

import (
    "encoding/json"
    "fmt"
)

type Item struct {
    ID    string `json:"id"`
    Price int    `json:"price"`
}

func main() {
    jsonData := []byte(`[{"id":"1000","price":30},{"id":"1001","price":50}]`)

    var items []Item
    err := json.Unmarshal(jsonData, &items)
    if err != nil {
        panic(err)
    }

    fmt.Println(items)
}

    json.Unmarshal function to decode the JSON data into a slice of Item structs. The &items argument to json.Unmarshal is a pointer to the slice variable items, which allows the json package to modify the slice directly.
