@JsonSet(jsonObject, "price", 99000, "int");
@JsonSet(jsonObject, "weight", 2.5, "double");
@JsonSet(jsonObject, "available", true, "bool");
@JsonSet(jsonObject, "manufactureDate", "2025-01-15", "datetime:yyyy-MM-dd");

// Result : {"name":"Product Name","price":99000,"weight":2.5,"available":true,"manufactureDate":"2025-01-15"}
string result = @JsonToString(jsonObject);

Example 2)

// 1. JSON Object Creation
string jsonObj = @JsonStructNew("{}");

// 2. Set properties
@JsonSet(jsonObj, "name", "John", "string");
@JsonSet(jsonObj, "age", 30, "int");
@JsonSet(jsonObj, "isActive", true, "bool");

// 3. Create nested objects
string addressObj = @JsonStructNew("{}");
@JsonSet(addressObj, "city", "Seoul", "string");
@JsonSet(addressObj, "zipcode", "12345", "string");

// 4. Add nested objects
@JsonSet(jsonObj, "address", addressObj);

// 5. Create an array
string phoneArray = @JsonStructNew("[]");
@JsonAppend(phoneArray, "010-1234-5678", "string");
@JsonAppend(phoneArray, "02-123-4567", "string");

// 6. Add an array
@JsonSet(jsonObj, "phoneNumbers", phoneArray);

// 7. Convert to JSON String
string jsonString = @JsonToString(jsonObj);
@MessageBox(jsonString, "jsonString", MB_OK);

// 8. Memory Cleanup
@JsonClear(jsonObj);
@JsonClear(addressObj);
@JsonClear(phoneArray);
