​

Example: Convert an Object to JSON

1. Create an Object Block with values:

   {
     "name": "John Smith",
     "age": 30,
     "hobbies": ["reading", "hiking"]
   }
   

2. Add a To JSON Block and connect the Object Block to its input.
3. Run the flow. The output will be the stringified JSON:

   {"name":"John Smith","age":30,"hobbies":["reading","hiking"]}

Error Handling

• Handles circular references by throwing an error
• Non-JSON-serializable values (like functions) will be omitted
