How to validate JSON string in Golang 1.20
0In this video we are going to generate source code for the GoLang Program, How to validate JSON string using chatGPT.
After generating we will verify and run the generated code.
IMPORTANT NOTE on SOURCE CODE: only source code that are acceptable by the youtube description box will be displayed.
##############SOURCE CODE#########################
package main
import (
"encoding/json"
"fmt"
)
func main() {
jsonString := `{"name": "John Doe", "age": 30, "email": "johndoe@example.com"}`
// Parse the JSON string
var jsonData interface{}
err := json.Unmarshal([]byte(jsonString), &jsonData)
if err != nil {
fmt.Println("Invalid JSON string:", err)
return
}
// Check if the parsed data is a map[string]interface{}
dataMap, ok := jsonData.(map[string]interface{})
if !ok {
fmt.Println("Invalid JSON string: not a key-value pair")
return
}
// Print the parsed data
fmt.Println("Parsed data:")
for key, value := range dataMap {
fmt.Printf("%s: %v\n", key, value)
}
}

Below is the explanation for the program:
The program first defines a JSON string and assigns it to the jsonString variable. It then uses the json.Unmarshal() function to parse the JSON string into a generic interface{} type. If there is an error while parsing the JSON string, the program will print an error message and exit.
Next, the program checks if the parsed data is a map with string keys and interface{} values. This is the most common format for JSON objects. If the parsed data is not in this format, the program will print an error message and exit.
Finally, the program prints the parsed data using a for loop and fmt.Printf(). This is just an example of what you could do with the parsed data. You could modify this program to do whatever you need with the parsed JSON data.
