json validtor code example

Example 1: how to verify json format is valid

I use Gson class in order to convert a
Json object into a java object.
If it works without any error, it means that it is a valid json format...

import com.google.gson.Gson;

public class JSONUtils {

  Gson gson = new Gson();

  public boolean isJSONValid(String jsonInString) {
      try {
          gson.fromJson(jsonInString, Object.class);   
          return true;
      } catch(com.google.gson.JsonSyntaxException e) { 
          return false;
      }
  }
}

Example 2: JSON validate

# Get countries starting with letter P
S=pd.Series(['Finland','Colombia','Florida','Japan','Puerto Rico','Russia','france'])
S[S.str.match(r'(^P.*)')==True]

Example 3: json beautify

fetch('https://fakestoreapi.com/products')
            .then(res=>res.json())
            .then(json=>console.log(json))
